Unique Sell - MCA ver.4 Nuclear Pioneer Gamma Spectrometer Electronic Module (assembled unit, scintillation probe not included) for DIY Gamma Spectroscopy project Nuclear Pioneer MCA Multichannel Analyzer Electronic Module assembled into enclosure. Include internally installed rechargable 2000mAh LiPo battery, CR2032 battery, Tiny Geiger counter and microSD. The MCA can work as a robust Gamma Spectrometer and as a Scintillation Counter Survey Meter. It has high count rate performance for spectrum mode and for scintillation search mode. The board has regulated high voltage circuit with adjustable output of 600V-1000V postive polarity that allows to connect a NaI(Tl) probe with BNC cable. Probes with high impedance divider of ~50Meg-120Meg are supported. The pulse pre-amplifier set for an optimal gain, however you can re-adjust it if required. The MCA can detect Gaussian shape peaks in real-time. It has small library of radionuclides for hobby Gamma Spectroscopy. The counter calculate energy compensated doserate or can subtract previously saved background data file from the spectrum in real-time during spectrum acquisition. To use the MCA you need to add NaI(Tl) scintillation probe and BNC cable, Calibration of the hardware and the software is required to set a correct gain for your NaI(Tl) probe. Nuclear Pioneer MCA can work with small and big volume NaI(Tl) crystals probes. You may need to re-adjust high voltage with small screwdriver after connecting the probe to set the total gain of the analog circuit. Pulse pre-amplifier circuit is set for optimal pulse shape and gain, however in some circumstance you may need to re-adjust the pre-amplifier gain ratio (manual is included). Channel-to-Energy scale polynomial calibration can be done with selecting a scheme from the menu and simple picking 3-points on spectrum. Automatic calibration of CPS standard deviation for scintillation mode can be triggered from the menu. Other software settings are changed through serial port commands in UART-USB terminal or BLE terminal from the smartphone. The MCA has full speed 12MBit/sec USB port for calibration or spectrum data download. Any further firmware updates can be done with friendly Arduino Teensy bootloader by connecting USB cable and selecting ready hex file to upload. The module include internally installed tiny SBM-21 type sensor. The GM sensor CPS readings can be used in scintillation mode during prospecting in high radiation areas.

Please avoid shorting high voltage on BNC socket and do not use hot plug of the probe because HV arcing across the BNC jack can ruin sensitive electronics. Recommended BNC cable part number CT2942-100. Recommended BNC jack for probe is 31-221-RFX.
