Together with a detector, the MCABase are complete spectrometer with integrated bias supply and preamplifier for PMT based detectors. It may be used for gamma-ray spectroscopy applications with NaI, CeBr, LaBr, SrI2 or similar scintillation detectors.
The MCABase modules are suitable for detectors with 14-pin (standard version) or 12-pin photomultiplier tubes like the Hamamatsu R6231, R1306 (Jedec B14) or R9420, 9102B, XP2060B (Jedec B12).
