Revision as of 08:58, 2 December 2021

Thursday December 2

Last 24h:
- Established beam last night before midnight.
- Harp scan extrapolation looks to be focused a bit differently than before. PS rates seemed around 3.2kHz as before with 150nA beam so we kept this.
- Radiation levels at 50nA acceptable.
- Continued production on C target at 150nA. Beam not available for most of Early Riser shift so far.
Issues:
- Rates came back lower [1]
- Tagger magnet came back at slightly lower field [2]
Plan:
- run on carbon at 150nA´
- Rotate the radiators and use both configurations
1. - Stop the beam ALWAYS before changing the radiator configuration (even with the same radiator). Between radiator change (0/90 <--> 35/145) ALWAYS ask MCC to insert the dumplette.
