[Dsg-hallc_nps] HV rating of NPS Samtec connectors

[Peter Bonneau]

Hello,

DSG is glad to be working on the NPS project.



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.



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 of the system, in particular,  how the voltage connections are made from the patch panel to the PMTs, e.g. what kind of cables are used inside to make the connections.



We’ve started searching for an alternative connector rated for the detectors operating voltage. If needed, DSG can design new boards or cable assembles or both.


 DSG is will do whatever is necessary to ensure the success of the NPS detector.
