<div class="x_BodyFragment"><font size="2"><span style="font-size:11pt">
<div class="x_PlainText">Hi Aaron, (et al.),<br>
<br>
Thanks very much for the clarifications. It is clear there is some<br>
confusion here and I really appreciate your notes. I also really<br>
appreciate all the work that has been done by the DSG -- this is <br>
a huge job.<br>
<br>
-----------------------------------------------<br>
Plans/Goals:<br>
-----------------------------------------------<br>
The longstanding goal for NPS has been to have every system (detector,<br>
DAQ, cooling/chiller, slow-control readbacks, LED ssytem, etc) tested<br>
in EEL/108 before the system goes to the Hall.<br>
<br>
The ultimate (practical) deadline for a fully-implemented system in<br>
EEL/108 is January. That gives us time to debug/troubleshoot before<br>
breaking the system down and beginning installation into the Hall in<br>
spring 2023.<br>
<br>
The expectation is for the French group to return to JLab towards the<br>
end of November or early-Dec to complete installation of PMTs and<br>
support any other cabling/internal wiring work needed. This could<br>
include internal connections to the humidity sensors. The humidity<br>
sensors did get installed when they were on-site last month.<br>
<br>
The intent is that when they are done, we should have a mechanically/<br>
electrically complete NPS detector system. (To my knowledge the exact<br>
travel dates for the group are still TBD though.)<br>
<br>
<br>
-----------------------------------------------<br>
Cabling support (not DSG):<br>
-----------------------------------------------<br>
Physically cabling things up is definitely not the responsibility of the<br>
DSG :-) When I was talking about 'hook-up' support, it was in the<br>
context of advice and troubleshooting. I think we're on the same page<br>
there.<br>
<br>
<br>
-----------------------------------------------<br>
LED/VLD support:<br>
-----------------------------------------------<br>
I definitely agree that the as-is drivers for the VLD boards were not<br>
were I had understood them to be back in the summer. My understanding<br>
from some conversations/emails in August was that you folks were in<br>
touch with Bryan Moffit and William Gu to get the drivers where you<br>
needed them to be. There were a flurry of emails between Brian E.,<br>
William, and Bryan M. in late August surrounding some VLD firmware<br>
updates and prototype drivers. The last note that I have was a reply to<br>
Brian Eng on 8/23 confirming use of some hardware and a summary of LED<br>
controls that needed to be exposed to the user. I guess I assumed that<br>
work was ongoing -- has it stalled out?<br>
- Do we need a separate meeting with the FE/DAQ group on this?<br>
<br>
<br>
-----------------------------------------------<br>
Chiller:<br>
-----------------------------------------------<br>
I had forgotten to mention the chiller controls in my earlier email.<br>
I'm glad to hear it is basically ready to go.<br>
<br>
<br>
-----------------------------------------------<br>
Humidity sensor 5V supply:<br>
-----------------------------------------------<br>
The 5V supplies for the humidity sensors will certainly go in the<br>
rack near the MPOD Low-voltage supply. The new power supply cable (4<br>
twisted-pairs) that we discussed can follow the same path from rack.<br>
<br>
<br>
-----------------------------------------------<br>
cRIO question:<br>
-----------------------------------------------<br>
I am a little unclear on the cRIO form-factor, where it will need to be<br>
installed (power, network, cabling requirements, etc.) I'm sure there<br>
are no issues, but I'd feel better if we could move that equipment into<br>
EEL/108 and get it on the Hall C network sometime soon.<br>
- Perhaps we can meet later this week and find a location for the<br>
cRIO gear and 5V supply in our EEL/108 racks?<br>
<br>
<br>
-----------------------------------------------<br>
PV Alarms for chiller/HV/LV/humidity/temp etc:<br>
-----------------------------------------------<br>
Thanks for the update on the PV alarms. I knew BEAST was deprecated,<br>
but I wasn't sure what the current plan was for that.<br>
<br>
All the best,<br>
-=- Brad<br>
