Advatech CZT radiation detectors
Advatech offers a broad range of CZT radiation detectors (Overview of CZT Detectors) - both counter and spectroscopy grade, available as sensors, assemblies and probes through to complete instruments. Standard products and bespoke configurations available. A range of Quasi-hemispherical Detectors are available.(What are Quasi-hemispherical Detectors?)
CZT is a room temperature semiconductor that directly converts radiation (x-ray or gamma-ray) photons into electrons and can produce >10⁶ photons/second/mm² with an effective Z of >49 and density 5.8g/cm³.
