Detectors For Ionizing Radiation

With the X-series First Sensor export, manufacture & supply detectors for Lonizing radiation including X-or gamma rays but also alpha or beta particle radiation from Berlin, Berlin, Germany. First Sensor can adopt its radiation detector technology to each individual application.
Solid state detectors provide a reliable and compact solution for radiation measurement. First Sensor offers both scintillator and direct absorption based detectors. While scintillator detectors use the conversion of nuclear radiation into visible light by luminescence of a scintillator crystal such as CsI or LYSO the detectors based on direct absorption use the interaction of silicon with radiation directly to measure a photocurrent. Especially for low energy X-rays and particle radiation direct absorption is a convenient solution.

Our detectors are available from 0.2mmA active area up to 100mmA and more. Our X100-7 detectors are based on 100mmA active area photodiodes and are available with CsI:Tl scintillator crystals of 8mm and 4mm height and a special scintillator coating process that both maximizes the detection performance and enables cost-effective mass production.
