Focused ion beam sputtering yield measurements for cobalt ions on silicon and related materials
Schneider, P.; Bischoff, L.; Teichert, J.; Hesse, E.
The sputtering yield of crystalline, amorphous, and poly-silicon, as well as SiO2 and SiC, was investigated for 35 keV Co+ focused ion beam irradiation using the volume loss method. The sputtered holes were analysed by SEM and surface profiling. For crystalline silicon targets, the sputtering yield was determined as a function of the incident angle of the ions and substrate temperature.

Two-phase flow behaviour during a medium size cold leg LOCA test on PMK-2 (IAEA - SPE-4)
Szabados, L.; Ézsöl, G.; Perneczky, L.; Krepper, E.; Prasser, H.-M.; Schäfer, F.
The experiment to the IAEA standard problem exercise No. 4 was carried out in April 1993 on the integral test facility PMK-2 in Budapest. It was a 3.2 mm break on the downcomer head. The high pressure injection cooling was assumed to be not available. As an accident management measure bleed and feed on the secondary side of the steam generator was applied. Research Center Rossendorf contributed to the experiment of SPE-4 by supplying needle shaped conductivity probes for the measurement of local void fractions in the primary circuit of the PMK-II test facility. In the course of the standard problem exercise No. 4 RCR contributed with posttest calculations using the thermalhydraulic code ATHLET.
The report comprises a description of the initial and boundary conditions of the test and a phenomenological description of the thermalhydraulic events during the transient. The void fraction probe signals yields valuable information for deeper understanding of the thermalhydraulic occurrences and for code validation. This was the case particularly for correction of the level measurement.
A description of the thermalhydraulic occurrences from the viewpoint of code verification is given and the results of RELAP5 (KFKI-AEKI) and of ATHLET-calculations (RCR) are compared. Referring to this description, the sensitivity of the result to main influences is investigated using the ATHLET-code.

In situ observation of the tip shape of Co-Ge liquid alloy ion sources in a high-voltage transmission electron microscope
Driesel, W.; Dietzsch, C.; Hesse, E.; Bischoff, L.; Teichert, J.
For in situ observation in a 1 MeV TEM Co-Ge liquid alloy ion soures (LAISs) were mountet to a special specimen holder revealing the formation of the field-stabilizes Co-Ge liquid alloy cone, the change in the tip shape as a function of the ion emission current, spatial shifts of the liquid alloy cone, and microdroplet emission from Co-Ge LAISs. This has facilitated the better understanding of the ion and microdroplet emission process from Co-Ge LAISs in a large range of ion current. Below the onset voltage the shape of the tip covered with the liquid Co-Ge alloy is spherical. At the onset voltage the Tayler cone is formed. A jetlike protrusion at the cone vertex. The cone half-angle a decreases and the jet length l increases with increasing emission current le. Linear dependences of a and l on Ie are found. Emission of microdroplets is observed at the shanks behind the Tayler cone. The radius of microdroplets varied between 0.035 and 10 µm. These microdroplets are emitted in time intervals of about 0.1 s and more.

Cobalt disilicide interconnects for micromechanical devices
Teichert, J.; Bischoff, L.; Hesse, E.; Schneider, P.; Panknin, D.; Geßner, T.; Löbner, B.; Zichner, N.
A focused ion beam system working with 35 keV Co+ ions has been used to produce CoSi2 interconnects by means of ion beam synthesis. The capability of maskness patterning of the focused ion beam, ist large depth of focus and the possibility of a dynamic focus control allow the fabrication of interconnects in three-dimensional devices with this method. Investigations have been performed using polycrystalline, amorphous and single crystalline silicon substrates. The influence of implantation does has been studied, the electrical resistance and thermal stability of the interconnects has been measured. For room temperature implantation and annealing at 600°C for 1h resistivities between 34 and 60 µ( cm have been obtained for the various substrate materials. CoSi2 interconnects have been found to be thermally stable up to 700°C. In order to demonstrate this method interconnection lines have been fabricated on the sloped walls of deep anisotropically etched grooves 280 µm.

The investigation of different cameras for in-beam PET imaging.
Pawelke, J.; Byars, L.; Enghardt, W.; Fromm, W.-D.; Geissel, H.; Hasch, B.-G.; Lauckner, K.; Manfraß, P.; Schardt, D.; Sobiella, M.
In situ and in vivo treatment plan verification and beam monitoring as well as dose control during heavy-ion tumour therapy can be performed in principle by measurements of range distributions of positron-emitting nuclei by means of PET techniques. For this purpose the performance of different types of positron camera as well as the results of in-beam PET experiments using beams of positron-active ions (15O, 17F and 19Ne with energies of 300-500 AMeV) are presented. Following the deduced performance requirements a PET scanner that is designed for clinical use in experimental heavy-ion therapy at GSI Darmstadt has been built. This limited angle tomograph consists of two large-area detector heads based on position sensitive BGO detectors and is predicted to perform the measurement of the end point of a positron-emitting ion beam for the verification of a treatment plan with a precision better than 1 mm. The maximum dose applied in the patient thereby is of the magnitude of 10 mGy.

