The 780 MCA family is composed by compact, stand-alone dual digital 16k MCA with integrated HV & Preamplifier Power Supply, available in desktop and NIM from factors. They are designed for high energy resolution semiconductor detectors, like HPGe and Silicon detectors with resistive feedback Charge Sensitive Preamplifiers.

The 780 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, pile-up rejection. Thanks to the two input simultaneous acquisition, the modules are 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 may 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 offline analysis. Acquisition settings and mathematical analysis are performed through the MC2Analyzer software, providing energy spectra with up to 16k channels, which can be exported and imported in ASCII or N42.42 compliant files. CAEN further provides drivers for the supported communication interfaces; configuration software tools, C and LabVIEW libraries (CAENComm, CAENDigitzer, CAENDPP), demo applications and utilities.

The high voltage supply channel can be ordered in three different versions to meet detector requirements: rated up to ±5 kV/300 μA for high purity germanium detectors, ±4 kV/3 mA (limited to 4 W) for scintillation detectors and ±500 V/3 mA for silicon and diamond detectors.

PHA settings, acquisition and mathematical analysis are performed through the new MC² Analyzer software, providing out energy and time spectra in ASCII or N42.42 compliant files.

CAEN provides moreover drivers for the supported communication links, configuration software tools C and LabVIEW libraries (CAENComm, CAENDigitzer, CAENDPP), demo applications and utilities.
MC² Analyzer (MC²A)
Digital MCA Data Acquisition and Analysis Software
MC2A is a software specifically designed to manage CAEN Digital MCA (DT5770, γ stream, Hexagon and 780/781 family) as well as CAEN digitizers running DPP-PHA (Digital Pulse Processing for the Pulse Height Analysis) firmware, like 724, 725 or 730 family.

It allows the user to set the relevant parameters, to manage the HV channels configuration (x780, γ stream and Hexagon only), to collect the spectra and perform mathematical analysis on them, like energy calibration, peak search, background subtraction, peak fitting, etc.

It is designed with multi-channel, multi-board capabilities: it can handle several boards and manage the data acquisition from each of them at the same time.
