the clearance on the PCB HV is about 2.2mm between two pins.<br>

</div>
<div style="overflow-wrap: break-word;">Peter:
<div><br>
</div>
<div>A number of us are concerned about voltage ratings of the connectors and cables. I plan to talk to Chris Cuevas about this to see if there is a path forward by doing the right kind of testing. Our voltages are certainly above 600 V, which seems
to be the voltage rating for the SAMTEC connectors. On the other hand, our currents are very low.</div>
<div><br>
</div>
<div>I am trying to understand the full path of HV from tube to the CAEN supplies. Here is what I understand. (I may have some confusion between IPD and PMSD. I think IPD are the connectors, and manufacturer supplied cable assemblies, but I am not
sure.)
<div><br>
</div>
<div>
<div>1. Each PMT has a receptacle for a SAMTEC IPD1-05-S-K connector.</div>
<div>This will deliver the HV and take out the signal.</div>
<div><br>
</div>
<div>2. For each PMT we will have a cable assembly with a SAMTEC</div>
<div>IPD1-05-S-K connector on the PMT end, this breaksout into two cables,</div>
<div>one for signal and the other for HV. The signal is an SMA connector</div>
<div>and the HV is a Fisher "S 102 A 018" connector. These cables are</div>
<div>being fabricated by the DSG.</div>
<div><br>
</div>
<div>3. Each set of PMT (a column) cables plug into a board with Fisher</div>
<div>receptacles for the HV.</div>
<div><br>
</div>
<div>4. This card routes the HV to a set of PMSD receptacles. (Two for</div>
<div>SAMTEC PMSD-15-206-K-D-LUS and one for PMSD-08-206-K-D-LUS.)</div>
<div><br>
</div>
<div>4. Ribbon cables with these PMSD connectors on each side route the HV</div>
<div>to a board on the top of the detector frame.</div>
<div><br>
</div>
<div>5. Long cables connect from the top of the detector frame to the HV</div>
<div>supplies. Each cable has 36 channels. On the power supply end is a</div>
<div>Radiall connector (recently ordered by Aaron). On the detector side</div>
<div>are two SAMTEC IPBD-15-D-K and one SAMTEC IPBD-08-D-K.</div>

While working on the procurement of NPS components, we noticed that the HV rating of the Samtec connectors is only 850V. Since the detector will operate at ~1100V, we have serious concerns about the safety and performance of the connectors. </div>

We’ve seen some very detailed CAD renderings of the assembled detector. Are there assembly drawings and manufacturer parts lists available for all the individual cable & board assemblies for the detector? We would like to see these for a deeper understanding
