ET sytstem How To


To start up ET_system, logon to clon00 (clon10 is DAQ machine for current ongoing experiment. Don't use clon10) with primex account. Unless you know what your are doing, please work in /home/primex/offline. Open up 5 xterminals(xtem1, xterm2, xterm3, xterm4, xterm5).
  • xterm1: start_primex_et
  • xterm2: et_monitor -f /tmp/et_sys_primex -p 2
  • xterm3: file2et /scratch/primex/datafile.dat
    (e.g. /scratch/primex/primex01534.dat.00)
  • xterm4: program -online ET:primex
    (e.t. tac_calib -online ET:primex
Now it is ready to access histograms via ET system. In term5, lounch root (make sure you have roottools.C file in the working directory.) To Draw histograms, see README roottools.C .
In the case transfer data from clon10 ET system to clon00 system, Need following extra step:
  • clon10> start_primex_et
  • clon00> start_primex_et
  • clon10> et2et ET:primex
