Localization of the scintillation detectors manufacturing process has many benefits because of the high detection efficiency of the detectors, user-friendly, and consistent with general research objectives. Using a photodiode instead of a photomultiplier tube (PMT) allows saving energy, shortening the detector volume, and removing high voltage power supply and amplifier. The combination of CsI(Tl) scintillator, avalanche photodiode, charge sensitive preamplifier, wide range amplifier, and power supply system has been integrated into the detector. This study presents new results in manufacturing a home-made scintillation detector using avalanche photodiode. The detectors of this type can be used in hospitals, in the nuclear laboratory of universities for the students training, etc.
