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. In the next sections, they will discuss the limitations and assumptions leading to these higher luminosity parameter sets. The details in their discussion will be based on the NLC design described in the Zeroth-order Design Report (ZDR) but the same arguments, with slightly different values, could be applied to the JLC reference design.
