ORTEC offers a wide range of HPGe radiation detector solutions which cover energies for X-rays in the few hundred electron volts (eV) range up to gamma rays in the 10 MeV and above range. These detectors are manufactured using high purity germanium (HPGe) of both P- and N-type. All detectors in these two classes are cryogenically cooled, using either liquid nitrogen or electro-mechanical coolers.
