Workshop on Positron Annihilation Spectroscopy
| Date | 19.10.2010, seminar room 120/018, Forschungszentrum Dresden-Rossendorf |
| Venue | Forschungszentrum Dresden-Rossendorf, Lecture Hall Building 120 |
| Scope and Goals | Strategical development of positron annihilation spectroscopy at the FZD |
| Organizers | Andreas Wagner (FWK), K. Potzger (FWI) |
The intention is to combine the efforts of three institutes and external partners with the emphasis on a coherent strategy for the application of the various techniques based on positron annihilation spectroscopy (PAS).
At the FZD, four complementary techniques are available for PAS
- SPONSOR: source-based positron beam with energies up to 30 keV for depth-resolved defect concentration and characterization using Doppler-broadening spectroscopy.
- LT: source-based positron lifetime spectroscopy with LHe-cryostat
- GiPS: accelerator-based gamma-induced positron lifetime spectroscopy setup for bulk material and radioactive samples.
- MePS: accelerator-based mono-energetic positron source for depth-resolved defect concentration and characterization using Doppler-broadening spectroscopy.
The talks shall focus on the applicability of positron annihilation spectroscopy for the specific scientific issues.
