Willy Andersson | Quench Recovery | Powerleads warming up again. | Got a page from Don Flemming at about 18:50
wondering why the power
lead temperatures were rising. See attachment |

Doug Preddy | Normal Running | power leads | Power cycled HIC 142 with solenoid power at
400 amps. Flows > 240mm and
temps have dropped. |

Doug Preddy | Normal Running | power leads going unstable | power lead ripples increased over last couple
of days. They are quickly
dieing out now and the temps are startint |

Doug Preddy | Normal Running | power leads again | Same story as yesterday. Ripples dieing out,
flows down to <200 mm, temps
increasing. Turned HIC 142 down to 0.4 then |

Doug Preddy | Quench Recovery | Power leads flow | Throttled back the LHe in until the power
leads started to warm. My goal is
to flow "warm" gas (hopefully 80K) through |
