End-of-year talk LIU-SPS BD WG meeting

Our meetings in 2013 O During year - 9 meetings of LIU-SPS BD WG (less than usual 12 in the past :-) O Main topics: O SPS impedance – 17 talks… O Instabilities – 7 talks O Main speakers: O 5 talks: J. Varela, E. S. O 4 talks: T. Argyropoulos, B. Salvant, H. Timko O 3 talks – H. Bartosik, F. Caspers O Main writer: H. Bartosik - thanks a lot for Minutes!

Main efforts O SPS MDs: two months in 2013 and analysis of 2012 data O LIU days O SPS beam parameters – for RLIUP O LIU-SPS reviews (10!) => talks O SPS impedance model O Particle simulations

Priorities for MDs in 2013 ( from meeting on ) O Reference impedance measurements (synchrotron frequency shift) in Q26 with single bunches of: O variable, in range (1-15)x10 10, intensity O constant small (0.25 eVs) longitudinal emittance O Impedance identification: long bunches with RF off in Q20 (very high intensity ~ 8x3x10 10 ) O Single bunch stability in Q26 and Q20 (effect of bunch distribution due to the PS bunch rotation) O Single bunch stability in double RF system (Q26&Q20 => All measurements were done and analysed. Now they should be compared with simulations

B. Goddard LIU-SPS 800 MHz RF 12 December 2013

Plans for 2014 O Beam re-commissioning after LS1 O E-cloud: SPS scrubbing (do we need Ac-coating?) O Preparation of the LHC beam: 50 ns & 25 ns (BCMS) O Pushing intensity of 25 ns beam to the maximum O Preparation of doublets for scrubbing of LHC - new (longer) magnetic cycle - LLRF, transverse damper O SPS MDs O Effort for SPS impedance identification O Space charge studies O LIU day on 11 April 2014

MDs? Injector schedule for 2014

Merry Christmas! Happy New Year!
