UHDpulse - Metrology for Advanced Radiotherapy using beams with Ultra-High
Pulse Dose Rates is a European project aimed at developing novel dosimetry
standards, as well as improving existing ones, for FLASH radiotherapy, very
high energy electrons radiotherapy, and laser-driven medical accelerators.
Within the scope of this project, Thermoluminescence (TL) and Optically
Stimulated Luminescence (OSL) detectors are used to measure stray radiation
fields. Experiments performed with conventional pulsed particle-beams allow to
characterize the dosimeters in known and controllable radiation fields. In
turn, this allows to develop models and predict their behavior in complex
radiation fields, such as those at laser-driven and FLASH facilities. TL and
OSL detectors were irradiated at the Microtron MT25 electron accelerator in
Prague, Czech Republic. GAFChromicTM films and plastic nuclear track detectors
were used to study the beam profile and the neutron background respectively.
The responses of the different detector to the pulsed mixed radiation fields of
the Microtron MT25 are compared among each other and presented in this paper
