4R steering to minimize 5S IDX.
In our attempts to minimize IDX rates, we had a small amount of success in reducing the 5S01 signal by adjusting the vertical launch into 5L. Unsurprisingly, given the low energy, the beam is very sensitive to magnet changes, and responsive to gang phase. We can minimize the rates with only gang phase, but that smears the beam across the 1A SLM to the point that it's almost invisible. Not ideal. Efforts continue.
