Abstract

At the Los Alamos Scientific Laboratory, a computer program for calculating the nmgaetic and electric fields in resonant cavities has been developed. This program, LALA, will compute the fields in any cavity having cylindrical symmetry; arbitrary shapes for both drift tubes and external boundaries can be treated. Both π-mode and 2π-mode cavities can be handled. Calculations of several π-mode cavities at about 800 Mc/sec frequency have been carried out. At this frequency, for the π-mode, and in a cavity containing a drift tube, an external conducting boundary having a circular cross-section gives about a ten percent increase in ZT2 from the more normal rectangular external boundary.
