The DT5770 is a compact portable 16k Digital MCA for Gamma Spectroscopy, integrating analog front-end with programmable gain and possible AC coupling. It is ideally suited for high energy resolution semiconductor detectors, like HPGe and Silicon, connected to a Charge Sensitive Preamplifier (CSP). The unit can also properly operate directly connected to a PMT with inorganic scintillators (e.g. Nal or Csl scintillators), provided exponential pulse shape and decay time above 200 ns.

The DT5770 is equipped with a FPGA featuring the real-time Digital Pulse Processing for Pulse Height Analysis (PHA) making the module a data acquisition system for Nuclear Physics and other applications involving radiation detection. The DT5770 houses USB 2.0 and Ethernet interfaces. The Module is either powered by USB, or by external AC/DC power supply, or Power over Ethernet (optional).

Two ways of operation are foreseen:

pdf "Pulse Height Analysis (PHA)": pulse height histogram (1k-2k- 4k-8k-16k) built at board level
pdf "Oscilloscope": input and internal filters waveforms

106 W x 38 H x 128 L mm³ (without connectors)
106 W x 38 H x 150 L mm³ (including connectors)
PHA settings, acquisition and mathematical analysis are performed through the new MC² Analyzer, providing out energy and time spectra in ASCII or N42.42 compliant files.

CAEN provides moreover drivers for the supported communication links, DT5770 Upgrader tool and C libraries (CAENDPP library)
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 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.
