Function of bias resistor in semiconductor detector

Click For Summary
SUMMARY

The bias resistor (RB) in a CdZnTe radiation detector setup is crucial for applying the detector bias voltage. It regulates the voltage across the detector, ensuring optimal performance and stability. Selecting an appropriate bias resistor involves understanding the specific voltage requirements outlined in resources such as the NSS short course and the Eurorad detector specifications. Proper selection directly impacts the detector's sensitivity and response time.
