Description
The Photo Injector Test facility at DESY in Zeuthen (PITZ) can provide unique beam parameters regarding delivered dose and dose rate. With an average dose rate of up to 1E7 Gy/s and peak dose rates of up to 4E13 Gy/s, PITZ is fully capable of UHDR irradiation which should allow FLASH radiation therapy.
A completely new beamline exclusively for FLASH RT and biology experiments was built. One goal is to develop and test detectors which cover the whole range of dose rates. Additionally, there is the possibility for external users to test their detectors, bring their biological samples for irradiation and do joint experiments at PITZ!
First dosimetry experiments using Gafchromic films were done in air and in water. Dose rate linearity and limit tests of the films will be presented. Beam parameters like beam profile, dose depth profile in water, homogeneity and dark current will be shown.
