Introduction

This is a DAQ for 1st gen CAEN digitizer for V1725, V17255S, V1230 with PHA and PSD firmware.

It has scope (updated every half-sec), allow full control of the digitizer (except LVDS), and allow saving waveform.

It can be connected to InfluxDB v1.8 and Elog.

Undergoing

the following additional functions are planned and I am working on them

• 1-D and 2-D histogram
• Online Analyzer
• support V1740 DPP-QDC
• synchronization helper

Required / Development enviroment

Ubuntu 22.04

• CAENVMELib_v3.3

• CAENCOmm_v1.5.3

• CAENDigitizer_v2.17.1

• CAEN A3818 Driver

• qt6-base-dev

• libqt6charts6-dec

• libcurl4-openssl-dev

• elog

The CAEN Libraries need to download and install manually. The other libraries can be installed using the following command:

sudo apt install qt6-base-dev libqt6charts6-dev libcurl4-openssl-dev elog

The elog installed using apt is 3.1.3. If a higher version is needed. Please go to https://elog.psi.ch/elog/

The libcurl4 is need for pushing data to InfluxDB v1.8

The QCustomPlot (https://www.qcustomplot.com/index.php/introduction) source files are already included in the repository.

Compile

use qmake6 -project to generate the *.pro

in the *.pro, add

QT += core widgets charts printsupport

LIBS += -lCAENDigitizer -lcurl

then run qmake6 *.pro it will generate Makefile

then make

if you want to use GDB debugger, in the *.pro file add

QMAKE_CXXFLAGS += -g

exclude some files from the auto-gen *.pro

The following files must be excluded from the *.pro, as they are not related to the GUI

• DataGenerator.cpp
• DataReaderScript.cpp
• EventBuilder.cpp
• test.cpp
• test_indep.cpp

Those file can be compiled using

make -f Makefile_test
