Moved cables that touched neg pumps. See 
photos. Please bear in mind perspective.
Note avoiding touching chamber 
bottom is not possible.

Re-installed motor to fix alignment 
issues. All good. See attached.

Started pumping down. Reached 3E-1 mbar in 
20 minutes (ok). Turbo on. After one hour 
turbo stable at 0.85 A, pressure on Pirani 
at 1.1E-2 (not reliable). 

IE514 doesn't report pressure, i.e. > 1E-4 
mbar.

Leak likely. Will try to pinpoint 
tomorrow. We only changed 10 flangese.
