GAMMA SPECTROSCOPY & COMPTON EFFECT

This setup with internal pre-amplifier allows direct connection to scintillation detectors. The bipolar amplifier includes polarity selection and multiple shaping times when using different types of detectors with external pre-amplifiers. Upper and lower level discriminators may be set for rejection of unwanted signals. The high voltage supply is rated to +2048V for use with scintillation or proportional detectors. Optional polarity selection is available for use with detectors requiring negative bias. A pre-amplifier power connector (±12V) is included for use with our model PA-1 external pre-amplifier. A 10µsec fixed conversion ADC allows high throughput with dead-time correction. Input selection for pre-amplifier, amplifier or ADC is controlled through computer. A background buffer is included for storing a spectrum when background subtraction, factional spectrum stripping or overlay is required. Presets include real time, live time and ROI integral. UCS30 may be operated as a multichannel scaler for time correlated studies e.g. half-life decay. A special mossbauer mode is included with MSB output for synchronization of the drive circuit. X-ray mapping may be performed with the optional ROI output. An auto-calibrate mode is provided that automatically sets the HV and amplifier gain to 1 keV/channel using a Cs-137 source.
