Data Acquisition System
The NSCL Data Acquisition system is a general-purpose nuclear physics data acquisition system in use at the National Superconducting Cyclotron Laboratory at Michigan State University.
NSCL Data Acquisition Documentation http://docs.nscl.msu.edu/daq/newsite/index.php http://docs.nscl.msu.edu/daq/newsite/ddas-1.1/pages.html
1) Turn on the crate.
2) Open a terminal on SPDAQ01. sudo /usr/opt/plx/Bin/Plx_load 9054. Enter password.
3) cd readout/crate_1 $DDAS_BIN/nscope
4) File→save. save a set file. Enter the name of that set file in the cfgPixie16.txt. 1 # crate id 1 # number of cards 2 # slot of first card /path/to/my/params.set # path to params
5) $DAQBIN/DDASReadout begin/end/exit
6) Open a second terminal. cd readout/crate_1 $DAQBIN/dumper –count=50 when running Readout.
you'll see
