On Peculiarities of Betatron Oscillations of Accelerated Electron Bunches in Capillary Waveguides
Figure 3
Dependencies on the acceleration length of (a) normalized emittance , (b) root-mean-square radius of the accelerated electron bunch , and (c) average energy gain of electrons during acceleration for matched capillary waveguide. Curves are shown for different energies of injection of electron bunches (see legend). Electrons in accelerated bunches have Gaussian distribution in both longitudinal and transverse directions with dimensionless characteristic sizes and , respectively. Electron bunches are injected at the time at the point at the length of the capillary, with zero initial emittance. The center of the electron bunch is injected into the focusing phase of the wakefield at a distance of from the point of maximum of the accelerating force. Other parameters are the same as for Figure 1.
