1) Vented T2 and removed rubber seal blanking plate, vacuum level appeared to be at normal operating ranges prior to the indium seal developing a small leak.

2) Removed B1 dust cover, cover was stuck to B1 flange due to oil residue. Oil residue is believed to be from a vacuum pump being turned on in the disconnected section of M9B line. Residue was seen on the bottom half of the B1 to Q2 flange, it was cleaned off using a cotton glove and acetone attached to a 20ft pole. Attempting to clean with wipealls left lint behind.

3) Mushroom pad jig installed in place, shielding reconfigured and platform plates in place. Target flanges to be installed tomorrow.
