Tues July 26th had some problems with the transfer chamber

Transfer chamber was not going below -20in pressure, when usually it will drop all the way to -30in

To by pass and put the uranium target into the glove box, the transfer chamber was flushed 10x - when opened, no change in H2O and O2 in glove box; therefore, 'bypass' worked.

Pump removed and tested by vacuum group - showed no reading on gauge when being tested, how was it even pumping?

New pump installed July 27th.

New pump = bigger/ faster/ quieter
