Abstract：
A method is described which experimentally determines the trajectory sensitive parameter β of NdFeB rectangular magnet used for wiggler of Beijing Free Electron Laser(BFEL).The parameter β expresses the contribution of single magnetic block to electron trajectory.The magnetic blocks are chosen and optimized according to their β values, and the deviation of electron trajectory in the wiggler can be improved.
