Evaluation of Measuring Techniques to Determine the Applied Dose of Ultra-High Energy Electorn Beams in Cell Samples for FLASH Therapy — •Leonardo Thome, Klaus Desch, Daniel Elsner, Dennis Proft, and Kelly Grunwald — Physikalisches Institut der Universität Bonn

The electron accelerator facility ELSA delivers up to 3.2 GeV electrons. Ultra-high energy electrons (UHEE) in short pulses of microseconds up to milliseconds (FLASH) are used to investigate the effect of UHEE on tumor cells. This may enable highly efficient treatment of deep-seated tumors due to the FLASH effect. Currently, in a preliminary setting the Booster-Synchrotron is used to deliver electrons of 1.2 GeV energy, to irradiate cell samples placed in a water phantom. A precise dose determination is necessary to monitor the efficacy of the biological effect. Therefore, the usability of different detector types for a precise dose determination is evaluated.
