Operating principle

 

 

 

 

 

 

 

 

 

 

Added with bias high voltage, the CZT crystal will generate an inner electric field. An incident ray of X/γ-ray generate electron-hole pairs. Then the low noise charge sensitive preamplifier will collect and lead them into shaping circuit. Then you will get Gaussian pulse signal. And with shifting signals function in it, the detector module can cover both low and high dose ratio radiation field.
