STATUS OF THE LHC PROTON BEAM IN THE SPS

by Gianluigi Arduini (CERN-SL)

Thursday 4 Jul 2002, 16:00 → 17:00 Europe/Zurich

SL Auditorium (CERN)

During the 2000-2001 shutdown the SPS has undergone a major hardware upgrade to cope with its role of LHC injector. An impedance reduction campaign, improvements to the RF beam-control systems, and modifications to the injection kicker magnets and transverse feedback were the main items of this upgrade. In 2001 the major obstacle encountered in the achievement of the nominal LHC beam has been the beam induced-electron cloud. This generates both dramatic vacuum pressure increases and fast single and coupled bunch transverse instabilities. The results of the studies performed during the 2001 run and the preliminary observations conducted in 2002 are presented. The performances so far achieved with this high brilliance beam are reviewed.

Organiser(s): Werner Herr / SL Division

Note: Tea and coffee will be served at 15:30 in front of the Auditorium
