SCGS-01 with 2" scintillation probe

Scintillix gamma spectrometry system SCGS-01 is intended for use in low level gamma counting, thus is suitable for educational purposes in school and university laboratories, in comunity based laboratories and for gamma spectrometry enthusiasts.

Scintillix system consists of 2" scintillation probe containing thallium dopped sodium iodide NaI(Tl) inorganic scintillator optically coupled to 9-stage high PHR photomultiplier tube (PMT) operated up to 1 kV. Scintillation probe contains resistive divider for PMT with 58 MOhm total resistivity and charge sensitive amplifier (CSA) followed with pulse shaper (PS). Probe is connected via cable to the control unit. Control unit can be connected to a PC by means of USB cable or to other device (e.g. oscilloscope) via BNC connector on the rear panel.
