M&M finished wrapping the entire bake enclosure with Al foil and taping the seams. Bottom air temp has reached a new high of 95C (20C less than top air temp). This morning they swapped CP4's GN2 regen heater with CP3's - if we can resurrect that system we may have a chance to bring the entire enclosure up to uniform temperature. I raised the set point of bake enclosure to 130C (from 115C). 

Turbo pump back end measures 55C with 35C cooling water.
