If the cryo flow is limited when Qweak needs to use most of the ESR flow for high current running, we can put one loop in minimum cryo consumption while keep the running loop normal. Then when switch to use the other loop, the Target Operator should follow the following steps for switch from loop 1 (LD2) to loop 2 (LH2): 1) With beam not on cryotargte, lower cryo flow on loop 1 (reduce J-T, 1% per minute) until high-power heater power is near zero. Reduce fan speed of loop 1 from 20% (60Hz)to 10% (24 HZ). 2) Then increase the cryo flow to loop 2 to have high-power heater power to be 50+beampower (10uA = 55 watts). And change the fan speed to 60 Hz (25%). For switching from Loop 2 to Loop 1, just need to reverse the order.
