#--------------------------------------------------------------- # # 2015/07/08 Kei Moriya # # This file explains the data taken with radioactive sources # for the polarimeter. # #--------------------------------------------------------------- All source data taken with the DAQ originally go to /gluonfs1/gluex/Subsystems/TPOL/data/calib_[RUN NUMBER].0 on the gluon cluster. The files can then be copied to /volatile/halld/home/kmoriya/TPOL_data for storage. When running over these files, copying to the scratch disk (/u/scratch/[username]) is recommended since the disk readout speed is much slower on this volatile disk.
