Hi Youri,

It isn't clear to me exactly what you need fabricated.

Regarding the LEMO REDEL connectors, for the SVT we bought those pre-assembled from WIENER with flying leads on the other end and as such have no tooling available to work on these connectors.

I can get you the part number if you'd like to order the same ones as was used for SVT, maybe they can get ordered with a different length?

If you want to make completely new cable assemblies you might want to see if Fast Electronics has the tooling necessary.

Brian

Dear Amrit,

      Currently High threshold Cerenkov Counter (HTCC) in Hall B is using CAEN HV power supply. This source is too noisy and therefore filters were required. Besides PMTs used in HTCC sometime unexpectedly significantly change gains. It is totally unacceptable since HTCC is part of CLAS12 trigger. So our experience with CAEN forces us to replace it with WIENER power supply. We have WIENER crate, HV modules, HV distribution box. We also have multiwire HV cables but no connectors.
      Please, I would like to ask DSG build for us three cables equipped with multi-contact male connectors  REDEL SAG SH 1 (only one end of each cable, other ends stay as is with no connector). I do have sample short (only 6 ft long) cable with REDEL connector build/assembled by DSG. In other words DSG has good experience dealing with REDEL connectors. I am ready to provide DSG group with three long cables and (just in case) sample short cable at any time.
Thank you in advance.
Best regards,
                        Youri
