英文摘要	the dalian coherent light source (dcls) is a free electron laser (eel) user facility currently under construction in the northeast of china, it is designed to work on high gain high harmonic principle with the capability of wavelength continuously tunable in the euv regime of 50-150 nm. the light source has unique features such as the turntable radiation frequency, wide spectral range, high brightness and peak power, very short pulse time structure, etc. a key diagnostic task in dcls is the on-line source spectral characteristic recording during the source development, and for the definition of the experimental conditions. for this purpose, an online grazing incidence spectrometer with a toroidal mirror and a variable-line-spacing plane grating is designed and presented in this paper to monitor each single eel pulse. a circular stage is chosen to fit the focal curve and to realize the wavelength scanning. this scanning mechanics is simpler and stable. resolving power (lambda/delta lambda) of this spectrometer is better than 12,000 in the whole wavelength range.
