چکیده

We report measurements of millimeter wave emission from a rippled-field magnetron (crossed-field FEL). This is a novel source of coherent radiation in which electrons move in quasi-circular orbits under the combined action of a radial electric field, a uniform axial magnetic field and an azimuthally periodic wiggler magnetic field. We observe %300kW of RF power in a spectral line whose frequency can be continuously varied from I32 to %45 GHz by varying the axial magnetic field.

PFC / JA - 93 - 16 Electron Distribution Function Measurements on a Magnetron Injection Gun Beam

The parallel electron distribution function has been measured on an electron beam from a magnetron injection gun (MIG) using an E 11 B energy analyzer. The magnetic field, beam voltage and beam current were scaled down from normal operating parameters. The perpendicular velocity spread, inferred under the assumption that the electrons are mono-energetic, is relatively constant for electron velo...

PFC / JA - 82 - 33 Cross - field Free Electron Laser Instability for a Tenuous Electron Beam

The free electron laser instability is investigated for a tenuous circulating electron beam propagating perpendicular to a uniform magnetic field B 0 , and transverse wiggler field modeled by B. sin ky, in planar geometry. Unlike the rippled-field magnetron which operates at Brillouin flow, the present analysis assumes a low-density electron beam with w. 4D '. Making use of a macroscopic cold-f...

Preprint PFC/JA-81-19 TWO-STREAM, FREE ELECTRON LASERS

Two parallel, relativistic electron streams with different velocities support unstable, exponentially growing space-charge waves, and efficient electron bunching may be achieved in the submillimeter wavelength range. Injection of the prebunched streams into a static, periodic (wiggler) magnetic field enhances the intensity of the parametrically excited, back-scattered electromagnetic wave. Calc...
