Abstract:

This report covers the first triannual effort of a Research and Development program to design, construct, and test an advanced high efficiency traveling-wave tube designed to amplify multiple signals while minimizing and mixing products which result from non-linear operation. The tube will be operated in the linear region below saturation tube efficiency will be enhanced by means of a four-stage depressed collector. The electron gun was scaled to the proper perveance and area convergence. Parts were ordered to check the scaled gun in the demountable beam analyzer. Preliminary thermal calculations have indicated that the tube can be air-cooled. The iron cavity walls, used in periodic permanent magnet focusing of the coupled cavity circuit, will be laminated with copper. a beam scraper section will also be incorporated for improved thermal dissipation. Parts and fixtures have been ordered to do the impedance matching of the RF interaction circuit. The mechanical design of the four-stage depressed collector has been started. Author
