CAEN digitizer
Model
| Model | Energy resolution | Sampling rate |
|---|---|---|
| V1725 | 14-bit | 250MS/s |
| V1730 | 14-bit | 500MS/s |
| V1740 | 12-bit | 62.5 MS/s |
DPP firmware
Both V1725 and V1730 can be equipped with the PHA (pulse-height analysis) or PSD (pulse-shape decimation) firmware.
From the programming point of view, the board registers are very different for the two firmware.
required library
On Linux (Ubuntu 18.04+), two CAEN libraries are required to run the digitizers.
- CAENVMELib
- CAENComm
that would be enough for running the CAEN CoMPASS.
For custom programs, an additional library is needed
- CAENDigitizer
FSU DAQ
https://fsunuc.physics.fsu.edu/git/rtang/FSUDAQ
The FSU DAQ is based on BoxScore. The core is the digitizer class that directly controls and reads out the CAEN digitizer. The GUI of the DAQ uses CERN ROOT GUI elements.
The Goals for the DAQ are:
- support V1725, V1730, V1740 digitizers
- multi-thread readout and real-time time sorting (possibly events building)
- extendable to other digitizers and functionalities
- user-friendly (full GUI, limited terminal output)
- easy to maintain (avoid abstract coding and entirely objective programming)
- for Ubuntu 22.04 or equivalent
- binary output or root tree output
The Digitizer Classes
The Digitizer classes are based on the DigitizerClass.h/C. The derivative classes are DigitizerPHA.h/C and DigitizerPSD.h/C. The digitizer classes stores only the connection and board information. It provides an interface to better control the digitizer, for example, manipulate the bits for the control bit.
