Overview
The CAEN Mod. DT5724 is a digitizer able to record waveforms along with performing advanced algorithms for online digital pulse processing (DPP) of pulse height analysis and dynamic acquisition window.
Data is read by a Flash ADC, 14-bit resolution and 100 MS/s sampling rate, which is well suited for high-resolution detectors as Silicon, HPGe or inorganic scintillators like NaI or CsI coupled with Charge Sensitive Preamplifiers. In the waveform recording mode, algorithms of zero suppression are also implemented to reduce the data throughput. The acquisition can be channel independent and it is possible to make coincidence/anti-coincidence logic among different channels and external veto/gating. Multiple boards can be synchronized to build up complex systems.
In the case of DPP mode, data can be saved in time-stamped list mode to support higher input rates and improve the throughput performances. Piled-up events can be rejected or saved for offline analysis. The acquisition in DPP-PHA mode is fully controlled by the CoMPASS and MC2Analyzer software, which manage the algorithm parameters, build the plots and saves the relevant energy and time spectra. In the case of waveform recording mode, the user can take advantage of the CAENScope and WaveDump software to access and save the waveforms. For DPP-DAW mode, a c demo fully controls the acquisition, data plotting and saving.
Libraries and demo software in C and LabView are available for integration and customization of specific acquisition systems.
The DT5724 comes in a Desktop form factor with 2 or 4 input channels. The communication to and from the board is provided through USB and Optical Link interfaces.
