dc.descriptionWe compute the expected number of quasars multiply imaged by cluster size dark halos for current wide field quasar surveys by carrying out a large ensemble of ray tracing simulations through clusters from a cosmological N-body simulation of the LCDM cosmology. Our calculation predicts ~ 4 quasar lenses with splittings theta > 10" in the SDSS spectroscopic quasar sample, consistent with the recent discovery of the wide separation lens SDSSJ1004+4112 which has theta=14.6". The SDSS faint photometric quasar survey will contain ~12 multiply imaged quasars with splittings theta > 10". Of these, ~ 2 will be lenses with separations theta > 30", and ~ 2 will be at high redshift (z ~ 4).
