Radiation Detectors Laboratory (LabRad)
The Radiation Detectors Laboratory (LabRad) is dedicated to the characterization of semiconductor radiation detectors and radiation detection systems. The laboratory is a radiation facility licensed to work with sealed radiation sources by the Spanish Nuclear Security Council (CSN).
Techniques:
- Electrical test of semiconductor radiation detectors and other microelectronic devices in probe station with controlled temperature
- Charge collection efficiency measurements with low activity sealed radiation sources
- Transient Current Technique (TCT) characterization of the response of semiconductor detectors to radiation
- Test of electronic systems related to radiation detectors and their readou
