- Reconfigure the LFB (if changing total gap voltage)
- Reconfigure the Low Group Delay Woofer (if changing total gap voltage)
- Change Comb Filter Settings (if changing total gap voltage) and Enter Station Gap Voltages (by hand or with loading EPICSconfigs)
- May need to change the woofer setup
- May need to change the Power Balance Feedback Setup
- Check collision phase for luminosity
- May need to alter the bucket pattern to keep charge/bucket similar for luminosity
SUMMARY OF SETTINGS for HER RF stations:
A table of optimized configurations is no longer maintained given the dynamic nature of the RF setup. Rather, "snapshots" of the RF setup can be taken from the SCP with "PEP_RF_SNAPSHOT.edl" from PEP-II Tune Panel àEPICS -> EPICS Display Panel à -> PEP RF Setup. These snapshots of relevant parameters are then regularly saved to the MCC elog E-log for reference.
1. RECONFIGURE THE LFB (if changing the total gap voltage)
MANUAL OPTION:
- To load the proper configconfiguration, go to the SAVE/RESTORE panel for the HER/LER EPICS LFB.
- Either select Gold setup 0, Gold setup 1, or User defined. If using a user defined file name, enter it in the file name line (you must hit RETURN while the mouse is in the filename field, or else the filename will not be loaded).
- Hit "Restore" and exit this panel.
- Next, go to "PEP-II HER LFB Control" panel and hit "Stop" and "Run" to restart the LFB with the new settings.
Note: You can access the LFB configuration directory from any UNIX AFS (flora) machine. Just change directory to /nfs/mccfs0/u1/lfb/lfb/tbl/
2 . RECONFIGURE THE LOW GROUP DELAY WOOFER (LGDW) (if changing the total gap voltage)
...
(You should not need to STOP and RUN the LFB to pick up LGDW changes?)
Note: You can access the LGDW configuration directory from any UNIX AFS (flora) machine. Just change directory to /nfs/mccfs0/u1/lfb/lgdw/dl/sr/HER/ or .../LER/
3. COMB FILTER SETTING (if changing the total gap voltage) and STATION GAP VOLTAGES.
