Protons at store: contribution from IBS

  • Purpose of this store was to measure polarization during

the store without collisions.

  • At the same time it provided emittance and bunch length

measurements which can be compared with the growth expected from IBS (not a dedicated IBS experiment as we did in the past).

Results: IBS in Yellow beam (bunch intensity N=1.6e11)

simulation bunch length: 34% in 4 hours simulation emittance: 13% in 4 h bunch length measurement: 25% in 4h emittance measurement: 14% in 4 h
