keyword=fpp turning on and gas flow
We (RG, Mark Jones, Gerfried Kumbartzki, Jack Segal)
turn the FPP HV back on and look at the gas flows.
- All HVs okay except chamber 1, channel 7.7.5, draws high current.
Mark locates the problem module. The problem wire still needs to
- chamber 3, channel 7.8.5, trips. This is a 3x section.
- We tweak the flows up for chambers 1 and 3x, but down for 2.
Chambers 3uv and 4 are left alone.
- Jack determines that the gas system is currently running on
for ~ 5 minutes, off for ~1 minute, for ~84% duty cycle. He
suggests not increasing the gas flow total above current levels.
(Also, the right arm VDCS draw such small amount of gas turning
them off will make only a very small difference.)
