[dsg-hallb_rich] [EXTERNAL] Report on the RICH assembly

[Marco Mirazita]

Dear all,
last week we completed the first round of the second RICH module 
assembly.
I want to thank the DSG, in particular Tyler, Marc and George, and to 
Valery for the support they provided during these two weeks.
And a big thank must go to Dario and Sandro, traveling from Italy to USA 
during these days was not easy at all.
Here is a brief summary of what has been done and few words on the plans 
for the next activities, we will have more detailed discussions at the 
next RICH meeting.

1) The RICH vessel has been successfully assembled. This includes the 
installation of the frontal panels, of the electronic panel and of the 
the frame of the tedlar window.
2) The RICH was rotated up and down once, no issues were found.
3) The new procedure to install the electronic panel has been tested; 
besides the fact that few details must be revised, the test was 
successful
4) We didn't have time to do much on the tedlar window except for 
mounting the frame on the RICH; we leave the rest of the work to the 
Argonne personnel
5) The need for a revision of the spherical mirror mounts has been 
identified, we will have a phone meeting with CMA soon to discuss this 
point; after that, the new top part of the mounts can be printed at JLab 
and eventually the mirrors shipped back to CMA

The RICH has been left in horizontal position with the frontal panels 
and the frame of the tedlar window installed. I would ask DSG to cover 
the detector with a plastic sheet to preserve it from dust.
The electronic panel is on its frame, ready for the assembly of the 
boards.
We discussed with Tyler and Marc several items to be purchased for the 
next activities, I will prepare a summary list for the next meeting.
Best regards,
Marco
