3. Updated schedule on 06/15 07/27/2015H. Felice et al.3 Missing A01 tap on CERN coils All wires coming in the center Tech time off New tech training Weather Roll-over tooling fine tuning Coil assembly tooling load tested, Practice with dummy coils Reduced from 2 to 1 week

4. Updated schedule on 06/19 07/27/2015H. Felice et al.4 Vtap Strain relief of SG wiring Meeting planned on June 24th Starting today

5. Updated schedule on 07/06 07/27/2015H. Felice et al.5 Compensation for different coil size

6. Radial Shim summary 07/27/2015H. Felice et al.6 From coil OR to collarL03C103L05C104 Kapton Ground plane insulation0.005” (0.125 mm) Coil specific shim0 0.002” 0.050 mm 0 0.004” 0.100 mm Fuji paper (Low pressure)0.007” (0.175 mm) G105x0.009”+0.005” (1.3 mm)

7. Coil pack assembly #1 with Fuji paper 07/27/2015H. Felice et al.7 Nominal Radial shim = 0.0639” = 1.624 mm Correction from CMM Radial shim should be: 0.064”-0.0025”=0.0615” Actual stack in MQXFSD1= 0.062” = 1.57 mm from coil OR to collar IR: 0.005” ( coil GPI kapton) + 0.007” (Fuji) + 5x0.009”+0.005”(G10) Used for MQXFS1

8. 1 st collar pack 07/27/2015H. Felice et al.8 Coil L05 Coil L03 Coil C104 Coil C103 During assembly SG show very slight compression Coil C103 shows slight tension Lower compression of coil 103 Despite distributed pressure, all coils show higher compression points at the pole

9. 1 st collar pack 07/27/2015H. Felice et al.9 Coil L05 Coil L03 Coil C104 Coil C103 During assembly SG show very slight compression Coil C103 shows slight tension Lower compression of coil 103 Despite distributed pressure, all coils show higher compression points at the pole

10. Coil pack assembly with Fuji paper 07/27/2015H. Felice et al.10 1 st MQXFS1 collar pack Actual stack in MQXFSD1= 0.062” = 1.57 mm from coil OR to collar IR: 0.005” ( coil GPI kapton) + 0.007” (Fuji) + 5x0.009”+0.005”(G10) Used for MQXFS1 2 nd collar pack build High compression at the pole => coil oversized wrt collar Removal of 1 mil radial shim 0.007” Fuji replaced by 0.005” G10+ 0.001”Kapton Alignment keys not shimmed No Fuji diagnostic but SG diagnostic sensitive enough to monitor the change

11. Updated schedule on 07/27/2015 07/27/2015H. Felice et al.11 Repair Coilpack started today Incident
