If, for any reason, the detector warms up enough that the HV shuts down (e.g., loss of LN2) or if for any other reason
the detector warms for more than 10 minutes, it should be warmed to room temperature before re-cooling.
Typical
warm-up time for most detectors is 24 hours. For higher-efficiency detectors (>70%), allow 36 hours warmup time.
To determine if the detector is cool enough to be operated, attempt to turn on the detector bias (high voltage). If the
detector is still too warm, the bias shutdown circuit will prevent high voltage from being applied. If the detector is cold
enough, the bias will turn on. Be sure to allow the voltage to stabilize 15–30 minutes before taking data with an HPGe
detector.
If the detector remains in shutdown mode after 36 hours of continuous cooling, contact your local ORTEC
representative or our service center.
