AI Technical Summary
Technical Problem
Existing gyrotron designs suffer from inefficiencies due to E×B drift of electrons, leading to reduced output efficiency and potential damage to components.
Method used
A gyrotron design incorporating a shield within the main body container that maintains the same potential as the transmission mirror, preventing E×B drift by shielding the electron beam and reducing potential differences between components.
Benefits of technology
Enhances gyrotron efficiency by minimizing electron beam loss and preventing component damage, allowing for improved power output and reduced equipment size and cost.

Abstract
To suppress reduction in output efficiency of a gyrotron.SOLUTION: A gyrotron 10 comprises a cavity resonator 16 for generating electromagnetic waves 30 by interacting with an electron beam 28, a collector 26 on which the electron beam 28 passing through the cavity resonator 16 is incident, a main body vessel 40 having an output window 24 positioned between the cavity resonator 16 and the collector 26, an output mirror 22 (or a first mirror) arranged inside the main body vessel 40 and reflecting the electromagnetic waves 30 toward the output window 24, a transmission mirror 20 (or a second mirror) arranged inside the main body vessel 40 and reflecting the electromagnetic waves toward the output mirror 22, and a shield 42 having the same potential as the transmission mirror 20 and cylindrically extending in the traveling direction of the electron beam 28 on the outer periphery of a range including a region where the electron beam 28 passes and the transmission mirror 20.SELECTED DRAWING: Figure 1
