	Recently the so-called diffraction limited storage ring (DLSR) with emittance around or below 100 pm.rad has attracted worldwide interest and R&D efforts. It has been proposed to build a DLSR in Beijing, named High Energy Photon Source (HEPS). In this paper, we present a latest PEPX-type lattice design of the HEPS storage ring with beam energy of 6 (or 5) GeV and horizontal natural emittance of 88 (or 61) pm.rad. Nonlinear dynamics optimization has been done to ensure an efficient injection and a long enough Touschek lifetime.

	The Emittace growth induced by Coherent Synchrotron Radiation(CSR) is an important issue when electron bunches with short bunch length and high peak current are transported in a bending magnet. In this paper, an optics design technique is introduced which could minimize the emittance dilution within a single achromatic cell. We gave a comparison between this method and the earlier optics method, simulation results confirmed the usefulness of our new result.
