【 摘 要 】

We have met this milestone by making measurements of electrons, as described in our FY05 Q3 Milestone Report, and simulating the same conditions with the WARP/POSINST code. This code has been developed over the last three years, by adding self-consistent electron and gas populations to the beam-dynamics particle-in-cell code, WARP, and combining it with the electron-cloud code from LBNL, POSINST. This code development effort has advanced to the point where almost all elements of a comprehensive ''roadmap'' are available. The WARP simulations shown here replicate experimental results, with agreement ranging from semi-quantitative agreement to close quantitative agreement.
