Abstract	A new high-brightness lattice for the NSLS X-Ray Ring is presented. The horizontal emittance of the X-Ray Ring can be reduced by a factor of two to three by allowing nonzero dispersion in the insertion device straight sections and by better controlling the periodicity of the dispersion. Beam was stored in a low emittance lattice during machine studies. The dispersion in the operations lattice lacks the 8-fold periodicity of the magnet structure, because the orbit is offset in the sextupoles. During machine studies the focusing effect of the sextupoles was compensated using trim supplies on the quadrupoles in the dispersive straight sections. Measured results will be presented. A discussion of the hardware upgrade requirements that would be necessary to run the low emittance lattice in operations is also included.
