Operation principle
Added with bias high voltage, the CZT crystal will generate an inner electric field. An incident ray of X/γ-ray generate charged particles in the crystal. Then the low noise charge sensitive preamplifier will collect those particles and convert them into exponential decay signals. Gaussian pulse signal will forming after those signals pass through CR-(RC)n shaping circuit.
