Abstract

The intrinsic efficiency of some 100 mm-thick slightly tapered CsI(Tl)crystals of the Faziaarray irradiated with protons has been measured exploiting the beams delivered by the synchrotron of the CNAO medical facility in Pavia. The kinetic energies of protons ranged from about 70 MeV up to 190 MeV. A similar study has been already performed by our group in the past for the same CsI(Tl)detectors in a collimated configuration. Here we extend the investigation to crystals with fully exposed entrance surface mounted in a complete Faziablock, in realistic experimental conditions. The obtained results are compared with dedicated GEANT4simulations. A good agreement has been found, confirming both the quality of the model description and the need to take into account the measured efficiency decrease in a real physics experiment.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
