Optical design of the Rapid Cycling Medical Synchrotron

The optical design of the Rapid Cycling Medical Synchrotron (RCMS) is based on the strong focusing principle. Several advantages arise from this choice of design, including smaller beam sizes and more optimization possibilities. In this paper, a detail description of the optical design of all beam lines of the facility is presented with the methods that have been used to optimize such beam lines. Comparisons between old designs and the most recent design will be presented to illustrate the progress in the methods that have been developed for optimization. Special emphasis is made on cost savings when comparing one design with another.
