[Sbs_gems] Question about BB GEM plan during SAD

[Holly Szumila-Vance]

Hi Nilanga,

We have a few questions about the plan for the BB GEMs during the SAD.


  1.  Currently, they are still running production gas. I’d like to install the gas line filters. Should we keep them on production and take cosmics when we install the filters? Is there any other consideration here?
  2.  Once we’ve installed the filters, I think we want to proceed with having them on nitrogen and figuring out a plan to install the HV divider. I think we currently have one on site. Without beam, are there any other tests that we should perform besides an HV runup? This will probably require lots of coordination with Jessie’s hall work.
  3.  Is there any other work/upgrades/considerations for these GEMs besides the two questions above?

Thanks,
Holly