Effects of nuclear Coulomb field on two-meson correlations
Barz, H.-W.
Abstract:
The infiuence of the nuclear Coulombfield on two-pion and two-kaon correlations is investigated for sources with charge number of Z = 160. The source radii
extracted from the correlation function determined in sidewards and outwards direction are remarkably affected for meson pairs with average momenta, below 200 MeV/c.

Influence of the first-order polarization on the stopping power for bare charges in the jellium model
Mathar, R. J.
Adding the contribution of the next higher order of the density parameter to the random-phase approximation (the zeroth-order, noninteracting approximation to the subceptibility) improves the calculation of the linear dielectric function of the jellium model. In this paper, the corresponding results by Holas, Aravind, and Singwi (Phys. Rev. B20 (1979) 4912) are picked up to extend the Lindhard-Winter theory of the electronic energy loss in a straightforward manner. As known from static approximations to the local-field correction, the electronic stopping at low ion velocities is enhanced. Above the stopping-power maximum, the first-order dynamic dielectric function delivers a correction of the opposite sign.

Submicron CoSi2-structures fabricated by focused ion beam implantation and local flash lamp melting
Bischoff, L.; Heinig, K.-H.; Teichert, J.; Skorupa, W.
A new way to fabricate submicron CoSi2 structures on Si wafers is presented. The method consists of a combination of focused ion beam (FIB) implantation of Co+ ions and subsequent flash lamp irradiation. With our FIB equipment IMSA-100 one- and two dimensional structures were implanted by writing with a 35 keV Co+ beam which was focused to a spot diameter of 200nm. However, for the porposed method the spot size is not the crucial dimension because the final structure size is controlled by a local melting and recrystallization process in the implanted regions. Here the structure size is determined by the amount of implanted atoms which can be concentrated by the local melting process into the submicron CoSi2 structures. The local melting is caused by heteronucleation at the Si wafer surface during the short period of superheating, which is obtained by intense flash lamp irradiation of 3 or 20 ms duration. Disintegration of implanted CoSi2 wires by precipitate formation during thermal annealing, which was reported by Liddle et al. (Mater. Res. Soc. Symp. Proc. 279 (1993) 881), can be avoided by this method. The CoSi2 structures were analysed by scanning electron microscopy (SEM) and energy dispersiv X-ray analysis (EDX). Dots and wires of about 200 nm diameter and width, respectively, have been fabricated during these first experiments, whilst smaller dimensions seem to be possible in future.

Ermittlung der Neutronendosis von bestrahlten WWER-Reaktordruckbehältermaterialien
Barz, H.-U.; Böhmer, B.; Konheiser, J.; Stephan, I.
In this report is described the theoretical and experimental determination of all needed parameters for the neutron exposure of the different specimens that were irradiated in the Rheinsberg reactor within the period from 1984 until 1988 to obtain data for neutron embrittlement studies.
The methodical approach is represented, possible sources of errors are discussed and all the needed results are collected. The work can be divided into a pure calculation part, into the description of the extraction of the monitors and their gamma spectrometric analysis and into the discussion of the spectrum adjustment procedure which combines experimental and theoretical results. Therefore, this representation deals not only with this special task but gives also a survey about the methodical approach and the state of art in Rossendorf for the general problem of determination of neutron fluences, because the developed methods are generally applicable and not limited to the special problem of neutron embrittlement. Different problems with respect of neutron fluences exist also in Germany.
The calculation of fluences is based on an accurate description of the history of the reactor for all irradiation periods, i.e. the time and space dependence of burnup, power and fisson sources. This information was given for a time and space grid of all fuel elements.
For the calculation of the fluences were not used time dependent fluxes, but at first integral sources of fission neutrons are calculated for different fissionable isotopes. Using these given integral source distributions the fluences were calculated and the results from the different fissionable source were composed. For the improvement of the comparison between experimental and theoretical results a special method was used calculating special integral sources for the given detector, because each detector according to its decay notes another integral source resp. flux distribution, which has to be theoretically corrected.
The basis of all transport calculations was the Monte Carlo method in a special problem adjusted kind. Special procedures were developed and successfully applicated for the reduction of statistical errors. Therefore, also for single specimens results with small statistical errors were obtained. It is remarkable that this accurate method which allows a realistic 3-dimensional description of the system reactor-surroundings could be applied with reasonable calculation times for the great number of needed calculations.

Theoretical Vibration Model of VVER Reactors Considering Fluid-Structure-Interaction
Altstadt, E.; Grunwald, G.; Scheffler, M.; Weiß, F.-P.
A finite-element-model describing the mechanical vibrations of the whole VVER-440 primary circuit is being developed to support the early detection of mechanical component faults. A special fluid-structure-element was developed to consider the reaction forces of the fluid in the downcomer upon the moving core barrel and the rector pressure vessel. It was derived from an approximated analytical 2D-solution of the coupled system of 3D fluid equations and the structural equations of motions. By means of the vibration model all eigenfrequencies up to 30 Hz and the corresponding mode shapes were calculated. It is shown that the fluid-structure-interaction strongly influences those modes exhibiting a relative displacement between reactor pressure vessel and core barrel. Moreover, by means of the model the shift of eigenfrequencies due to the degradation or to the failure of internal clamping and spring elements was investigated. By comparing the frequency spectra of the normal and of the faulty structure, it could be shown that a recognition of such degradations and failures even inside the reactor pressure vessel is possible by pure excore vibration measurements.

