I would like to represent my development of gamma spectrometer:
Amateur based RIID gamma spectrometer for spectrum acquisition, isotope identification and activity calculation.
Supports NaI(Tl) or CsI(Tl) crystals 63x63, 51x51, 40x40, 25x25, 10x40
Isotope Library Include: Cs-137, Ra-226, Th-232, Bi-214, Ba-133, Am-241, Lu-177, K-40, Co-60, U-235
Activity calculator for: Cs-137, Ra-226, Ba-133, Am-241
- 12-bit 4096 channels ADC
TFT LCD 3.5” 480x320 with adjustable backlight level
Rotary Encoder for controls
600V-1000V adjustable high voltage for photomultiplier probe positive polarity
400V or 500V high voltage for an internal Geiger Counter
Adjustable gain & pulse shape pre-amplifier for an external photomultiplier probe
Gamma Spectrometer Mode (tested up to 10.000 CPS)
Scintillation Counter Mode with PMT and GM Sensor
Easy Channel to Energy calibration with selectable scheme and channels pick
Real time background subtract mode for gamma spectrometer
Real time gaussian peak detection
Real time activity calculation (beta since 4.07 firmware)
Linear or Logarithmic spectrum viewer
Energy compensated dose rate
0.30 uSv/h doserate alert and 2-sigma CPS alert in scint.mode
CPS standard deviation calibration for scint.mode
Mute / Alert / Clicking in scint.mode
Spectrum LCD zoom 512-4096 channels
Micro SD card for data storage
RTC (require CR2032 battery for date and time keeping)
Internal temperature sensor
Bluetooth BLE module (optional)
12Mbit USB port for programming, calibration or data transfer
Easy firmware update via USB and friendly bootloader
