The ion pumps and TMPs of the vacuum pumping unit installed between OMMT~OMC in this series of work were removed according to Plan A in the attached document.
As a result, the frame of the vacuum pumping unit is only used to hold the bellows between OMMT~OMC.
The legs of the vacuum pumping unit mounts that were on the base of the OMMT and OMC, which had been pointed out, have been repositioned from the base to the floor at the ground level.
