This extremely versatile digital analyser offers a complete real-time Pulse Shape Discrimination (PSD) solution for scintillation detectors with Multi-Channel Analyser (MCA) Pulse Height Spectra (PHS) analysis. The analyser has applications in coincidence and multiplicity counting, security and safeguards, mixed-field assay and imaging.
The analyser can function with or without a host PC. In stand-alone mode, separate digital TTL outputs for gamma and neutron events are provided for analysis using secondary instrumentation such as a coincidence counter. These outputs have a high real-time throughput, and are synchronised in time with the incident event.
Connection to a PC or tablet via either Ethernet or Wi-Fi enables the use of a Graphical User Interface (GUI) where system configuration, auto-calibration and the analysis of PSD and PHS data can be performed. The GUI supports touch screen functionality and scales appropriately to the number of MFA devices detected on the network.
The auto-calibration feature provides a convenient means for response matching detectors by automatically fine tuning the dedicated HV supply to align the PHS spectrum obtained using a calibration source (typically Cs-137).
