<p class="MsoNormal"><span style="color:#1F497D">The vendor is still being asked to make the port window to the drawing specification (16 uinch). Based on FNAL’s input, I revised the traveler (which is for JLab use only and is not provided to the vendor) to
allow for 32 as a surface finish. This is still a more polished finish than the FNAL requirement of 64, but will allow us to evaluate port windows that might be questionable to verify if they are acceptable for use.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi Tiffany,<br>
<br>
I took a glance at the R2. A couple comments:<br>
<br>
1. Step 2 says 32 Polish not 64 uinch as mentioned in revision notes<br>
2. Not sure if "Polish" is an accurate unit/jargon that everyone understands. Suggest to use "uinch" or "microinches" instead. On some drawings, surface finish is specified in micrometers so "Polish" may not be clear.<br>
<br>
I'd suggest that we don't let vendor know of our internal hard limit on the surface finish, i.e. 64 uinch, so that they don't deliver windows with poor finish.<br>
<br>
Thanks,<br>

<p class="MsoNormal">Added Step 1 Note on acceptable deviations from the Port Window Drawing (F10040909) - these are normal deviations for a stock blank flange. Added Step 1 Images Comment field. Added Step 2 instructions on when an NCR is needed for surface
finish - based on input from Brian Hartsell (FNAL) and FNAL's Vacuum Window Safety Chapter requirement for surface finish of at least a 64 uinch. Added Step 3 instructions on dimensions requiring an NCR - since this manifold is removed from the cryomodule
prior to shipment to SLAC, only dimensions critical to vacuum safety will require an NCR.<o:p></o:p></p>
