Abstract

The Beijing FEL is a rf linac based facility designed to work in the IR spectra range. In this paper, the design consideration and system layout are briefly reviewed first, and then various measures adopted to optimize the electron beam quality to satisfy the lasing requirement are described. Spontaneous emission, stored spontaneous emission and lasing were observed in sequence. The optical spectrum, detuning curve and wavelength shift were measured to confirm first lasing. Further work to be performed is indicated.

Abstract

An intense current RF-linac for the far-infrared FEL is now under construction at CIAE. The normalized brightness of 3.4 x 10{sup 9} A/(m-rad) was obtained from the injector of the linac. An acceleration section with 9 cells will be connected with the injector to provide an electron beam for the 200 {mu}m FEL oscillator. In this paper, the late results from the injector beam test will be reported. The physical design and research progress in the acceleration section, beam transport, undulator as well as optical cavity will be introduced respectively.
