<p>Hi Jim,</p>
<p>I believe so, since we have been talking about doing that all
along (carbon infused nylon or something like that), but the best
person to comment on that is probably Wouter.</p>
<p>Cheers,<br>

<p>Hi Jim,<o:p></o:p></p>
<p>Yes, for next prototype we want it to be black and printed
from radiation hard material.
<o:p></o:p></p>
<p>This was printed with the material that was being used here
already and should be considered a first assembly test. For
that purpose this was ideal, since we were able to identify
some issues<br>
with the design that we need to address. Thanks to Wouter
pushing the purchase of so much new equipment here, through
the faculty no less, we should be in a position to turn out
the next prototypes pretty rapidly, over the summer,<br>
until we have something that works really well. It is very
useful, even if we end up deciding to have it machined from
aluminum in the end.

<b>Subject: </b>[EXTERNAL] Ring 5 prototype</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
Nafis and I put together the first full scale Ring 5
prototype this <br>
afternoon (see attached figures). The entire mounting
structure is 3D <br>
printed and the quartz and light guide are installed, and
we test fitted <br>
the PMT.<br>
The structural integrity is very good, even though we did
not use a <br>
particularly special (say carbon fiber infused) material.
We will be <br>
improving several things we noticed, which made the
assembly cumbersome<br>
and which would eventually improve the light tightening.<br>
<br>
Regards,<br>
<br>
Michael<br>
