Slim Spectrometric Detection Probe

SDP 311
SDP 311/C

"Slim" Spectrometric Detection Probes are miniature gamma-ray detection devices. Spectrometric detection probe SDP 311 and counting detection probe SDP 311/C are available.

The detection probes consist of detector and charge sensitive preamplifier placed inside of a thin rectangular case. The SDP 311 contains CdZnTe quasi-hemispherical detector, the SDP 311/C contains CdTe or CdZnTe planar counting grade detector.

These probes have been especially designed for application in a very narrow locations. Distinctive peculiarity of the SDP 311 is a very small thickness, only 4 mm. These probes also can be used as a single element of a multi-element detectors array.

Features

Very small thickness and weight
High energy resolution
Room temperature operation
High countrate capability
Small consumption power

Applications

Nuclear spent fuel verification
Nuclear waste treatment facilities
Multielement detectors array
