    keyword=Loop 3 (LH2) pressure

    When power tripped off, the LH2 fill valve was closed (as a default
    state when power off). Once beam came to the target, part of the gas went to the tank, caused the pressure to drop. Once the valve was openned as in the normal running situation, the loop pressure is stable again.
