  • Compact portable 16k Digital MCA

  • Suited for high resolution Gamma Spectroscopy

  • Support continuous and pulsed reset preamplifiers

  • Software selectable coarse and fine gain

  • DB9 connector for preamplifier power supply

  • Features Pulse Height Analysis firmware for energy calculation

  • Different acquisition modes available: PHA and signal inspector for an easy setup and signal monitoring

  • USB and Ethernet communication interfaces

  • Supported by MC2Analyzer software GUI for configuration, acquisition, and data plotting

The CAEN Mod.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 powered by a provided external AC/DC power supply.

Two ways of operation are foreseen:

  • Pulse Height Analysis (PHA): pulse height histogram (1k-2k-4k-8k-16k) built at board level.

  • Oscilloscope: input and internal filters waveforms.

Software available

  • PHA settings, acquisition and basic mathematical analysis are performed through the MC² Analyzer software GUI (Windows only), providing energy 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).
