Collar pack # 1Choice of the radial shim

• The purpose of this first collar pack was to assess the radial shim size

• HQ 15-16-17 and 20 coils are made with a revised (smaller) cable and are expected to have overall dimensions close to nominal.

• For the record, HQ 15 was tested in HQM04

• Comparison between CMM measurements, nominal collar dimensions led to the adjustment of the radial shim from .036” to 0.032”

• The alignment key was not shimmed during this assembly.

Collar pack # 1 build

• 0.032” radial shim stack made of • Two 0.010” G10 shim => in reality closer to 0.0085-0.009”• One 0.005”G10 shim• 0.007” Low pressure Fuji film • Effective stack 0.0029”

Effective gaps between collars

• 0.032” radial shim stack made of • Two 0.010” G10 shim => in reality closer to 0.0085-0.009”• One 0.005”G10 shim• 0.007” Low pressure Fuji film

• The effective stack was measured to be 0.029“ Þ gap between collar become 0.370”

• Effective gap measured between collars: • 0.365” in straight section

• Would translate in coil oversized in average by only 0.001” per midplane in straight section• 0.354” in the end region

• Would translate in coil undersized by about 0.003”/0.004” per midplane in the ends• Consistent with CMM measurements:

Status on HQ02 collar pack assembly

Collar pack # 1• Consistency between CMM measurements radial shim choice, Fuji paper results, SG data and

initial radial shim • Uniform pressure distribution, could be slightly improved toward the midplane

Collar pack # 2• we will keep the same radial shim or less:

• 2 layers of 0.005” Kapton wrapped around the collars• 2 x 0.010” G10 shim => in reality closer to 0.0085-0.009”• Stack expected ~ 0.027”• The effective stack is 0.028”

• alignment keys shim: 0.021” per side in the straight section based on initial assumption 0.027” radial shim

• Collar pack assembled• SG in compression, • Collar dimensions and gaps measurements ongoing
