Multiresolution Simulations of Photoinjectors
We report a successful implementation of a three-dimensional wavelet-based solver for Poisson's equation with Dirichlet boundary conditions, optimized for use in particle-in-cell beam dynamics simulat...

Thisis a numerical study of the effects of a rotationalmismatch of a beam at injection. A closely related typeof mismatch is the presence of a skew quadrupole atsome place in the transporting channel. In both cases, theinitial mismatch implies that the emittance of the beam willincrease as the beam is transported through an alternating focusingchannel. In our simulations, we used the WARP computer codeto simulate the University of Maryland Electron Ring (UMER) beamand we have indeed seen a substantial emittance growth (bya factor of 2–3) for mismatches of 10 degrees. ©2006American Institute of Physics
