Nal Scintillation Detector (Size : 1 “x1” Flat Type)
NUCLEONIX Scintillation Detector (1”x1” – Flat Type) SD151 is designed to be used with Gamma Ray Spectrometer (Integral) Type GR612 or modular system Type GR611M or its equivalent unit.
The integral assembly consists of NaI (Tl) crystal size 1”x1”, integrally coupled to a 11/2 inch bialkali phototube with mu-metal magnetic / light shield. The crystal and the photomultiplier tube are housed in an aluminium container.
The assembly is connected to a solid state Pre-amplifier PA311 of NUCLEONIX make. Connectors are provided on Pre-amplifier for EHT, low voltage and signal output. The complete Scintillation Detector can be housed in a Lead Shield. The pre-amplifier is designed to suit a wide range of standard Scintillation detectors.
