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.
