Abstract : This report is divided into five separate tasks. Study of Basic Beam Phenomena studies were con ducted on the r-f propagation along a d-c scalloped beam, and progress was made on the development of equipment for measuring r-f propagation along confined-flow electron beams in varying magnetic fields and the growth of noise in scalloped and nonscalloped Brillouin beams. ''Beam-Circuit Interaction,'' analytical work was performed with the aid of an electronic computer on the largesignal properties of two-cavity klystrons and on the properties of biased two-cavity klystrons. Experimental work, along the same line as Hefni, was started on an external cavity klystron, and periodic microwave interaction studies were also begun. ''Nanosecond Pulse Study,'' in which experimental work on the response of klystrons to nanosecond r-f pulses and theoretical studies using nonlinear space-charge wave analysis were carried out. ''Interaction of a High-Power Electron Beam and a Plasma,'' work was conducted on the generation and diagnosis of a hydrogen plasma, on plasma-amplifier gain, on direct coupling mechanisms, and on electron beam stability.
