5th pass separation
Figure 1: D beam to AR dumplette, +5.5 at AE02. Took a zero-pos here.
Figure 2: Cavity 1 was having trouble getting into RF, so while waiting for the separator expert to arrive, brought up cavity 2 and phased to zero-crossing.
Figure 3: Cavity 1 phased.
Total phase changes: -104 degrees cavity 1, -87 degrees cavity 2.

Figure 5: D beam recirculating
Figure 6: Separator screen. Verniers had to be reduced significantly to achieve proper separation.

"RF separator expert troubleshooting Pass 5 cavity 1 RF now"
xC dp/p higher than normal
Suggested xB Pass 5 optics
Upon discovering that the PRAD target is roughly 14 meters upstream of where it is positioned in CED (which was used to develop the quad settings currently in CED), new optics were developed. Only the last 6 quads (the two triplets) have different values - BdLs and k1 values are below. k1 is largely included in case I failed to translate something properly.
BdL:
MQR2C20 = 31767.09
MQR2C21 = -55339.08
MQA2C21A = 34743.64
MQK2C22 = 33983.76
MQR2C23 = -61624.12
MQK2C24 = 26493.93
