1 HQ & LHQ End Parts Miao Yu Fermilab 08/27/12

2 HQ parts All the spacers are arriving within a week. 2

3 HQ L1 RE Key (Pole) 3 Nominal thickness: mm ( inch) Measure: inch ~ inch

4 Saddle Grind by hand due to the late awareness Not satisfied Our techs will buff the edges (20 min/part) ~14.0 mm vs mm ~0.5 mm unsupported strands during w/c/r 4

5 Spacer The spacers were fabricated after the awareness. 5

6 Plasma Coating 6 Vendor: White Engineering, PA A100 coating passes the curing, reaction and thermal cycle

7 Thickness measurement 5 random points on OD, BEND and side surfaces Fisher dual scope 7

8 Thickness measurement 5 random points on the coating surface 8

9 Quotation 1 9 Equipped with robotic head +/- 1mil on priority surface +/-3mil on curved surface Response: very slow Price: high Delivery: slow

10 Quotation 2 10 Coat manually +/- 3mil tolerance Response: fast Price: low Delivery: fast

11 Quotation 3 11 Equipped with robotic head +/- 1mil on regular surface +/-3mil on BEND surface Response: fast Price: low Deliver: fast

12 Plan 6 middle pole pieces (one LHQ coil) to each vendor Verify the thickness Measure the coating strength as the parts received and after curing, reaction and thermal cycles. (no impregnation test) Vendor selection 12
