Abstract :
We have adapted the POISSON/SUPERFISH codes to run on 486 or 386 PCs. The PC version includes features not found in the standard version, including programs for automatically tuning RFQ, DTL, and CCL cavities; a complex version of the RF field solver; memory allocation for temporary data; many line regions for dividing the mesh into fine or coarse sections; full support for multiple-cell DTL cavities; plotting of resonance-search and transit-time data; and on-line documentation. We modified AUTOMESH to generate self-consistent logical and physical coordinates. This new, more robust code greatly reduces the number of crashes in LATTICE caused by ill-formed mesh triangles along boundaries. The codes solve arbitrarily large problems. Each program allows free-format entry of CON array elements, and provides error checking of user entries. Standard release 4 now uses our root finder and convergence criteria
