MCA-Base OEM
Single-Channel MCA with PMT High-Voltage Supply

MCA-Base: USB-Powered MCA + HV-generator

The MCA-base consists of a an eMorpho multichannel analyser and an integrated high voltage generator and divider to power the photomultiplier (PMT). It plugs directly onto the PMT and can be powered and controlled via USB.

The high voltage divider can deliver 50 µA DC current and 10 mA pulse current to the PMT anode while maintaining excellent gain stability.
The device is sealed and specified over a temperature range of -15°C to +60°C.
