Download or read book Profile of a Relativistic Electron Beam Propagated Through a Linear Wiggler and an Axial Guide Field written by B. Hafizi and published by . This book was released on 1984 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The density and parallel temperature of an electron beam passing through a magnetic guide field and a linear wiggler are determined as functions of distance from the anode. Starting with a given beam emittance and phase space distribution at the anode, single-particle orbits are employed to propagate the beam along the drift tube. Finite gyro-orbit effects induce substantial modulation in density. Additionally, the evolution of an initial spread in the parallel speed of the electrons is sensitively dependent on the wiggler strength and contributes to further density fluctuation. The beam's parallel temperature, a critical factor in determining laser efficiency and gain, is found to increase significantly when the wiggler strength is raised. Keywords: Relativistic electron beams, Directed-beam quality, Propagation through Guide field and Linear wiggler, Density modulation, and Effective temperature.
