Abstract
IT has frequently been suggested that a linear accelerator could be constructed using a wave-guide consisting of a circular metal tube lined with an insulating tube of dielectric, and several writers have recently published theoretical investigations of this type of wave-guide, as, for example, Frankel1. The performance of a linear accelerator using such a wave-guide is ultimately limited by the power losses which occur in the metal tube and in the dielectric itself, and calculations show that the performance compares unfavourably with other forms of accelerator, such as corrugated wave-guides2. However, some recent theoretical investigations show that the performance should be greatly improved by using a different form of dielectric loading, and that certain practical advantages should also ensue.
