Energy resolution of CsI (TL)‎ crystal coupled with PIN photodiode

الملخص EN

The emission spectrum of the CsI (Tl) scintillation crystal does not match well with the spectrum sensitivity of the standard photo-multiplier.

This is the main handicap limiting the use of this crystal for radiation detection.

However, the production of the new photodiodes, with better characteristics, is likely to be a good candidate as a readout device for this crystal.

One way to investigate this possibility is to study the energy resolution of the CsI (Tl) crystal coupled with a new large area PIN photodiode.

The purpose of this paper is to determine the different contributions affecting this resolution including that of the readout device.
