MDR1I02 Observations
Was asked to look into MDR1I02 for anything suspicious. Plotted the current and voltage readbacks, nothing notable was observed. The readings are pretty solid over the last couple of weeks. Noise counts are also well below alarm limits. No reason to suspect anything wrong here from a DC Power point of view.
Injector Transmission/interception optimization
We minimized interception on A2 using A beam with the prescribed correctors (MHD0I01AH/V). A1 interception was acceptable, so we did not touch the correctors designated for minimizing interception on A1 (MBH0I01H/V).
Fig. 1 is 45 uA CW for A to the ILD
Fig. 2 is 40 uA CW for C to the ILD
Fig. 3 is A and C combine to the ILD
Orbits for all for beams (Figs. 4-7). Reference orbit is A beam (Fig. 4). The relative orbits for B (Fig. 5), C (Fig. 6), and D(Fig. 7) are relative to A's orbit.

Fig. 1 is A's orbit
Fig. 2 is C's orbit relative to A
Fig. 3 is C's orbit
A and C are collinear. The differences between the A and C orbits are sub-0.3 mm in the horizontal plane and sub-0.6 mm in the vertical plane. These differences are not significant.
