SIGMA scintillator detectors

When you need a fast and light detector.

SIGMA a family of scintillator-based detectors

CsI(Tl) thallium activated caesium iodide scintillator radiation detector

Our SIGMA range of CsI(Tl) thallium activated caesium iodide scintillator radiation detector products replaces conventional photomultiplier technology with state of the art SiPMs. These gamma-ray detectors offer up to 32.8 cm3 of detection volume, delivered in a package providing significant benefits in cost, size, weight, power consumption and temperature stability.

CsI(Tl) has a light output of 54 photons/keV and is one of the brightest scintillators known, as well as good gamma-ray photon stopping power which makes CsI(Tl) well suited for gamma radiation detection. The crystal itself is robust and can survive in handheld portable detectors and operate at room temperature.

The SIGMA range interfaces directly with Kromek’s KSpect or MultiSpect gamma spectroscopy software.
