ABSTRACT We investigated the foundations for high-frequency vacuum electron devices experimentally, with emphasis on deep etch X-ray lithography: lithographie, galvanoformung, abformung (LIGA) to fabricate a miniaturized interaction circuit and a photonic crystal (PC) resonator to excite a stable high-order mode. The successful operation of a LIGA-fabricated folded-waveguide traveling-wave tube was reported. From such physical considerations as Debye length and photonic band gap, we proposed a reflex klystron adopting a cold cathode and a PC resonator.

    ABSTRACT: Results of the theoretical analysis of the diode oscillator with a field-emission cathode placed in a photonic crystal resonator are considered. The analysis of conditions of self-excitation in the small signal approximation is carried out. The nonstationary numerical model of the oscillator based on the nonstationary equation of excitation of the resonator and the particle-in-cell method is developed. Numerical simulation of the processes of oscillation build-up is performed. The simulation shows rather high output power and efficiency for reasonable values of cathode current density.

    ABSTRACT: This paper presents the design of an electron gun for terahertz vacuum tubes realized with a nanowire or nanotube cold cathode. This technology is particularly interesting in this field since it allows the reduction of gun dimensions and of power consumption with respect to the thermionic guns. We found that focusing is a rather critical aspect since cold cathodes show a relevant transverse velocity, which increases the divergence of the beam and typically induces high current losses on the anode. An analysis of the parameters that influence the transverse velocity has been performed together with the identification of a proper design procedure that reduces the transverse velocity effects. Dif- ferent electron guns have been designed that deliver a circular beam in the range of 1-4 mA with a radius in the range of 30 µm.

    ABSTRACT: In linear vacuum tubes (klystron, TWT) as the operation frequency increases up to THz range, the required beam current density into the interaction structure drastically increases up to 100-1000 A/cm2 [1], leading to a required beam dimension in the order of few tenths of micron [2]. As consequence of these requirements, an intense effort has to be made to shrink the electron gun dimensions. When the geometrical size of the electron gun parts, such as the focusing grid or the anode, are in the range of few millimeter or less, the realization and assembly tolerances, in the order of some tenths of micron, could become unacceptable.
