The LHC Beam with Suppressed RF Transients

The integrated luminosity of LHC can be increased by improving the reliability and lifetime of the machine components, saving money at the same time. One efficient method of doing this for the high power RF system components is to try and avoid RF power transients caused by each passing beam gap. Additionally klystron power settings may be reduced under these conditions, increasing lifetime even more and saving on electricity cost. These transients can be made to disappear if the bunches of the coasting LHC beam are allowed to settle in longitudinal positions, slightly shifted with respect to the regular positions. This will cause a small jitter in the nominal interaction position and time. We will show here that even for the ultimate beam the worst resulting jitter is very small compared to the bunch-length, hence should cause no problem for the LHC experiments.
