FEL efficiency improvement with magnetic field increasing wiggler has been- investigated.-Numerical simulation with KMR equations considering space charge effect we find that FEL power increase greatly.It is interested that the larger the energy spread is,the greater the FEL power increasement is.Therefore the-whole electron beam of the accelerator can be used for FEL and higher power can be gotten with magnetic field increasing wiggler.
