摘要：
The LHC will be supplied with protons from the injector chain Linac2-PS Booster-PS-SPS. The beam must have small transverse emittances to fit into the LHC dynamic aperture, but sufficient intensity to assure high-luminosity operation. Such a beam with a brightness twice the one of present beams is feasible with a scheme involving acceleration of one bunch (instead of five) in each of the four PSB rings to a kinetic energy raised from 1 to 1.4 GeV, and two-batch filling of the PS, Beam dynamics aspects such as how to tackle small emittances under high space charge, optimizing the (time-varying) working point and dealing with stop-bands, the advent of new RF harmonics 1 and 2, how to shape the magnet cycle, are discussed, and results of machine experiments reported. Finally, some open issues as well as ideas for future improvements are discussed.
