Semiconductor detector conditioning

Care should be taken not to exceed the ambient temperature range specified by the manufacturer. Moisture, corrosive gases and liquids, and conductive dust can all have adverse effects on a system that is not adequately protected.

Incorrect voltage or frequency may cause a malfunction or damage to device. Detector can be affected by rapid changes of voltage. Follow manufacturer's specifications about the rate of rising the voltage. Detector could be damaged if polarity of applied voltages is incorrect.

Electrical noise must be maintained as low as possible. Precautions should be taken to avoid electrical disturbances (electrical noise, electrostatic discharges, sags, swells, surges, short and long term outages). Proper wiring practice will minimize the influence of electrical noise, which may cause malfunction of equipment.

The cooling of the semiconductor detector (electrical or using liquid nitrogen) should be guaranteed all the time during detector operation. In the specific case of liquid nitrogen, the accompanied dewar should be refilled periodically. It is necessary to take into consideration that the lack (or unexpected absence) of liquid nitrogen can cause abnormal functioning (or damage) to the semiconductor detector.
