THE basic principles of this type of accelerator and the details of a first model producing 0-5-MeV. electrons have already been described in Nature¹. The accelerator here described follows the same general design, and as the phase velocity approaches the velocity of light the ratio of the inner radius of the corrugated guide to the air wavelength tends towards the same limit, namely, 0-2. The length has been increased to two metres with a radio-frequency power of 2-0 megawatts so as to accelerate electrons to the region of 4 MeV.
