Typical activities of the research groups at HIL GDR studies γ-γ in-beam spectroscopy Life time measurements (e.g. with DSA method) Multiple Coulomb excitation studies On-line β internal conversion spectroscopy Reactions with light ions Fusion barrier height distribution studies Biological interactions of high LET radiation studies Irradiations of solid state materials with heavy ions Semiconductor detectors development and tests
About hours of beam-on-target time in 2006 was used by internatio- nal users. All projects performed at HIL are evaluated by international Program Advisory Committee.
Other facilities Heavy Ion Laboratory supports experimental groups with: a mechanical workshop an electronic workshop a data acquisition service a laboratory for HPGe detector annealing process. In Heavy Ion Laboratory there are available: 10 guest rooms with a kitchen and a meeting room a conference room for 120 persons.
