Investigations on BeO as a dosimeter material for hadron therapy

Hadron cancer-therapy with high-energetic heavy-ions (HI) as available at the SIS facility at GSI Darmstadt [1] as well as the research with beams stopped in biological material as realized at the UNILAC at GSI in general require the precise knowledge of the applied dose within less than 1% in most cases. Solid state detectors based on various materials read out via thermally stimulated light emission are often used to fulfil this task [2].
