    We found a bad vacuum on right Q2 cold return. This U tube was looked at between experiments and was good so we want to take a closer look at it when we have time. We left the pump on it.

    Installed, purged and have opened (cracked) a bayonet cooldown bypass on the right Q2 in an attempt to lessen the heat bumps that occur when a fill valve opens after a long closure.

    Cryo noted a correlation between our magnet trips and the operation of the target JT valve. They are looking at limiting the control loops on the target controls.
