Beam Pipe Installation and Support FDR 3/30/2022 Cacace --> Here are my notes and as far as I'm concerned all of the charge questions were fully addressed, barring my few minor comments. Given the central beam pipe is unsupported for a long span in the strongback, is vibration a concern, especially during lifting? Consider using blocks or foam between the beam pipe and the strongback. Consider using the supports off the INTT to lift the beam pipe out of the strongback. How is the beam pipe handled when moved from one strongback to the other? Can the same strongback be used? Is force that the pre-extended bellows exerts on the central beam pipe a concern for the EB weld? Can the bellows clamp be installed around the other surrounding supports? The INTT grew in diameter slightly due to manufacturing constraints, so the stanchion may need to be lowered slightly. Consider not using the south support off the INTT as it needs to be removed for the beam pipe bakeout, INTT installation and MVTX installation. Can the INTT be un/installed from the north if needed for maintenance? Maybe some time can be saved by preparing for installation for the INTT on the north and the MVTX on the south? The temperature between the beam pipe jacket and the INTT support tube should be monitored and potentially use a blower for forced air convection. Are there any concerns about the MBD and sEPD regarding the beam pipe? --> Need to design protective dog-houses around pipe to protect and prevent contact when people are working at north and south ends --> In general, we should move ahead and get all these final parts fabricated so we can test fit all the supports Jim --> This should be a critical lift and treated as such in WP and CLEF docs Side Note and Thought from Frank --> East stairwell blocks use of AH to IR transfer cart. Jim thinks for TPC install we will have to not have East Stairwell....Adjust consrtuction schedule. 1. Brian Brenton Presentation **Should we prototype Brian's MVTX-interfacing strap one more time...then practice all this when the actual MVTX and installation mock-up is brought to BNL later this summer? Brian's final deflection analysis is without bake jacket weight. Bake jacket removed before MVTX installed. The "roller stands" shown for beam pipe instal...What do these look like? Catalogue item? **Need to choreograph how to safely lift and transfer the beam pipe from the NEG coating strong back to the installation strong back. Can we use the spider supports to do this lift (Dan ?)...would need to install the INTT support tube hexagon face plates to do this....look at this in CAD? **Choreopgraph how a person on the north and on the south will hand lift the pipe to remove strong back **Add IR crane limit to Brian's IR lift study to make sure we can lift the pipe and strong back in all positions **Look at using a PEEK pillow block at the very center of pipe in strong back to help support pipe and bake jacket better 2. Chris Runyan Presentation ** Bellows is extended to minimize buckling risk during bake-out, about .6" from nominal both ends, creates a total 200 lbf tensile force on the beam pipe. is this OK for the Be-Ali section? Should we look at this FEA to check? **Installation of the INTT-install bellows support shell looks tight with the local bellows supports. Can this split shell be installed? **Add images of integration study between INTT installation rig and the bellows support stanchion. Dan says the INTT install tool OD has grown slightly due to manufacturing issues. We should revisit this and adjust bellows stanchion to make sure no interference. **Dan asked/revisited whether INTT could be removed or installed from the north if maintenace needed. Yes...can be done using bellows clamp support for the north bellows....for future maintenance. We want to initially install all from the South to keep the north beam pipe supports intact the whole time. 3. Chris Runyan Bake Presentation ** TPC ID surface temp due to 41 deg C INTT tube radiating onto TPC...can we look at this black body radiation analysis? --> What is the requirement for TPC max allowable temp? Need to find out from TPC. Can Chris R attend next TPC meeting to present and ask question. ** Dan C --> Provide some temp monitoring inside INTT tube and between INTT and TPC. Dan W --> This is done for STAR plus some forced air cooling during break. sPHENIX could provide some blown air...?? Can we set up a bake controller and a max TPC temp to turn off bake? **Dan C --> Present integraiton with sEPD and MBD for completness 4. Sumanta and Dan Beam pipe bake jackets delivery delayed to July --> Check on this and stay on top to make sure not delayed more. Dan says this will not impact the NEG coating operation at BNL... CA-D vacumm is going to use NEG pit for EIC amorphous carbon R&D before sPHENIX pipe NEG coating. Need to understand this schedule... With delayed sPHENIX schedule they think this can all work out because sPHENIX pipe work is not as urgent... Will be stored and delivered to sPHENIX with Krypton or other gas inside. Will have to vent to sir during install, should install ASAP after that. 6/15 --> Pipe from Materion 7/1 --> Bake Jacket from BriskHeat --> Start NEG coating for three weeks of Al-Be pipe 9/30 --> all other conventional pipe available and NEG coated All pipe available by early October. Questions and concern about lacing and ability to remove jackets. Walter asked about adding a leash that starts in middle at IR and extends out opposite side of jacket half so we can pull laces from either direction. Jim --> Can INTT support weight of bake jacket if it falls off beam pipe? Dan says INTT supports structure would be fine. ** Work this chorepgroahy out --> remove spiders at each side to take bake blanket out locally. **Provide a better view of the actual TPC south end crowding to get a better idea for handling the bake blanket. What does that are areally look like during this operation? **BNL will do a thorough receipt inspection (dimensional and vacuum pump) when received from Materion. We also need to provide as built straightness and other OD dimensional checks for MVTX fit up. **Should we build a dimensional inspection jig? ESH Notes - extensive work planning will be needed, including critical lift evaluation and work plan, and considerations for beryllium contamination testing. The beam pipe should have a wipe sample performed on arrival to confirm there is no surface contamination. The C-AD ESH group needs to be involved early.
