Scientific Applications

Application

Detection of Gamma-rays in nuclear energetics and environmental control, in industry and scientific research, in nuclear medicine and other applications when the user is dealing with small amount of sample and is willing to have better efficiency if to compare to regular Coaxial HPGe detectors.

Energy range from 20 keV to 10 MeV
Well materials: Aluminum
Thin “dead” layer to provide excellent efficiency
Built-in or Remote Preamplifier types are available depending on application
Almost 4π geometry measurement
Low instrument background
High energy rate up to 200000 MeV/s
Excellent peak symmetry & high resolution
HV supply protection if detector is warm
High count rate indicator
Variable cryostat design modifications
