S-Band Microwave System. Revision
Abstract
This report presents the basic material that was used to develop the cavity design. A partial reference list is included concerning only those aspects that are fundamental to the problem. From this, we have refined our understanding of the interface conditions between the plasma, the plasma envelope, and the waveguide. Factors such as the latter, however, must not dictate the cavity design because such high sensitivity would not permit stable operation. The design has been based on the ability to adapt to all reasonable modifications such an experimental system might encounter. To this end the structure is a large diameter cavity containing a number of longitudinal half wave periods. Both standing waves and travelling waves can be introduced. Linearly, lavio and dextro rotary circularly polarized waves can be introduced. The cavity size is sufficiently large to permit insertion of various potential configurations such as involve the increase in the, in-guide, wavelength, loosley coupled consecutive 1/2 wave cavities, slow wave structures and conical cavities. The reflectivity of the interior of the microwave cavity is sufficiently high to reduce the radiative transfer between the microwave cavity wall and the plasma envelope.
