Design Studies of Re-Entrant Square Cavities for V-Band Klystrons
نویسندگان
چکیده
V-band Klystrons find applications in satellite communications and 5G technology. Here, we present a Klystron using radial re-entrant square cavities (RRSCs). The RRSCs are easy to fabricate, assemble, align, tune the operating frequency, which significant concerns V-band. We have optimized number of gap for best possible gain bandwidth. eigenmode particle-in-cell (PIC) simulation results CST microwave studio presented. optimum design uses eleven equidistantly placed RRSCs, producing maximum 27.17 dB at 60.1 GHz with bandwidth ∼150 MHz.

Multiple Extraction Cavities for High Power Klystrons*
. The design, performance, and comparison with 2-D computer simulations of an X-band high power klystron amplifier utilizing an output circuit consisting of two uncoupled output cavities are described. It is shown that good efficiency, low RF gap gradient, relatively uniform power extraction from each cavity, and freedom from oscillations due to extraneous modes can be achieved. The change in p...

متن کاملRe-entrant DNA gels
DNA is acquiring a primary role in material development, self-assembling by design into complex supramolecular aggregates, the building block of a new-materials world. Using DNA nanoconstructs to translate sophisticated theoretical intuitions into experimental realizations by closely matching idealized models of colloidal particles is a much less explored avenue. Here we experimentally show tha...

متن کاملRe-entrant Manufacturing Systems
Re-entrant manufacturing systems differ from traditional manufacturing systems in the sense that a job may visit a service station more than once, at various stages of the product development cycle. Several parts at different stages of processing may be in contention for service at the same machine, which gives rise to the need to solve scheduling problems. This document surveys some of the fac...
