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 coincident and multiplicity counting, security and safeguards, mixed-field assay and imaging.
The system can function with or without a host PC via an Ethernet connection. The PC connection affords the use of the PC-based Graphical User Interface (GUI) where system configuration, auto-calibration and the ability to analyse PSD and PHS data can be performed. When functioning independently (i.e. without a host PC) separate digital TTL outputs are available for analysis using secondary diagnostic instrumentation such as a coincident counter. The neutron and gamma TTL outputs toggle according to the event type, have a high real-time throughput, and are time correlated with the incident event.
An auto-calibration feature provides a convenient means for response matching detectors by automatically fine tuning the dedicated HV supplies to align the PHS spectra obtained using a calibration source (typically Cs-137).
The MFAx4.3 cluster is housed in a convenient carry case (PeliTM Storm iM2750 Case) with built-in 28 V AC-DC power supply module (400 W).
