Canberra Osprey w/Bicron 3x3 Scintillation Detectors

$12,500 / ea

Slightly used for about 5 months on a field project. Kept in lab for counting soil samples.

The Osprey® is a high-performance, fully integratedmulti-channel analyzer (MCA) tube base that contains everything needed to support scintillation spectrometry. Designed for both laboratory and field use, this one compact unit contains a high-voltage power supply (HVPS), preamplifier and a full-featured digital MCA. Osprey can be controlled through either USB or Ethernet with no need to purchase two separate units - an industry first. USB or Ethernet, there is only one cable connecting the Osprey to the control and data acquisition system. With software, shielding & detector  stands and computers for both systems. Easy to transport.

Canberra High-purity Germanium (HPGe) Detector Model GC/S2623


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. Under reverse bias, an electric field extends across the intrinsic or depleted region. 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.
