Description

I3 attempts to block settings to the anode program that exceed a calculated "Max HV" in MeV/Turn. This "Max HV" is calculated in [hv.cpp > rinit()] as:

rfmax = hvp.par.tubmax * hvp.par.tubgain * cs->pars[PAR_RFNUM] / 1000.

Where pars[PAR_RFNUM] is the number of RF stations active
and hvp.par.tubmax is the maximum tub voltage (kv) found in appdb.wu.i3_parameters
and hvp.par.tubgain is average RF cavity tube gain found in appdb.wu.i3_parameters

However, the operators have reported seeing the warning that occurs when reaching the "Max HV" threshold and stil occassionally being able to set the values higher.

I suspect what is happening may be related to the number of stations declared in I3. When this was first reported to me there were a couple MI stations left off and then turned on that day. Unfortunately, I have virtually no way of telling if any of the other parameters were edited because of issue: 8297.
