[Pansophy] SNS PPU He outlet & con bellows inspection

[Katherine Wilson]

Anne, each cavity string has three beamline bellows, one return warm to cold bellows, and one supply warm to cold bellows.

Inspections should prioritize parts for the first string unless there is a reason to do otherwise.

Therefore, I would inspect the bellows I list above as the priority.  I do not know where the traveler for the beamline bellows is if it’s not in Pansophy.

Thanks,
Katherine

Hello Naeem & Naeem



I was just in Inventory – we do not have space in the CMM room to bring down all of what they have , so can only bring down a sampling



Please keep in mind the CMM/Tuning Room has a lot of parts right now - we will be bringing in all  8 the C75 cavities this week, plus we already have RI-008 ., and have 2 SNSPPU cavities  in the CMM Tuning Room



The bellows were not delivered in kits, they are individual boxes  – so could you please let me know how many of each part number is needed per string



Please indicate by PART NUMBER the QUANTITY per string – here are the part numbers again……….

Hi Anne,



As Gary stated, I see that the HOBCB traveler is in Pansophy. The inspections seem to be visual and do not involve the CMM. I also share Gary's concern about this vendor. If not all 7 kits, please try and get a few of them (at least one kit) on the shelf.



Thanks,

Naeem

Correct, HOBCB will be used on the cold mass assembly.

Hi Anne,



I think you and Gary are referring to different bellows. Your list below is cavity string bellows, and Gary is talking about the helium outlet bellows.



Gary, is that right?



Thanks,

Naeem

Hi Anne,

PPU management enforces kitting so if all procurement implemented kitting, ideally you would expect to see 7 kits of all things needed for assemblies. I know there are variations due to the fact that in the real world, not everything can be easily kitted due to the size for example. And some items may have spares that are not kitted.

The SNS PPU He outlet & con bellows (HOBCB) are kitted.  My SOW & traveler both have kit definition. So there are 7 kits of HOBCB. And, I bought a couple spare bellows.

As to how many parts/kits to inspect, for the HOBCB, please inspect them all. They are made by Hyspan who delivered poor quality hoses to a subcontractor of us.  Bellows takes time to repair/make, especially when the vendor is Hyspan.

Thanks,
Gary
