Phase 1 - Photogun Layouts

-sequence just before the gun valve goes like this if possible: bellows + bpm/corr + valve.
-remove the pink rectangular placeholders for quadrupoles
-sequence after Vertical Wien: viewer/cross + bpm/corr + bellows, then pipe that solenoids are attached
-restore gap between the FG solenoids as exists in tunnel today
-sequence after Horizonal Wien: viewer/cross + prebuncher + bpm/corr, then bellows
-if moving valve/DP can upstream a little helps w/layout that's OK, keep subsequent solenoid located as shown

Phase 2 - Booster Layouts

Note: At the November 12, 2019 Modeling meeting [1], 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.

Overall Phase 1 & 2 AIPINJ Layouts

Note: At the November 12, 2019 Modeling meeting [2], 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.
