The surface motion of a gold-coated Mylar pellicle was measured interferometrically while the pellicle was subjected to bombardment from a 15-MeV, 40-mA pulsed electron beam. No surface motion as large as 0.3 microm was observed during the electron p

At the University of Maryland, we have been developing high‐power coaxial gyroklystrons. Our present work is focused on the development of a 17.136 GHz four‐cavity frequency‐doubling gyroklystron amplifier. This device will then be used to driv

We describe results from the initial operation of our coaxial gyroklystron experiment, which is being evaluated as a potential driver for future linear colliders. The interaction is designed to occur between a 500 kV, 500-700 A beam and a series of c

In this paper we describe the present status of the gyroklystron program at the University of Maryland. We are presently studying multi-cavity gyroklystron microwave tubes as possible drivers for future linear colliders. A 3 cavity second harmonic ci

As is known, coaxial circuits can provide a better mode selectivity than cylindrical ones. They also allow for eliminating so‐called ‘cross‐talk’ between gyroklystron cavities operating in high‐order modes. Therefore, in present 100‐MW sc

Two designs of Ka-band 34.2 GHz three-cavity coaxial gyroklystrons that might be applied to driving high gradient linear accelerators are presented. The input, buncher and output cavities operate in the TE011, TE021 and TE041 modes, respectively. The

In order to obtain the high mode purity of a TE011 mode in an overmoded gyroklystron input cavity while maintaining high coupling efficiency, a coaxial dual-cavity input structure with an outer TE411 mode and an inner TE011 mode coaxial cavity has be

A quasi-optical version of the ring cavity pulse compressor is considered. This concept is based on the coupling of the input wave to a whispering gallery mode of a barrel-like cavity due to helical corrugations of the cavity wall. Low-power tests of