Specification of a Technical System to improve the Operational Monitoring of the Zaporosh'ye NPP by the State Supervisory Authority of the Ukraine
Beyer, M.; Carl, H.; Langer, L.; Schumann, P.; Seidel, A.; Zschau, J.; Nowak, K.; Tolksdorf, P.
In order to improve the operational surveillance of a VVER-1000 unit of the Ukrainian nuclear power plant Zaporosh'ye a technical monitoring system has been specified. The system will enable the state regulatory and supervisory bodies to survey the unit operation independently of operators to assess its safety status, and to impose appropriate conditions. Due to its up-to-date configuration the system provides early indication of any operational incident and emission of radioactive materials connected. Based on the system an immediate warning in emergency situations is possible as well as an effective emergency management. For this purpose 49 different operational parameters of the unit, 18 radiological parameters of the unit and the plant site and 6 meteorological parameters are monitored.

First observation of inelastic X-ray scattering from condensed 4He using high energy resolution
Schell, N.; Simmons, R. O.; Burkel, E.
Recently, the suitability of inelastic X-ray scattering for the investigation of solid and fluid 4HE has been demonstraded. For the text experiments an energy resolution of the order of 10-15 meV was used at the backscattering spectrometer INELAX at the storage ring DORIS of DESY, Hamburg. Lattice excitations were observed for momentum transfers along the c axis of h.c.p. helium crystals which were grown in situ at pressures of 54-63 Mpa and at temperatures of 4.2-6.4 K. At 10 k abowve the melting point, engery-loss signals could also be detected from the liquid helium at equivalent momentum transfers.

Comparision of CoSi2 Interconnection Lines on Crystalline and Noncrystalline Silicon Fabricated by Writing Focused Ion Beam Implantation
Teichert, J.; Bischoff, L.; Hesse, E.; Schneider, P.; Panknin, D.; Geßner, T.; Löbner, B.; Zichner, N.
A focused beam of Co+ ions has been used to produce CoSi2 interconnects by means of ion beam synthesis. Investigations have been performed using polysilicon, amorphous and crystalline silicon substrates. The influence of implantation dose and annealing temperature on the resistivity has been studied. For room temperature implantation and annealing 600°C for 1h, a resistivity of about 60µ(*cm has been obtained independent of the subtrate type. The CoSi2 layers have been found to be stable up to 700°C. CoSi2 interconnects have been fabricated on the slope walls of 200µm deep anisotropically etched grooves using a dynamic focus control of the focused ion beam.

1% Cold leg break experiment on PMK-2 Test results and computer code analysis
Ézsöl, G.; Guba, A.; Perneczky, L.; Prasser, H.-M.; Schäfer, F.; Krepper, E.
In the framework of the computer code assessment programme for the VVER-440 type Paks Nuclear Power Plant a 1% cold leg break experiment has been conducted on the PMK-2 integral type test facility. It was followed by calculations using RELAP 5Mod3.1 and ATHLET in order to assess code capabilities. This experiment was started from the nominal operational parameters and it was considered that only the high pressure injection system (HPIS) is available and there is no injection from the safety injection tanks (SIT). This experiment was the repetition of the test measured in 1990 with improved data aquisition system. The first part of this report includes a short description of the facility, the measurement description, the test results including the local void measurement and a short interpretation of the main phenomena. In the second part of the report the analysis performed by the RELAP 5Mod3.1 and ATHLET Mod1.1 Cycle A codes are given.

Ag+ sensitive membran in sub-µm thickness prepared by ion implantation
Möller, D.; Pham, T.; Hüller, J.; Albrecht, J.
AG2S embedded into a 100 nm thin film of SiO2 was fabricated synthetically from ist constituents by ion implantation. The ion sensing characteristics of such film material for Ag+ were shown to be analogous to conventional bulk materials, giving sensitivities <=59 mV per concentration decade.

Leckdetektion an komplizierten dreidimensionalen Topologien
Hessel, G.; Schmitt, W.; Weiß, F.-P.
The well-known methods of the acoustic leak localization using the attenuation differences or propagation time differences (e.g. cross correlation analysis) are restricted to the linear geometry of pipe lines. At complicated three-dimensional topologies they fail because there are several modes of the structure-borne sound that have different propagation velocities and because numerous connecting branches generate multiple sound reflexion. Therefore, a new method for detecting and localizing the leaks at complicated geometrical structures was developed and experimentally proved at an original facility. This approach is based on the detection of the leak induced airborne sound or structure-borne sound as well as on the application of pattern recognition procedures. The efficiency both of Fuzzy Logic and neural networks for the acoustic leak localization could be experimentally proved. Though the method has been prototypically developed for Russian pressurized water reactors of VVER-440 type, it can also be used by the self-learning capability of the classifiers at other pressurized facilities.
