    keyword=Hall A target cooldown completed

    Hall A target cool-down completed. I added some D2 gas at the end.
    The conditions are:
    Loop 1: LD2 at 22K, 25 psi, fan at 24 Hz. HP heater power ~ 50 watts.
    Loop 2: LH2 at 19K, 25 psi. fan at 46 Hz. HP heater power ~100 watts.
    Coolant flow at 14.2 g/s, 15K supply at 15.3 K, return at 24.8 K.
    They may change some for the next a few hours before stabilize.
    TO can adjust J-T accordingly to have reasonable HP heater power on both loops.
