Run Planning Meeting Notes, December 16 - December 22, 2021
From GlueXWiki
Thursday December 16
- Last 24h:
- Smooth production on LD2 at 140 nA, 0/90 para and perp. Interrupted only by search for better spot on diamond (~1h see below) and ~1h of RF-related down time.
- Issues
- JD70-105 degradation: Hovanes tried to find a new location that improved the 0/90 para and 45/135 para/perp coherent peaks, but to no avail.
- Rates are ~10% lower compared to previous LD2 data taking period, see here. Part of it is lower transmission but even accounting for this, normalized rates remains 6% lower (see trigger/PS, black disk symbols, here).
- Plans
- Continue running on LD2 at 140 nA, 0/90 para and perp.
- Discussion on possible target change to L4He.
- Status of possible CPP test.
