Description
Both single- and multi-bunch instabilities have been encountered in the process of increasing the intensity of the beams in LEP. A survey of measurements made to date on single-beam collective phenomena is presented. They include the dependences of coherent transverse and longitudinal mode frequencies, bunch-length and other beam parameters on intensity. Estimates of the longitudinal and transverse impedances have been obtained as fits to model impedances. The factors limiting the intensity of the beams in LEP are discussed in the context of instability theory. The results with expectations are compared and comments are given on the extent to which customary theories and models have been tested in the parameter range of LEP. (author) 14 refs
