Nal Scintillation Detector (Size : 3″x3″ Flat Type) [ Type No.: SD 153F ]
Technical Data
NUCLEONIX Scintillation Detector (3”x3” – Well Type) SD153 is designed to be used with Gammaray Spectrometer GR611M (Modular) or its equivalent unit.The integral assembly consists of NaI (Tl) crystal size 3”x3”, integrally coupled to a 3 inch bialkali phototube with mu-metal magnetic / light shield. The crystal and the photomultiplier tube are housed in an aluminium container.
The integral assembly consists of NaI (Tl) crystal size 2”x2”, integrally couThe 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.
