Update on UVa GEM commissioning (Kondo)
- HV test on N2 of the 4 modules of layer#2 done OK again see link: https://hallaweb.jlab.org/dvcslog/SBS/266 - Plan to do HV test of the GEMs or layer#1 on the cosmic stand again and then move layer#2 on the cosmic stand as well - 34 UVa long cables for layer#2 + a set of MONO cables for one module delivered - We will have to setup a standalone test bench of backplane + APVs before mounting on the chambers (see Siyu's slides) - First versions of the backplanes support on the Alu frames 3D printed => Need small modifications about dimensions => second iteration underway - Got long HV cables from Bogdan for the Clean room GEM layers - Need someone for the test of the divider and PMT for these modules with the help from Bogdan - We start assembly of PREX GEMs (Siyu) => will keep us busy for the next 3 weeks => delay the UVa GEM layer assembly.
