Figure caption: Measurement of the convex lens surfaces. Left: diagram of the Convex Surface Interferometric Test Stand. The interferometer, fold mirrors, collimator, and test plate were moved as a unit by the tilting rotary table in order to measure multiple subapertures across the full surface aperture. Right: map of the 12 subapertures covering the 800 mm diameter clear aperture of ADC1. The 19 small circles show the locations of fiducials used for stitching together the subapertures into a full-aperture map. (Credit: Rayleigh Optical Corporation.)

Figure caption: Layout of the C3 convex surface measurement. The “Mangin” configuration measures the total wave-front error of the double-pass transmission and back-surface reflection of the lens. The vendor calculated the convex surface profile from this by subtracting a separate measurement of the concave surface. The configuration includes a custom CGH to remove test aberrations.

Figure caption: Lens cell centers and tilt measurements after the last alignment iteration at FNAL. The left panel shows the centers of the C1, C2, C3, and C4 cells in the barrel coordinate system. The center of this coordinate system was defined as the best fit to the center of rotations of the ADC1 and ADC2 cells. The right panel shows the tip/tilt measurements of all the cells; the double sets of points in this plot correspond to two different measurements, giving an idea of the measurement repeatability errors. The large circles show the alignment requirements. (Left image previously published in Gutierrez et al. 2018.)

Figure caption: Barrel deflections predicted by FEA. Black lines show the deflections at the locations of the lenses and focal plane along the barrel axis. Green lines show deflections after an overall rotation of the barrel to correct average deflections, as is performed by the hexapod. Light-blue bars show the lateral and tilt requirements for the entire corrector. Dark-blue bars show the lateral and tilt requirements due to barrel deflections alone. The FEA prediction including the hexapod correction (green) is within requirements (dark blue). The barrel is in the horizontal position and at a 0° rotation around the barrel axis. Top: lateral deflections. Bottom: angular deflections.

The thickness of the slanted blue bars is labeled B, and that of the straight green bars is labeled b. The angle at the base of the isosceles triangles is labeled θ. The stress−strain relation for the isogrid is given by the expressions on the right, where t, T, E, and ν are the thicknesses of the skin and the grid, Young’s modulus, and Poisson’s ratio, respectively.
