TL;DR: In this article, a three-mirror traveling-wave resonator was used to create pulse compression using linear frequency modulation of the input pulse, rather than stepwise phase modulation used traditionally.
Abstract: We describe a 34272 GHz pulse compressor based on a three‐mirror traveling‐wave resonator, which creates pulse compression using linear frequency modulation of the input pulse, rather than step‐wise phase modulation used traditionally The results of testing the compressor prototype at a low power level under different modulation methods and different widths of the input pulse are discussed We present also the results of calculations and tests of an electrically controlled diffraction grating, which can serve as the active switch for such a three‐mirror resonator

TL;DR: In this article, results of investigations of many components including resonator passive pulse compressor, controllable launcher for a DLDS system, low-loss miter bends, and mode converters are presented.
Abstract: Efforts are underway within the accelerator community to develop high-gradient RF accelerators using microwave sources at relatively high frequencies (in particular, at 34.272 GHz). Yet no corresponding high-power components providing pulse compression, transmission and input coupling to the accelerating structure are currently available. Results of investigations of many components including resonator passive pulse compressor, controllable launcher for a DLDS system, low-loss miter bends, and mode converters, are presented.

TL;DR: A high-efficiency, high-power magnicon at 34.272 GHz has been designed and built as a microwave source to develop radio frequency (RF) technology for future multi-TeV electron-positron linear colliders as mentioned in this paper.
Abstract: A high-efficiency, high-power magnicon at 34.272 GHz has been designed and built as a microwave source to develop radio frequency (RF) technology for future multi-TeV electron-positron linear colliders. To develop this technology, this new RF source is being perfected for necessary tests of accelerating structures, RF pulse compressors, RF components, and to determine limits of breakdown and metal fatigue. The design of this high-power amplifier tube, as well as the first experimental results are presented.

TL;DR: A brief survey of the status of this Ka-band magnicon and component development efforts can be found in this article, where the authors present a detailed analysis of the current state-of-the-art.
Abstract: Recent commissioning of a 45-MW peak power 34.3 GHz magnicon amplifier makes possible, for the first time, high-power tests of components and structures for a possible future high-gradient millimeter-wave linear accelerator. A brief survey is presented of the status of this Ka-band magnicon and component development efforts now underway.

TL;DR: In this article, the Yale/Omega-P Ka-band magnicon was used to test the stability and repeatability of a high-power accelerator test facility, where steering coils were installed between the gun and the RF system.
Abstract: New results of experimental tests of the Yale/Omega-P Ka-band magnicon are presented. The main goal is to achieve stable and repeatable operation necessary for operation of a high-power accelerator test facility. In order to direct the beam along the tube axis, steering coils were installed between the gun and the RF system, thereby allowing an increase in pulse width and achievement of good stability and repeatability of the output signal. The test facility is briefly described.

TL;DR: In this paper, a high-gradient multi-TeV electron-positron collider is decided to be driven with millimeter waves, and the high-intensity flow might be efficiently controlled by oversized, high-selectivity, quasi-optical components.
Abstract: If a high‐gradient multi‐TeV electron‐positron collider is decided to be driven with millimeter waves, the high‐intensity flow might be efficiently controlled by oversized, high‐selectivity, quasi‐optical components. Two examples are discussed in the paper. The first is an accelerating structure composed of coaxial radially‐corrugated disks, where each cell is fed individually through a sufficiently broad coupler; this structure seems attractive for maximizing the accelerating gradient while avoiding RF breakdown and surface fatigue from pulsed RF heating of metallic surfaces. The second example is a delay‐line‐distribution, pulse‐compression and wave‐flow‐focusing feeder to the structure that could include control and protection components based on use of corrugated mirrors.
