MCABase MCA for Scintillation Detectors

Compact multichannel analyser with integrated bias supply and preamplifier, mounted directly on PMT-based scintillation detectors.

The MCABase may be used for gamma-ray spectroscopy with NaI, CeBr, LaBr, SrI₂ or similar scintillation detectors. It has a solid anodised aluminium body and an integrated temperature sensor.

  • Together with a detector, a complete spectrometer
  • Up to 4k channel resolution and throughput above 100000 cps
  • Very low power consumption of 0.4 W
  • Bias supply 0 V to 1000 V, software controlled
  • Ethernet, USB or RS485 interface versions
