We have investigated the characteristics of the electron beam (e-beam) in the miniaturized free electron laser module by using the commercial 3D simulation tool OPERA. The e-beam was made parallel before entering the slit-type wiggler by the negative bias applied to the central electrode of the electron lens. With respect to the different structures of the wiggler, we obtained the inner distributions of the electrical potential and the electric field, which was, in turn, used to calculate the trajectory of the e-beam in the wiggler.Key Words : Structure of wiggler, Electron beam, Microcolumn, Free electron laser, THz Source   2010 ()      (No. 2010-0016331) *  : (sjan@sunmoon.ac.kr) 11 01 25  11 02 21  11 03 10 1.
