- Abstract:
- For the Advanced LIGO Project, the mid-station BSC chambers at LHO were moved to the end-stations. Since there are no longer any chambers and interferometer elements in the LHO mid-stations, it is reasonable to consider decommissioning the mid-station cryopumps. There are 2 pumps in each mid-station at LHO. This would reduce the cost of LN2 consumption. However there are a number of risks which must be addressed and a work plan is needed.
The purpose of this memo is to submit a definitive proposal to the Vacuum Review Board (VRB) for consideration, prior to pursuing an Engineering Change Request (ECR).
