<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.

<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>
