[Pansophy] New DocuShare document routing task (Step 1 Completion): PLACLN-VTA-CAV-VTRF-R1.docx

[Tiffany Ganey]

Comments have been incorporated and step have been renumbered.  I also deleted references pertaining to the HOM survey from the cover sheet.  See highlighted text below in this email chain for changes made to the procedure.  The updated procedure PLACLN-VTA-CAV-VTRF has been added to the Ready for Approvals folder.  Please delete the current / disapproved version, move the updated procedure to the Approvals folder, and send the updated procedure version out for approval.

Tiffany,

As with the previous disapproved procedure, please make the necessary changes, then reupload to ready for approvals. Thank you.

You have a new DocuShare document routing task:

Step 10 We do not really care about the other passband modes.

Step deleted


step 11 We do not need a cold HOM scan.

Step deleted


Step 12.  HOM couplers do not have a  QL.  They do have Qx where that is the Q of the port.


1/QL = 1/Qo 1/Q1 + 1/Q2 +. . . + 1/QN

Step deleted


step 13 We do not care if the cavity frequency is high or low when we are plasma processing.

Step deleted


step 14 we no longer save the scope trace.

Step deleted


Step 17 we do not have an administrative limit.
Removed reference to “admin limit” in initial FE Onset and initial Rmax.
Initial FEonset: onset of field emission (FE onset, defined to be the first measured gradient where measured radiation is >= 1e-2 mR/hr). If no field emission is detected, insert a value of 50 MV/m.
Initial Rmax value for the highest radiation level inside Dewar lid. If Rmax is background, insert 1e-3 mR/m for this parameter.


Step 19 No NCR if the cavity does not meet spec.  As a matter of fact no NCRs for this work.
Removed NCR requirement for both step 19 (initial) and step 21 (post processing)
At 2.07K, was cavity RF processed (conform specifications in 1497 MHz VTA RF Testing Procedure<https://jlabdoc.jlab.org/docushare/dsweb/Get/Document-48113/CP-C100-CAV-VTRF-R2.docx>) to achieve performances over 25 MV/m? Record pertinent information at the right.


Step 22 No NCR and not really required.
Step deleted


Step 23 we are not doing a Qo vs T data set.  That adds 2 or 3 hours to the test.
Step deleted


Step 28 Q vs E and Rad vs E are now on one plot also delete Qo vs T plots

Updated required file uploads:
Upload processed Qo and Rad-vs-Eacc graph (in PDF format) using file name: CavID_ QoAndRadvsEacc.pdf.
Upload processed HOMa and HOMb vs Eacc graph (in PDF format) using file name: CavID_HOMaHOMbvsEacc.pdf
Upload processed f-vs-Eacc2 graph (in PDF format) using file name: CavID_FreqvsEacc2.pdf.
[[QoAndRadvsEacc]] <<FILEUPLOAD>>
[[HOMaAndHOMbvsEacc]] <<FILEUPLOAD>>
[[fvsEacc2]] <<FILEUPLOAD>>



Step 30 no HOM survey required.
Step deleted


Step 31 No NCRs required for this work as it is not really production.
Step deleted


Will be approved after comments addressed.
