Modular Pulse Processing Electronics

The Modular Pulse Processing Instrumentation is the interface between the experiment and the scientist. It extracts information from the detectors, allowing all data to be acquired and analysed.

CAEN provides a complete and ever increasing set of instrumentation, from Preamplifiers to Data Acquisition to Triggering Electronics and Logic Functions. Most of the instrumentation is available in the most popular standard form factors and bus protocols, such as VME, NIM, CAMAC and Desktop.
The Desktop is the stand alone form factor of the CAEN products. It provides the same performances of the other form factors and take the advantage of an easier and portable use, requiring no crates.

Open FPGA Digitizers

This is the CAEN new family of modern digitizers, that will improve all the features already present in the current line-up and bring new ones that will expand its capabilities on many areas. These new digitizers combine the same firmware along with a new wave recording software with enhanced capabilities, together with the OpenFPGA feature. Another plus is represented by the availability of a Linux-based embedded ARM processor. This allows to run a lite version of the operating system on board and, therefore, to take advantage of that environment for automatization of some function without needing a dedicated DAQ PC always connected to the digitizer.

CAEN Open FPGA Digitizers feature programmable Open FPGA, embedded ARM and significant architecture upgrades for improved performance:

  • Increase of acquisition memory buffer size: from SSRAM to DDR4;
  • Increased communication readout through 1/10 Gb Ethernet, USB 3.0;
  • More resources for DPP algorithms and support for Programmable Open FPGA;
  • Easier multi-board synchronization (clock and timing distribution);
