Title:
KLYSTRON DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/196648
Kind Code:
A1
Abstract:
Provided is a klystron device with improved output conversion efficiency. The klystron device includes a klystron body and a focusing magnetic field device. The klystron body includes an electron gun part, a collector part, multiple cavity resonators, and multiple drift tubes. The cavity resonators each have nose sections that are opposed to each other in the axial direction and form a gap section communicating with a drift tube. At least one of the cavity resonators has, in portions of the nose sections, electric-field correction sections that make the interval in the gap section different from the interval between the nose sections.
