Operation and Expected Performance of the NLC

‘The main linacs for the proposed Next Linear Collider (NLC) provide acceleration of up to 500 GeV per beam. The linacs operate in a regime where unavoidable imperfections and even natural ground motion cause significant emittance dilutions. In order to achieve the NLC luminosity goals, small emittance beams must be transported with an emittance growth of less than SLAC-PUB-7354 November 1996 Operation and Expected Performance of the NLC Main Linacs* Ralph W. Assmann and Tor O. Raubenheimer Stanford Linear Accelerator Center, Stanford University, Stanford, CA 94309, USA about 175% for the 1 TeV center-of-mass version of the NLC. In this paper we discuss the operation and the expected performance of the NLC main linacs. Under the assumption that the specified device tolerances are met, it is shown from detailed simulations that the linac emittance transport fulfills the NLC requirements.
