- Draft agenda is on Ken Long
Field mapping *
Magnet alignment
Optics without M1 at SSD- Luminosity = n^2/emittance_trans
- Scott Berg lattice looks like it performs significantly better in terms of cooling
- Note that SS field is low
- Note that FC current is high
- "Luminosity" parameter does increase 4 %
- (Modified) Ao's had "luminosity" parameter that increases by 1 %
- Rogers "luminosity" parameter did not increase
- Note that coil currents capped at 225 A
- Check coil currents capped for Match coils
- ACTION: Rogers to send Match coil currents to Scott Berg
- Note no momentum spread was used
- Scott will resurrect his histogramming method
