Abstract

In this work, a calorimetric system based on two graphite cores for absorbed dose measurements is described. The calorimeter also serves to correct the non-proportional (quenched) response in densely ionizing beams observed in scintillators. The system is designed for high-intensity scanning proton beams, where the deposition of each spot can be monitored by a fibre-coupled plastic scintillation detector (PSD). The graphite core can be replaced by a hollow replica of the core accommodating the PSD, in principle allowing the quenched PSD response to be corrected relative to the small graphite core under nominally identical radiation conditions. This work focuses on the design of the calorimetric system to minimize the heat losses during irradiations. The operation of two graphite cores is demonstrated to be reproducible within
