While preparing to set up the testing of the new Hall C HV modules, I noticed that some of the pins on the A7030TN socket did not extend as far as others, I have documented the issue in a short word file. It is attached to this email.</div>

As far as the testing is concerned, I have discussed the matter with DSG management and we have developed a plan to move forward with the module testing.

<ol>
<li>We have obtained an HV breakout chassis, which was initially built to service two A7030L, 24 channel modules. DSG will modify this chassis (extract pins from the Radiall connectors and re-pin) to work with the Hall C A7030TN 36 channel module. DSG will
then move forward with channel by channel testing of the Hall C modules.<br>
</li><li>Hall C will still need a distribution box design for installation in the end station. I have developed a parts list to fabricate a chassis with an attached cable, similar to the CAEN product.
</li><ol style="list-style:outside none lower-alpha">
<li>We can improve on the CAEN design by utilizing a custom shielded HV multi-conductor cable from General Wire Products. The length of this cable can be made so that the distribution is much closer to the detector, instead of running long individual HV coax.
<br>
</li><ol style="list-style:outside none lower-alpha">
<li>If the length is known, please forward that length and I can work it into the parts list.</li><li> The minimum length for a 40 conductor shielded, cable is 1000' @ $6.28per/ft. </li></ol>
<li>A quick cost estimate for the parts including a spool of 1000' of the cable is $1700 to $1800 per distribution box, making 17 boxes with 50' multi-conductor cables.
<br>
</li><ol style="list-style:outside none lower-alpha">
<li>Adjustments to this estimate must be made if more than 17 boxes are needed or the runs are longer than 50'.<br>
</li></ol>
</ol>
<li>Hall C will still need a testing chassis, the chassis DSG will modify for use, will eventually have to be converted back to a dual 24 channel chassis.
<br>
</li><ol style="list-style:outside none lower-alpha">
<li>DSG can fabricate this chassis using HV hook-up wire and the same components specified for the Hall use application. We have most of the components on hand, except the chassis box and the spool of HV hook-up wire.<span style="color:rgb(222,106,25)"> Hall
C will need to purchase the components to replenish what we have on hand and buy the chassis and wire spool. The total cost is approximately $2400.</span> I estimate 5 to 6 weeks to complete the fabrication, due to chassis and hook-up wire lead time.
<br>
</li><li>Alternatively, CAEN sells a chassis for ~$1900, however the lead time is 12 weeks.
<br>
</li></ol>
</ol>
<div>Please review this information and let us know on the options you would like me to start the procurement process concerning points 2 and 3, as well as your thoughts concerning the module connector pins issue.
