PMT Photomultiplier Amplifier Module for DIY Gamma Spectrometry
PMT amplifier module for 2-Wire configuration probes. Output pulse shape and decay time are compatible with audio-card requirements for amateur Gamma Spectroscopy on computer. The amplifier is installed with additional 1Meg. load resistor between high voltage power supply and BNC jack for PMT probe. Output SMA jack allows to use shielded cable for signal patch between spectroscopy setup and audio-card input. Example wiring diagram is included.
