Just do it.
Spreadsheet from Dan VanWinkle on how to keep 16 MV when we lose one RF
station. (May 2007). All values are in KV.

Cav V/Cav 1200 600EPICS CONFIG LOAD:
SCP config files for use in the parking of a given HER RF station exist. The configuration region is called HER_GAPV (SCP path INDEX -> CONFIG -> MISC CONFIG -> EPICS CONFIG -> HER GAP VOLT) and the NORMAL directory has setups for parking each station. Configs for 2007 are still in the works These new configuration files save the following parameters for each RF station in HER:
- Desired gap voltage
- LFB woofer link state (ON/OFF); meaning woofer is turned on or off. This does not load LFB configurations, it just tell tells the given RF station to woof or not.
...
- Check for no circulating beam in the machine.
- Get Gap Voltage total from EPICS.
- Calculate new comb filter coefficient and enter it into the inactive bank on the Comb-2 modules.
- Activate Activate the inactive bank.
Note 1: To back out of the changes made by this program; just make the new inactive bank active. (For all Comb-2 modules)
Note 2: There is no need to save combComb-2 configuration files since the Matlab function can be run anytime one needs new comb filter coefficients.
