So far, several electron beam test experiments of corrugated structure were carried out on LINACs at PAL and BNL. More recently, a passive control experiment of FEL spectrum, by using a pair of corrugated planes at SDUV-FEL is proposed, which is expected as the first real FEL experimental demonstration of such wakefield structure applications. The physical design, numerical simulations, the vacuum chamber manufacture and the experiment results are described in this paper.

	The RF parameter design of a micro-pulse electron gun (MPG) should be inclined to benefit both the resonance condition of multipacting effect and beam quality, and in particular it is found that the axis electric field of cavity is essential to yield high quality beams. The high RF power density is delivered to the cavity by a small hole in the top of cavity. The size of coupling hole is carefully regulated to overcoupling by using CST MW. Also the configuration of whole gun is presented. Because of its simple structure and operation, the MPG will play a major role in some cost-effective accelerating systems.
