Description

The first main task of PTB within the UHDpulse project was to establish reference UHPDR electron beam. In this aim, the PTB research accelerator has been optimised to generate two 20 MeV reference beams which have been characterised along with the development of a Monte Carlo beam model enabling a third beam set-up for a total dose per pulse range from 0.1 Gy to 16 Gy per pulse. The second main task of PTB was to establish the PTB water calorimeter as primary standard. In this aim, the calculation of the required correction factors has been carried on using thermal simulations and Monte Carlo simulations. Finally, the absorbed dose measurements using the PTB water calorimeter has been compared to the primary standard used at METAS, Fricke dosimetry, for validation purposes using mailed alanine dosimeters as transfer dosimeters with the collaboration of NRC.
