Abstract:

A theoretical treatment was developed on the interaction of a filamentary electron beam with the fields of a Cuccia coupler. This treatment shows that within the region occupied by the coupler there is an electron disturbance that propagates with infinite phase velocity synchronous with the circuit velocity as well as the fast cyclotron wave, slow cyclotron wave, and synchronous wave synchronous with the beam velocity. The electronic admittance of the coupler was computed and plotted in terms of normalized variables as a function of frequency, with coupler length as a parameter. For a long coupler, it is found that the electronic admittance corresponds to that of a resonant circuit, resonant at the cyclotron frequency and having a Q that is directly proportional to the coupler length and inversely proportional to the cyclotron wavelength. The constant of proportionality is pi3. Some properties of slow-wave couplers were also investigated. Author
