1.5" x 1.5" NaI(Tl) Detector
This detector is a great general purpose detector, it has a 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 neatly capped off with an aluminium cap and silver plated BNC connector. Surface finished in a hard wearing radiant blue anodizing, you would have to admit that it's also pretty cool.
We recommend this detector for use with the GS-1100 range of drivers.
This detector is built by Bee Research from quality new components.
