Abstract: Electron ray tracing of an electron-optical system has been implemented on the vector pipeline supercomputer CRAY X-MP. The numerical methods used consist of the integration of the three-dimensional differential trajectory equation d^2r/dt^2=-(e/m) (E+dr/dt×B) and of the calculations of the static field E and B. Most time-consuming part is the E calculation by the surface charge method which is one of the integral methods based on the Green function. A big reduction of the computing time is achieved on CRAY by a vectorization of this part. The numerical methods, the vectorization techniques, and the timing results are described.
