DMCA-U Digital Multichannel Analyzer

DMCA-U is a digital multichannel analyzer adopting 14-pin photomultiplier tube (PMT) base, which can be used for gamma-ray spectrum readout of PMT scintillation detectors including NaI and LaBr detector, etc. DMCA-U integrates modules such as miniaturized preamplifier, high-voltage module for detector (0 to+1100V), digital gain adjustment, high voltage divider module, temperature acquisition module, and digital signal processing module based on high-speed analog-to-digital converter. The multichannel analyzer adopts digital pulse shaping algorithm, and arithmetic logic covering baseline restoration, pile up rejection, peak stabilization, etc. The internal parameters can be modified as needed through software to adapt to different scenarios for gamma spectrum measurement.
