A computer for solving field problems in electron beam devices
Dinnis, Alan Russel
The need is explained for a new type of computer for solving partial differential equations, the Digital Field Computer. The operation of such a machine for solving Laplace's and Poisson's equations is explained and circuits for its realisation, using incremental switching of magnetic ferrite cores, are given. Its operation is predicted by simulation on a Pegasus digital computer, which shows that it solves Laplace's equation correctly.
