Abstract:

The investigation of cyclotron-synchronous wave r-f to d-c power conversion is continuing. Further analytical evaluation and preparation for experimental evaluation are reported. A Pierce-type electron gun and a 3GHz Cuccia cavity have been designed. A collector of low secondary-emission coefficient is being constructed. The electron gun and collector will be pretested in a gun-collector tester also being constructed. A simple analysis of the conversion problem assumes a discontinuity of the B sub z field at z 0. This analysis predicts the asymptote values of conversion efficiency obtained in earlier computer solutions for short transition length. Another simple analysis, using results from a Hamilton-Jacobi investigation of the conversion problem, is given to show why the power converter is linear in operation as an a-c power supply, a result already obtained experimentally. The results of these analyses have indicated a definite direction for the experimental evaluation of the fourth tube. Both reversed-field conversion possibilities and a-c operation will be investigated when the new tube is ready for tests. Author
