Calculation and analysis of the magnetic field of a linearly tapered undulator
《Chinese Physics C》2015年第8期99-101,共3页李和廷 郭帆 李佳玉 贾启卡 
Supported by National Natural Science Foundation of China(11205156);Major State Basic Research Development Program(2011CB808301)
There is an empirical formula describing the relationship between the peak magnetic field and the undulator structure parameters for a uniform-parameter hybrid undulator. In this paper, we investigate the relationship...

Physical design of a wavelength tunable fully coherent VUV source using a self-seeding free electron laser
《Chinese Physics C》2014年第5期110-113,共4页李和廷 贾启卡 
Supported by Major State Basic Research Development Program of China(2011CB808301);National Natural Science Foundation of China.(11205156)
In order to meet the requirements of the synchrotron radiation users, a fully coherent VUV free electron laser (FEL) has been preliminarily designed. One important goal of this design is that the radiation wavelengt...
