    keyword=Reduced Loop 3 coolant flow, increased HP limit.

    Tim called me that loop 3 temperature dropped below 20 K.
    It was due to too much coolant. Tim was not able to close it down.
    I did it from my office, reduced flow from 10.9g/s to 10.1 g/s.
    And also increased HP heater limit from 100 Watt to 150 watts.
    Tuned off beam compensation.
    The target is stable now.
