Efficiency enhancement of free electron Maser oscillator by mode selection with a prebunched electron beam
We present a method for enhancing the efficiency of a Free Electron Laser Maser oscillator by locking it to a preferred resonator mode. This is done by prebunching of the e beam before injection into the wiggler. In a free running oscillator, the longitudinal mode that dominates the mode competition process during the oscillation buildup period is usually the highest gain mode. However, this mo...
متن کاملFree electron maser experiment with a prebunched beam
An experimental project aimed at demonstrating Free Electron Maser (FEM) operation with prebunching is under way at Tel-Aviv university. The FEM utilizes a 1.0 A prebunched electron beam obtained from a microwave tube. The electron beam is bunched at 4.87 GHz and is subsequently accelerated to 70 keV. The bunched beam is injected into a planar wiggler (B, = 300 G, A, = 4.4 cm) constructed in a ...
متن کاملSuper-radiance in a prebunched beam free electron maser
It is well known that electrons passing through a magnetic undulator emit partially coherent radiation: `Undulator Synchrotron Radiationa. Radiation from electrons, entering the undulator at random, adds incoherently. If the electron beam is periodically modulated (bunched) to pulses shorter than the radiation wavelength, electrons radiate in phase with each other, resulting in super-radiant em...
متن کاملEfficiency Enhancement in a Tapered Free Electron Laser by Varying the Electron Beam Radius
3 Paul Scherrer Institute, Villigen PSI, 5232, Switzerland Abstract Energy extraction efficiency of a free electron laser (FEL) can be increased when the undulator is tapered after the FEL saturation. By use of ray equation approximation to combine the one-dimensional FEL theory and optical guiding approach, an explicit physical model is built to provide insight to the mechanism of the electron...
متن کاملLimitations of Electron Beam Conditioning for Free-Electron Lasers
Several ideas have been proposed to ‘condition’ an electron beam prior to the undulator of a Free-Electron Laser (FEL) by increasing each particle’s energy in proportion to the square of its transverse betatron amplitude. This conditioning enhances FEL gain by reducing the axial velocity spread within the electron bunch. We demonstrate that for symplectic beamlines, and independent of the metho...
