LIQUID NITROGEN COOLED DETECTOR FOR GAMMA AND X RAYS SPECTROSCOPY

Home » Products » Detectors » Portable HPGe Detectors

DESCRIPTION:

Germanium detectors are semiconductor diodes having a p-i-n structure in which the intrinsic (I) region is sensitive to ionizing radiation, particularly x rays and gamma rays.
When photons interact with the material within the depleted volume of a detector, charge carriers (holes and electrons) are produced and are swept by the electric field to the P and N electrodes. This charge, which is in proportion to the energy deposited in the detector by the incoming photon, is converted into a voltage pulse by an integral charge sensitive preamplifier.
Because germanium has relatively low band gap, these detectors must be cooled with Liquid nitrogen (temperature of 77 °K)

APPLICATION:

Detection, accumulation and processing of gamma spectra in field and industry conditions where small dimensions and weight of spectrometer are important
