Book Description
A gyrotron traveling-wave amplifier (gyro-TWT) with the high-power and broad-band capabilities is considered as a turn-on key for next generation high-resolution radar. The book presents the most advanced theory, methods and physics in a gyro-TWT. The most challenging problem of instability competition has been for the first time addressed in a focused and systematic way and reported via concise states and vivid pictures. The book is likely to meet the interest of researchers and engineers in radar and microwave technology, who would like to study the gyro-TWTs and to promote its application in millimeter-wave radars. Chao-Hai Du and Pu-Kun Liu are both professors at Peking University.

Book Description
Results of a 1.5 MW, 110 GHz short (3 microsecond) pulse gyrotron experiment are reported. The gyrotron magnetron injection gun operated at full voltage (96 kV) and current (40 A), producing up to 1.4 MW at 110 GHz in the TE22,6 mode. The operation of the TE22,6 mode, as well as nearby modes, was measured as a function of magnetic field at the cavity and at the electron gun to produce a mode map. Significant mode competition was found, but the measured efficiency of 37 % in the TE22,6 mode, without a depressed collector, is close to the design value of 39 %. The beam alpha, the ratio of transverse to axial velocity in the electron beam, was measured with a probe. The alpha value was found to be 1.33 when the gyrotron was operating at conditions for achieving the highest output power level (1.4 MW.) This value of alpha is less than the design value of 1.4, possibly accounting for the slightly reduced experimental efficiency. The output power and efficiency, as a function of magnetic field, beam voltage, and beam current, are in good agreement with nonlinear theory and simulations with the MAGY code. These results are promising for the development of an industrial version of this gyrotron capable of long pulse or CW operation.

Book Description
Although particle accelerators are the book's main thrust, it offers a broad synoptic description of beams which applies to a wide range of other devices such as low-energy focusing and transport systems and high-power microwave sources. Develops material from first principles, basic equations and theorems in a systematic way. Assumptions and approximations are clearly indicated. Discusses underlying physics and validity of theoretical relationships, design formulas and scaling laws. Features a significant amount of recent work including image effects and the Boltzmann line charge density profiles in bunched beams.
