The following work was performed on May 27 & 28, 2015:

- The beam dump 10kW Remote Handling setup was arranged as shown in the attached procedure

- The EHDT split ring clamp was found to be installed too far downstream and the pole tool could not be installed properly;  the position was adjusted

- The cuff of the previously installed used seal was found to be damaged because it was not located properly on the EHDT side flange at the bottom when the clamp was closed.  Thorough inspection (visual from top, camera for bottom) must be used in the future to prevent this from happening again

- Flange gap was measured with the beam dump in far upstream and downstream positions:  .190" and .762" 

- Seal width is 0.255", and cuff width is 0.475", giving 0.297" clearance for installation, and .065" bellows compression when closed 

- EHDT beam pipe was adjusted approximately 0.125" downstream to give more bellows compression with seal installed and the BD advanced upstream 

- New flange gaps: 0.083" and 0.649;  New instillation clearance: 0.174"; New bellows compression: 0.172" 

- Two trial seal installations were performed according to the attached procedure (no major issues encountered)

- A new helicoflex seal was used for the final installation (also according to the procedure).  One of the clamp jaws did not seat properly around the flanges at beginning of travel; this was overcome by backing up 1/4 turn and adjusting the clamp angle to get the jaws seated properly.  After this the clamp closed normally.

- A helium leak check was performed by Anothony Ip from Vacuum Group:  No leaks found!
