[Pansophy] Faraday Window Manifold

[Mike Dickey]

Hi Tiffany,

We will need to know which parts and where on the part to engrave the serial number.  I expect that items 1, 2, & 4 will be engraved.  Item 3 should have a manufacture supplied serial number.  The preferred method is to have the vendor do the engraving/etching.  Parts should be marked with a unique identifier, Part Number-Rev-SN.  Assigning just a serial number to the 3 parts of the assembly breaks this rule.  As an assembly, only the main part, item 1, should be serialized, F10040886-C-01.  If each part is engraved, F10045762-A-001, F10040909---01, F10046507---01.

For the travelers, acronyms will be required, generally based on the name of the part.  I'll wait for your decision on serializing the parts before moving on with acronyms.

Based on Brian's response below, I believe we need an incoming inspection traveler for the Faraday Window Manifolds (see attached drawing).  We currently have one in house (sent from Fermilab) and have ordered ~10 more to be made by a vendor.  I do not believe that these manifolds are currently serialized; however, in order to create a traveler to document inspecting them, I think we need to add serial numbers.

What's the process for creating serial numbers for these manifolds and getting them added to part(s)?  Since the final assembly has 3-4 parts that could be disassembled for cleaning, so do all of them need to be marked with the same serial number, or do they need separate serial numbers?

Hi Tiffany,

It appears we ordered these as complete assembled assemblies from Lesker in 2017.  No dimensional checks were done, and incoming QC consisted of a leak check and visual inspection.  After that they were routed to magnetic hygiene, then they were put in storage until used for beamline assembly.

The one dimension I might recommend confirming is the window thickness since that's a fairly critical one, and would be needed to comply with beam window safety standards here at Fermilab.  If you have similar beam window engineering note requirements at JLab, I could forward you the note written for this.

Hi Brian -

For the Faraday Window Manifold, what inspection(s) are done at FNAL on the Faraday Window Manifold - individual components and/or assembly - prior to string assembly?  For example dimensional, magnetic, or visual inspection.  I didn't see any inspection requirements in the vCM traveler nor the FWM drawing, other than the leak check.
