========================================================================== Date: Tue, 28 Aug 2001 16:04:05 -0400 From: Johann M. Heuser To: phenix-dch-l@bnl.gov Subject: RE-ARRANGED DC HV TOOLS Dear colleagues, this is to provide information on re-arranged paths, how to start programs and where to find relevant configuration files. cheers, Johann ========================================================================== ===================== The HV paths are now: ===================== /home/phoncs/heuser/hvcontrol/hvmonitor /set_dc_parameters /logger /standby_restore /tools -------------------------------------------------------------------------- -------------------------------------------------------------------------- hvmonitor: displays the current status of the Drift Chambers ========== path: /home/phoncs/heuser/hvcontrol/hvmonitor make: a) setupepics b) make -f hvmonitor_dc_Makefile (re)start: display on PHONCS5 and PHONCSXT0 screens: /home/phoncs/heuser/hvcontrol/hvmonitor/restart_dc_hv_display it is also possible to use the command: /home/phoncs/bin/restart_dc_hv_display config file: hvmonitor_dc.conf masked channels: hvmonitor_dc.masked_channels -------------------------------------------------------------------------- -------------------------------------------------------------------------- set_dc_parameters: Allows to change automatically a variety of parameters, ================== e.g. ramp-up speed. Saves ** A LOT ** of typing. path: /home/phoncs/heuser/hvcontrol/set_dc_parameters make: a) add the token-passing-library to the path setenv LD_LIBRARY_PATH /export/software/oncs/hv/:$LD_LIBRARY_PATH b) setupepics c) set_dc_parameters.make run: /home/phoncs/heuser/hvcontrol/set_dc_parameters.run config file: set_dc_parameters.config -------------------------------------------------------------------------- -------------------------------------------------------------------------- hv data logger for DC: program to archive the HV settings into text files. ====================== path: /home/phoncs/heuser/hvcontrol/logger make: a) setupepics b) make.csh (re)start: /home/phoncs/heuser/hvcontrol/logger/restart_dc_hv_logger show the current process: /home/phoncs/heuser/hvcontrol/logger/show_logger the logger stores the date files in: /home/phoncs/heuser/hvcontrol/logger/hv_data/dc for every time stamp, there are 4 files for every property: e.g. dc_w_s_20010928170826.MVI dc_w_n_20010928170826.MVI dc_e_s_20010928170826.MVI dc_e_n_20010928170826.MVI the properties are: MVI - measured voltage DVI - demand voltage MCI - measured current STI - status -------------------------------------------------------------------------- -------------------------------------------------------------------------- check of the active channel configuration: tool for MEDM GUI. ========================================== cathodes: /home/phoncs/heuser/hvcontrol/tools/check_config_c.csh pgb: /home/phoncs/heuser/hvcontrol/tools/check_config_pgb.csh bulks: /home/phoncs/heuser/hvcontrol/tools/check_config_bs.csh -------------------------------------------------------------------------- -------------------------------------------------------------------------- standby-restore: tool to ramp the Drift Chambers to standby ================ voltages and ramp back to operational voltages. 1) standby: at the end of the last data taking run, prior to beam dump, =========== start the script: /home/phoncs/heuser/hvcontrol/standby_restore/dc_standby.csh The Drift Chamber subsystems which are enabled in the configuration file are ramped down to the standby voltages that are also defined in the configuration file. All Drift Chamber subsystems are operated simultaneously. 2) restore: when beam is commissioned, shortly before the data taking starts, =========== start the script /home/phoncs/heuser/hvcontrol/standby_restore/dc_restore.csh The Drift Chamber subsystems which are enabled in the configuration file are ramped back to the operation voltages as of prior to the standby command. configuration file: contains the standby voltages and the enable ===================== status of the Drift Chamber W_S, W_N, E_S, E_N. /home/phoncs/heuser/hvcontrol/standby_restore/standby_restore.config channel description files: ========================== the following files are to be used: a) DC_EAST: standard description files that are also used for the MEDM gui: /export/software/oncs/epics/R3.13.0.beta11/epicsB/app/hvca/db/dc_e_s.dat /export/software/oncs/epics/R3.13.0.beta11/epicsB/app/hvca/db/dc_e_n.dat b) DC_WEST: the description files for DC_WEST are modified versions, with the extra channels listed in different positions immediately after the bulk supplies of the relevant groups of keystones. If one changes the original dc_w_s.dat and dc_w_n.dat, one has to reflect those changes in the modified files. /export/software/oncs/epics/R3.13.0.beta11/epicsB/app/hvca/db/ dc_w_s_standbyrestore.dat /export/software/oncs/epics/R3.13.0.beta11/epicsB/app/hvca/db/ dc_w_n_standbyrestore.dat -------------------------------------------------------------------------- --------------------------------------------------------------------------
