Higher fields and novel designs
Besides conducting its user program, the HLD is engaged in the development of advanced pulsed-magnet technology. Thus, the HLD occupies an exposed position on the international scale by carrying on its 100 T program, a challenging goal which is pursued worldwide only at one other laboratory (Los Alamos (100 T in March 2012)). In addition to the ambitious 100 T project, magnet designs which aim at longer pulse times, lower energy consumption, as well as more homogeneous field profiles are also under development at the HLD.
All coils, including the one which generated the European record, are wound and manufactured in our own workshop.
Fighting against cancer
A related design program of the HLD aims at the development of compact and economic pulsed magnets which will be used for the guidance and energy selection of proton beams. These proton beams will be used for medical therapies, in particular for the controlled treatment of tumors. For this technique which is under development at the HZDR protons are generated by means of pulsed high-intensity laser-light exposure and consequently guided by means of compact pulsed magnets to the patient. In order to bend a proton beam on a small length scale, compact and exact proton-radiation guidance can be realized only through the application of magnet pulses with field amplitudes of several 10 T. The HLD here contributes to the development of capacitive pulsed-power supplies and of pulsed magnets.
Metal processing with pulsed fields
The development of special-purpose pulsed-power supplies for various applications is a part of the technology concept of the HLD. Here, the HLD has emerged to a renowned partner for the development of pulsed current generators and field coils for science and industry. In a project which is funded by the state of Saxony and the EU via the European Fund for Regional Development, HLD and a partner, the Fraunhofer Institute for Material and Beam Technology (IWS) Dresden, develop a next-generation pulsed-power generator suitable for industry which will be used for electromagnetic forming, joining, and welding of hard-metallic work pieces.
The world's biggest capacitor bank
To achieve a field of 100 Tesla, an electromagnetic energy of 50 MJ and a peak current of 100 kA is needed. The most modern and most efficient way to store this energy and pulsing it to the magnetic coil is to use a pulse-discharge capacitor bank. .
With a single push of a button you can release the energy that would be released during braking of a diesel engine of 150 km / h to 0 km / hour, in an incredibly short period of a few hundred milliseconds.
This world's most efficient condenser system is composed of 20 modules, which provide energy from 0.9 to 2.9 MJ. It allows you to dine with coils up to four coaxial sections which can be operated with different energies and pulse lengths.
