High Luminosity Options for the JLC/NLC at 500 GeV cms

摘要

The present JLC/NLC parameters are chosen to provide luminosities between 0.5 (approx) 0.75 x 10(sup 34) s(sup -1) cm(sup -2) at a cms energy of 500 GeV$ the parameters are listed in Table 1 for both the 500 GeV and 1 TeV cases. In all cases, these luminosities assume extensive margins and emittance dilutions to ensure that they are attainable. In this note, they consider the feasibility of substantially higher luminosities which might be attained by operating with smaller emittance dilutins and higher beam currents. The parameters they describe are listed in Table 2 where these high luminosity sets (ILC-IHa and ILC-IHb) are compared with the base JLC/NLC set (ILC-Ib) and with the high luminosity TESLA parameter set.
