NaI(Tl) Gamma Scintillation Detector 1.5" x 1.5" Crystal    

This detector is a great general purpose detector, it has an encapsulated  38 x 38 mm Sodium Iodide crystal, coupled to a PMT with integral voltage divider.

The whole package is housed in a spun aluminium housing and finished in pearl white powder coating.

The detector is supplied with an SHV male connector, compatible with the GS-USB-PRO, but can be supplied with a HV-BNC if required.

We recommend this detector for use with the GS-USB-PRO spectrometer.

This detector is built by Bee Research from quality new components.
