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.
