Measured and expected sigmas are pretty close at AE01 with the match in and the harp swipe at 2C04 looks good enough to attempt a rematch.

Based on the match, the expected sigmas at AE01 are x:0.178 and y:0.612. The swipe is giving us x:0.223, y:0.754.

figs 1 and 2: AE match downloaded, 2C not on design
figs 3 and 4: AE match reverted to design, 2C not on design
figs 5 and 6: AS on design, 2C on design
figs 7 and 8: AE match redownloaded, 2C on design

after several iterations of downloading the AE match and having 2C quads on and off design, we have come to the conclusion that the best outcome is to keep the AE match and revert the 2C quads to design. next step is to perform a new 2C match.

Entry Makers: deirBody: 

AS matching quads were placed on design and a ballpark match was done using 9R V/H Beta quads to get a good beam profile at the AE01 harp. This had promising result and produced a 0.187 x 0.276 profile at the harp (linked ELOG).

A match at AE01 was then attempted and beam got pretty large, Fig 1. However, the expected sigmas from the match at this harp are:

Expected sigmaY at IHAAE01:
sqrt(design_beta*measured_emittance) = 6.1187e-04 +/- 8.8573e-10 m

Expected sigmaX at IHAAE01:
sqrt(design_beta*measured_emittance) = 1.7872e-04 +/- 5.6109e-08 m

At this point, 2C quads were taken back to design and a harp swipe was taken, Fig 3.

Path forward would be putting 2C04 quads on design to see if the profile is good enough to rematch. If it is, attempt to rematch at 2C04.
