Abstract

In this paper, the authors report on a new regime of free electron laser operation using a helical wiggler field and a reversed axial guide magnetic field. The orientation of the axial field is such as to oppose the electron rotation imparted by the helical field. The 33.3 GHz free electron laser amplifier is driven by a mildly relativistic electron beam (750 kV, 300 A, 30 ns) and generates 61 MW of radiation with a 27% conversion efficiency. The results are compared with those obtained when the axial guide field is in its conventional orientation, where considerable loss of power and efficiency is observed.

Experimental study of a 33. 3-GHz free-electron-laser amplifier with a reversed axial guide magnetic field

Journal Article Conde, M; Bekefi, G - Physical Review Letters; (United States)

We report on a new regime of free-electron-laser operation with reversed axial guide magnetic field, in which the rotational motion of the electrons in the helical wiggler field is opposed by the presence of the uniform guide field. The 33.3-GHz free-electron-laser amplifier is driven by a mildly relativistic electron beam (750 kV, 300 A, 30 ns) and generates 61 MW of radiation with a 27% conversion efficiency. Measurements with the conventional orientation of the axial field show a considerable loss of power and efficiency.

Measurements of the temporal and spatial phase variations of a 33 GHz pulsed free electron laser amplifier and application to high gradient RF acceleration

Conference Volfbeyn, P; Bekefi, G

We report the results of temporal and spatial measurements of phase of a pulsed free electron laser amplifier (FEL) operating in combined wiggler and axial guide magnetic fields. The 33 GHz FEL is driven by a mildly relativistic electron beam (750 kV, 90-300 A, 30 ns) and generates 61 MW of radiation with a high power magnetron as the input source. The phase is measured by an interferometric technique from which frequency shifting is determined. The results are simulated with a computer code. Experimental studies on a CERN-CLIC 32.98 GHz 26-cell high gradient accelerating section (HGA) were carried out formore »« less

Beam transmission in a high-power collective free-electron laser

Journal Article Freund, H - Physics of Fluids B; (United States)

A recent free-electron laser amplifier experiment conducted at the Massachusetts Institute of Technology [M. E. Conde and G. Bekefi, Phys. Rev. Lett. [bold 67], 3082 (1991)] has demonstrated high-power operation without recourse to a tapered wiggler field. The experimental configuration consisted in the propagation of an intense electron beam (750 keV/300 A with a nominal axial energy spread of 1.5%) through a cylindrical waveguide in the presence of both a helical wiggler ([ital B][sub [ital w]][le]1.8 kG and [lambda][sub [ital w]]=3.18 cm) and an axial guide magnetic field ([ital B][sub 0][le]12 kG). The experiment operated with the axial guide fieldmore »« less

Nonlinear simulation of a high-power, collective free-electron laser

Journal Article Freund, H; Ganguly, A - IEEE Transactions on Plasma Science (Institute of Electrical and Electronics Engineers); (United States)

In this paper a comparison is described between the three-dimensional nonlinear analysis and simulation code, ARACHNE, and a recent 33.4-GHz, collective, free-electron laser amplifier experiment at MIT. The experiment has demonstrated power levels of 61 ME ({approx}27% efficiency) without recourse to tapered magnetic fields, using a 750-keV/300-A electron beam with a nominal axial energy spread of 1.5% propagating through a cylindrical drift tube in the presence of a helical wiggler (B{sub w} {le} 1.8 kG, {lambda}{sub w} = 3.18 cm) and an axial guide magnetic field (B{sub 0} {le} 12 kG).
