2 Curing Pressure and Control Inner layerOuter layer Mandrel cylinder pressure (pump psi) Platen cylinder pressure (pump psi) Room T gap (mil)02~4 100/150 deg. C gap (mil)0/0 2 Gap was measured between the platen and the curing mold The mandrel pressure 2000 pump psi equals ~2.5 MPa to the coil radially The platen pressure 3000 pump psi equals ~27.5 MPa to the coil azimuthally

3 After curing 3

4 4 120 g Ceramic Matrix Binder was applied to the IL 140 g Ceramic Matrix Binder was applied to the OL Need more binder for OL

5 LE Saddle 5

6 RE Saddle 6

7 Solution 7 60 mil 50 mil SS shim + 20 mil Kapton = 70 mil Coil mid-plane has 5 mil gap Solution: Add 20 mil Kapton to the SS shim upto both end saddles Add 15 mil Kapton to the SS shim along the saddles

12 Saddle Solution Cut slits on the saddles, similar as spacers (RE is fine, LE is not good due to lead) Solution: No modification on saddles, and push saddles in after curing. Grind extra material on the bottom area of the tips, fit the saddles before curing. 12

13 Pole Gap 13 G1 (mm) G2 (mm) G3 (mm) G4 (mm) G5 (mm) G6 (mm) G7 (mm) G8 (mm) Total (mm) Before winding Before curing After curing Before reaction LE RE Before curing, total gap size decreases by mm from mm (2.4%) After curing, total gap size increases by mm from mm (1.6%) Before reaction, total gap size is 9.86 mm, 3.3 mm/m (2.986 m inner layer coil length) Inner layer

14 14 G1 (mm) G2 (mm) G3 (mm) G4 (mm) G5 (mm) G6 (mm) G7 (mm) G8 (mm) Total (mm) Before curing After curing Before reaction LE RE Before curing, total gap size decreases by mm from mm (2.4%) After curing, total gap size increases by mm from mm (1.6%) Before reaction, total gap size 9.35 mm, 3.1 mm/m (2.999 m inner layer coil length) Outer layer
