Report of the 1995 bunch train study group

In order to raise the luminosity LEP was operated in 1995 with four equidistant trains of bunches in each beam, instead of the usual four or eight single bunches. Each train consisted of up to four bunches. The bunch spacing was about 74 m. A comparison is made between the plans and expectations in...

description In order to raise the luminosity LEP was operated in 1995 with four equidistant trains of bunches in each beam, instead of the usual four or eight single bunches. Each train consisted of up to four bunches. The bunch spacing was about 74 m. A comparison is made between the plans and expectations in the 1994 Bunch Train Report, and the actual implementation and observations in 1995. The observations made during machine development sessions and during routine operation for physics are discussed. The effects of the scheme on the background in the LEP experiments are anlysed. The performance of LEP equipment, in particular of beam instrumentation electrostatic separators, and the RF systems is presented. The plans for running LEP with bunch trains in 1996 are briefly outlined.
