Note: At the November 12, 2019 Modeling meeting , we decided to move the buncher to the midpoint position (between the centerline of the choppers and the centerline of the 2-cell in the booster). The buncher position in the July 2019 layout drawings is not the midpoint position; the buncher is shifted closer to the choppers in the July 2019 layout drawings.

- -QCM was .32" further downstream. so all those interfaces moved.
- -distance between chopper cavities was 59.32", so distance from center of choppers to downstream face of chopper #2 increased from 29.65" to 29.66".
- -buncher, IFY0I06, MB00I06, A3, YAO cavity, A4 all moved slightly downstream.
- -YAO cavity was .37" longer than the design drawing.
