Vacuum and Cryogenics observations for different bunch spacing

Following the observations of high pressure rises induced by an electron cloud building up in the LHC beam pipes, studies were launched with beams with 50 and 75 ns bunch spacing at injection energy and with a ramp to 3.5 TeV (only 50 ns bunch spacing). This talk will summarize the observations made...

description Following the observations of high pressure rises induced by an electron cloud building up in the LHC beam pipes, studies were launched with beams with 50 and 75 ns bunch spacing at injection energy and with a ramp to 3.5 TeV (only 50 ns bunch spacing). This talk will summarize the observations made on the beam vacuum and cryogenic systems for both 50 and 75 ns bunch spacing and with a ramp in energy (only 50 ns bunch spacing). Some extrapolations will be presented based on the measurements. Finally, the decided mitigation solutions and beam parameters to be used for the 2011 run will be reviewed.
