Response from inorganic scintillation screens induced by high energetic ions

Inorganic scintillation screens were irradiated with swift heavy ion beams at GSI accelator facility, using protons up to Uranium ions as projectiles. Beams were extracted from the synchrotron SIS18 with high energy (≈300 MeV/u) in slow and fast extraction mode. During irradiation the scintillation response of the screens was recorded by two different optical setups simultaneously to investigate the light output, profile characteristics and emission spectra. In principle fast extracted beams induce lower light output than slow extracted beams. The output per deposited energy shows a decreasing dependency with respect of the atomic number. Emission spectra showed no significant defects of the materials, neither at irradiation with increasing beam intensity nor during long time irradiation.
