keyword=Loop2 (H2) fan and j-T valve adjustedWe are doing moller measurement on day shift, Checked with RC and found out the tasrget will be LD2 after the moller. The heater power for Loop2 is as high as 190 watt. I lower the Loop2 (H2) fan frequency to 31 Hz (13%) and turned its J-T valve to 23% such that the heater power stays at arround 75 watt. Note that one should change it back if LH2 target is used.
