[Dsg-hallc_nps] [EXTERNAL] Re: SAMTEC connectors

[Aaron Brown]

Hi Brad,

Just to be clear, we shouldn't worry about ordering the SAMTEC connectors until someone at JLab signs off on the NPS chassis connectors boards?
That's fine with me, just wanted to make sure it wasn't going to be a problem if we couldn't order them before the end of this fiscal year.

Thanks,
Aaron

Based on what I've heard from Steve, I think prototypes of the NPS
chassis connectors boards will have to be sent to JLab and tested so
someone here can sign off on it.

I believe that will push the 'NPS side' of the NPS HV connector issue
into the next FY.
