<font face="Calibri">Tiffany explained the reason for using 32 in
Step 2. That sounds good to me. My only other comment is on the
"Polish" as being unclear</font><br>

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>
