Detecting Ionizing Radiation with the Series X
Alpha, beta, gamma and X-ray radiation can be detected using silicon PIN photodiodes either indirectly via the measurement of the luminescence radiation of a scintillation crystal or directly via the absorption in the crystal lattice. The Series X from First Sensor has optimized silicon PIN photodiodes, which form broad, fully depleted space-charge regions even at low reverse voltages so as to ensure maximum absorption of radiation. For high-energy radiation, First Sensor offers detectors with a CsI:TI scintillation crystal.
Special Features
Very low capacitance levels
Very low dark current signals
Minimal series resistance at full depletion
Features
Very compact design
Two-stage charge amplifier, filter amplifier and comparator
High sensitivity for Cs137
