Yes, NaI(Tl) scintillation detectors can be temperature stabilized, and stabilization is important for maintaining accurate energy calibration. NaI(Tl) crystals exhibit a light output that varies with temperature — approximately -0.2% to -0.3% per degree Celsius — which means the detector’s energy calibration will drift as ambient temperature changes. Common stabilization approaches include digital gain stabilization electronics that automatically compensate for temperature-induced gain shifts, thermoelectric coolers (TECs) for active temperature regulation in controlled environments, and thermally insulated housings for passive stabilization in field deployments. Berkeley Nucleonics offers detectors with built-in digital gain stabilization for applications where temperature fluctuations are unavoidable.
