ULTRA HIGH POWER TRANSMISSION LINE TECHNIQUES
Abstract
The ultra-high power transmission line techniques including both failure mechanisms and component design are discussed. Failures resulting from localized regions of heated gas were studied and a more general equation for breakdown was derived to show the effect of the size of the region. Similarly small obstacles produce regions of high field strength; but the presence of these very small regions become evident only at high pressures or with high dielectric strength gases. Among the other subjects reviewed from earlier reports is the experimental study of the factors effecting arc movement in a waveguide. In view of the many advantages of the low loss mode in circular waveguide for ultra-high power levels, a mode transducer and a two section mode filter or suppressor were designed and constructed. The short compact transducer has a bandwidth more than 8 percent and it can handle 25 percent of the peak power of a standard rectangular wave guide. Water cooling is provided for high average power operation. Analysis of mode sup pression as related to failure of waveguide systems indicates that an equivalent one way attenuation of 5 db is a practical value of attenuation for a mode suppressor where high average power levels are involved. Where only high peak powers are involved lower levels of attenuation are sufficient.
