  1. Solid/EIC GEM prototype assembling @UVa Yuxiang Zhao, Kondo Gnanvo, XinzhanBai, Chao Gu, NilangaK.Liyanage

  2. Design of Solid/EIC prototype • First 2D readout Chamber with this size • COMPASS-like 2D stereo angle (12°) U/V readout • Pitch = 550 μm, top strips = 140 μm, bottom = 490 μm

  3. Frames and GEM foil Spacers: 300μm Extra frame material for the alignment and to hold the tension on GEM foil during assembly  cut out after GEM foil: 32 sectors on top, 16 each on 2 sides 2 sectors on bottom, 1 each on 2 sides

  4. Preparation for assembling---I • Clean and Coat the epoxy frames

  5. Preparation for assembling---II • HV test for GEM foil in a box filled with N2 • For each sector, 550V  ~1nA

  6. Assembling---step 1: paste the 2mm frame onto the readout board

  7. Assembling---step 2: stretch the GEM foil and paste 2mm frame onto the foil

  8. Assembling---step 3: HV test for the foil again and paste it onto the base got in step 1

  9. Assembling processes Step 1: page 6 Step 2: page 7 Step 3: page 8

  10. Solid/EIC prototype HV Divider And HV distribution board

  11. Gas flow Gas Mylar foil Drift cathode 3mm GEM 1 2mm GEM 2 2mm GEM 3 2mm 2D Readout foil

  12. Status of Solid/EIC prototype • Just arrived at Fermi lab • Will flow with N2 gas for several days • Setup for the beam test beginning at 1st OCT.
