Scintillator performances

CEA

The DETector Lab of CEA has developed state of the art X and gamma imagers which can be used to assess photodetectors for several applications.

- Large area CMOS backplanes which can be used to evaluate scintillator for medical X-rays in X ray facilities in the 20-160 kV range. Scintillator for PET application could be evaluate with digital SiPM and gamma source.

- Semiconductor photodetector could also be evaluated using gamma-ray spectrometric imagers in the 14 keV-1 MeV range.

Radio-luminescence

Temperature range: 10 to 320 K; irradiation by a Philips 2274 x-ray tube; RL emission detected by Jobin Yvon Spectrum One 3000 CCD in the 200-1100 nm spectral emission range.

Thermoluminescence:

Temperature range: 10-800 K (in two different apparatuses); irradiation by Machlett OEG50 x-ray tube (for measurements above room temperature) and by Philips 2274 x-ray tube (cryogenic measurements). TSL light detection by Jobin Yvon Spectrum One 3000 CCD (for cryogenic measurements, 200-1100 nm), Jobin Yvon Sympony CCD (or measurements above room temperature, 200-1100 nm), and EMI 9635QB photomultiplier (measurements above room temperature).
