	Funding: Work supported by Department of Energy Contract DE AC03 76SF00515 The pulse energy density of X-ray FELs will saturate or destroy conventional X-ray diagnostics, and the use of large beam attenuation will result in a beam that is dominated by harmonics. We present results at the LCLS from using a pulse energy detector based on the thermal acoustic effect. In this type of detector an X-ray resistant material (Boron Carbide for this system) intercepts the beam. The pulse heating of this material produces an acoustic pulse that can be detected with high frequency microphones to produce a signal that is linear in the absorbed energy.

THPB28	The High Power Test Model of C-band Accelerating Structure for Compact XFEL at SINAP	impedance, linac, wakefield, factory	617
	W. Fang, Q. Gu, Z.T. Zhao SINAP, Shanghai, People's Republic of China D.C. Tong TUB, Beijing, People's Republic of China
	R&D of a C-band (5712 MHz) high gradient traveling-wave accelerating structure is being in progress at Shanghai Institute of Applied Physics (SINAP). Conceptual design of the accelerating structure has been accomplished, and verified by the cold test of the experimental model. Now the first prototype structure is ready for high RF power test and the optimization of a new operating mode is proposed for developing a robust high gradient C-band struture. In this paper, the results of the cold test of the first prototype structure and the optimization details are introduced.
