Both PAM1002 and PAM0502 are single channel counting module based on CZT detector.They integrated CZT detectors,which sizes are 10x10x2mm³, 5x5x2mm³ or others, high gain charge sensitive amplifier and SK shaping circuit.
1. Specification of Single Photon Channel Counting Module
|Dose rate range||0.1uSv/h~1.5mSv/h|
|Time to peak||440ns|
|Falling edge time||1.7us|
2. SPC Counting Module 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.
3. Applications of SPC Counting Module
■ X-ray detection
■ Probe for radiation dose rate meter
■ Portable counting instruments
