    keyword=Left Arm Q1 Trip

    At 16:15, left arm Q1 tripped due to low He level. When trying to reset it (following
    the reset procedure) it tripped again. Called Scott Spiegel and he claimed that the
    trip was real and was caused by high current (2659 A) causing He to boil off.
    He requested to increase He cool power (from 66% level to 70%). We managed
    to reset Q1. We lost about one hour of data taking.
