Steady-state operation of FEL oscillator using phase area displacement wiggler
Abstract
The efficiency of a free-electron laser (FEL) oscillator operated in steady state with a phase area displacement wiggler in conjunction with a storage ring is investigated using one-dimensional numerical simulation code. The linear gain is calculated from an eigenmode analysis of the linearized FEL equations; numerical simulations are compared with theoretical estimates of beam energy loss and beam energy spread due to interaction of electrons with a finite amplitude ponderomotive potential well. The efficiency and the scaling of efficiency with the wiggler and EM pulse parameters are then determined.
