Abstract
75779S Both U.S. and European scientists are evaluating the use of permanent magnet wigglers to reduce emittance in the damping rings linear colliders. This project will address two problems related to this approach: (1) nonlinear magnetic fields and transverse roll-off can disrupt the beam quality and damage the wiggler, and (2) electron cloud build-up. During Phase I we will analyze two novel approaches. In Phase I, two novel approaches to reduce transverse roll-off and nonlinear field effects were analyzed using magnetic field analysis software. The analysis demonstrated performance could be improved by a factor of 40 with a 50 percent reduction in magnet costs. In Phase II, protypes will be built and verification tests will be performed to validate the Phase I analysis. Commercial Applications And Other Benefits as described by the awardee: Besides addressing the problem of transverse roll-off and nonlinear field effects in colliders, the linearized wiggler should also be less expensive to build. This reduced cost should directly benefit other applications of wigglers, such as in synchrotron storage rings, industrial processing, medicine, and academia.
