Scintillation detectors REGISTRATION time of arrival of ionizing particles with picosecond ACCURACY

摘要

The utility model relates to the registration of ionizing particles, such as fast electrons and positrons, gamma rays with an energy of 500 keV to 10 MeV with a high time resolution, namely to scintillation detectors and is designed for detecting particles in high energy physics with high flow and in medical equipment such as positron emission tomography TOF registration. The technical result is improvement in the accuracy of measurement points enter (register) of the ionizing particle to 10 picoseconds. Scintillation detector for registration of ionizing particles and gamma rays with energies of 500 keV to 10 MeV with a time resolution of less than 100 picoseconds comprises a scintillation crystal plate glass filter and a silicon photomultiplier. Scintillating crystal plate of thickness 1 mm made of pure CsI and is provided with a light-scattering coating except the part of the surface which is in optical contact with a glass filter. Filter configured to pass CsI ultrafast radiation with a wavelength greater than 500 nm and with the possibility of a slower absorption of radiation with wavelengths shorter than 450 nm. A silicon photomultiplier is in optical contact with the filter. 4 ZP f ly-1-yl.
