ITMX Manifold Cryo Pump Baffle Installation
Scott S, Nicole W, Gerardo M, Randy (Apollo, Mitchell R

Yesterday the ITMX MCPB was installed just before lunch. This baffle was slightly larger in diameter than previous assemblies causing a difficult install. The larger diameter necessitated a modification to the lower copper plate D1100821 which is part of the eddy current damper. The range of adjustment allowable by the slots was insufficient for proper spacing on the eddy current damper. The work around is to lengthen the slot. The two lower copper plates needed for this baffle will be modified clean and installed once the parts are available. The remaining parts will be modified and re-classed. The lack of sufficient travel on lower copper plate was also an issue for both ITM's at LLO although modification was not needed.
