slccom:restore_bic_luminosity_data.com


Command file used to restore luminosity to values stored in a history file. The arguments to this command file are
 

ref_standalone:restore_luminosity.c


Currently, a 24-hour history, once per minute, of luminosity data is saved to disk on MCC. This function allows the user to specify the data for which minute, within the previous 24-hours should be restored to the luminosity PVs. The restore luminosity function is executed from DCL using the command file restore_bic_luminosity.com (see below).
 

ref_magshr:save_lumi.c


This module has two function, the pupose of each is described below. This function is called from the VMS standalone program inject_eff().
 

save_lumi()
The purpose of this function is to save luminosity data to disk on MCC. To view a list of the EPICS lumionisty PVs saved click here. The data is saved at the rate of once per minute from from the injection efficiency standalone.  The filenaming convension used is L_<minute_of_day>.DAT  and the file data format used is binary.  The directory location where the data is saved is BIC_LUM_DATA, which can be seen from MCC and MCCDEV. The files are purged so that only the most current version is kept.

restore_lumi()
The purpose of this function is to restore luminosity data. To view a list of the EPICS luminosity PVs restrore click here. This function needs to synchronize with the sequencer program on the BIC ioc which updates the luminosity.

SCP Displays


Director's Disply - This provides history plots for luminosity data, which can ba compared with the medm_CUD_lum.adl display and the bic_shift.dl display.  This panel can be reached off of the main PEPII Index Panel.
