Overview

The 781 MCA family is composed by compact, stand-alone Dual or Quad independent 16k digital MCA, available in Desktop and NIM form factors.

They are designed for high energy resolution semiconductor detectors, like HPGe and Silicon detectors with resistive feedback Charge Sensitive Preamplifiers.

The 781 MCA family integrates advanced firmware algorithms operating Digital Pulse Processing for Pulse Height Analysis (PHA). The processing algorithms can be easily adapted to different detectors and application ensuring effective data analysis even at high count rates. It provides advanced tools for configuring baseline restoration and pile-up rejection. Thanks to the multiple input simultaneous acquisition, the module is able to manage coincidence and anti-coincidence logic between detectors, allowing the user, for example, to easily take advantage of background rejection or anti-Compton techniques.

These MCAs can provide at the same time energy, time stamp and the digitized pulse in a configurable time window (e.g. including the rising edge region) in order to perform further oine analysis. Acquisition settings and basic mathematical analysis are performed through the new MCAnalyzer software, providing energy spectra with up to 16k channels, which can be exported and imported in ASCII or N42.42 compliant files. CAEN provides moreover drivers for the supported communication interfaces, configuration software tools, C and LabVIEW libraries (CAENComm, CAENDigitizer, CAENDPP), demo applications and utilities.
