Abstract
The feasibility studies on the transverse RF accelerator are progressing in all areas covered by the contract. The initial estimates have generally been corroborated by our calculations. The electromagnetic fields in the RF acceleratory cavity, a prolate ellipsoid of revolution, were analysed in terms of known special functions. A computer program for these functions was acquired and implemented. We are presently using the program to verify the asymptotic fields used in energy transfer calculations. An analytical calculation of beam loading gave mixed results. The difficulty is that the beam is resonant with the fields, and therefore strongly perturbed; hence the loading problem is fully nonlinear and very difficult to solve analytically. The calculations on front end injection of electron bunches show that large currents in the kilo ampere range can be injected. A laser activated cathode would emit electron bunches which can be laterally compressed without excessive de- bunching. Only minor emittance calculations have been performed to date. Since the electromagnetic fields are now know exactly there should be no trouble with this.
