This is the DAQ software and EPICS IOC for the CAEN digitizers which are connected the the helium-3 tubes in BEAST. These packages will need to be installed: kernel-headers kernel-devel gcc.x86_64 gcc-c++.x86_64 libX11-devel.x86_64 libXpm-devel libXft-devel libXext-devel python redhat-lsb-core The EPICS base will need to be installed as well (located at https://www.aps.anl.gov/epics/download/base/baseR3.14.12.3.tar.gz) you will need to set EPICS_HOST_ARCH to the output of EpicsHostArch.pl using this command: export EPICS_HOST_ARCH=$(perl startup/EpicsHostArch) Now you can make using make clean uninstall make When installing, you may get an error about 'readline.h'. if this occurs, open 'configure/os/CONFIG_SITE.Common.linux-x86_64' and comment out the line that says 'COMMANDLINE_LIBRARY = READLINE' (line 27ish). Now install the CAEN libraries (located in caen/) in this order: CAEN VME library (CAENVMELib-2.30.2.tgz) CAEN USB library (CAENUSBdrvB-1.3.tgz) CAEN Comm library (CAENComm-1.02.tgz) CAEN digitizer (CAENDigitizer_2.3.2.tgz) instructions are in the tarballs. Now install ROOT (use V5.34.34, located at https://root.cern.ch/download/root_v5.34.34.source.tar.gz) instructions are in the tarball make sure you source the initialization script: source bin/thisroot.sh (from the ROOT base directory) Once these installations are complete, the he3DAQ software can be built. First, open 'configure/RELEASE' (from the DAQ base directory), then change 'EPICS_BASE' to point to 'base-3.14.12.3/bin', wherever that location is. now build the he3DAQ software: make clean make Assuming the build is successful, the IOC can be now be run: ./st.cmd
