	Funding: This work was supported by the National Natural Science Foundation of China (Grant No. 10935011). As a test facility for modern FEL R&D, The Shanghai deep ultra-violent FEL (SDUV-FEL) is now under upgrading for the cascading two stage of HGHG experiment. It is found that this upgraded facility will be also well suited for the echo-enabled staged harmonic generation (EESHG) scheme demonstration. With help of 3D simulation codes, design studies on the FEL physics for both these two schemes based on the upgraded SDUV-FEL is presented in this paper.

WEPA20	Designing a Pulse-resolved Photon Diagnostic System for Shanghai SXFEL	374
	Y.Q. Wu, J.H. Chen, J.N. Liu, R.Z. Tai, D. Wang, R. Wang, C.F. Xue, G.F. Zhao SINAP, Shanghai, People's Republic of China
	It is presented the design of photon diagnostic system for SSRF-XFEL, the X-ray Free Electron Laser facility in Shanghai Synchrotron Radiation Facility. The system mainly includes a diagnostic beamline with two branches and some diagnostic devices. In the direct passing branch, the intensity distribution of the spot is measured. A set of multi-slit plates are applied for measuring the spatial coherence of a single FEL pulse; In the deflecting branch, a high-resolution VLS-PGM type monochromator, with a simple manual adjusting system, is set up for detecting spectrum of single FEL pulse. The measuring range of wavelength is 45nm-3nm. A fast responding EUV CCD ensures a high pulse resolution to 100Hz.
