NaI(TI) scintillator detectors

Model EPHP Series Sodium Iodide Scintillation Detector is a high efficiency detector featuring a NaI(TI) crystal with typical dimensions of 1.0"x1.0", 1.5"x1.5", 2.0"x2.0" and 3.0"x3.0", included a photomultiplier tube(PMT), an internal magnetic/light shield, a high voltage power supply(HVPS), stabilization electronics, preamplifier and a 4-pin proprietary connector.

The signal from PMTs is processed with a hybrid low power pre-amplifier plus a spectroscopic shaping amplifier system, the output pluses can be directly fed into the MCA, the low power consumption make the scintillation probe ideally suited for use with portable, battery operated multi-channel analyzer systems.
