Abstract

The invention discloses a gradient magnetic field device which comprises a guiding magnetic field for guiding transmission of a high-current relativistic electron beam; the guide magnetic field comprises a solenoid coil; the solenoid coil is wound around the high-current diode so as to form a gradient magnetic field enabling the high-current relativistic electron beam to generate radial deflection, and the solenoid coil comprises a first sub-coil, a second sub-coil and a third sub-coil; the first sub-coil is wound on the outer side of an anode of the high-current diode, the second sub-coil is wound on the outer side of an outer conductor of the high-current diode, and the third sub-coil is wound on the outer side of the second sub-coil; the guide magnetic field further comprises an adjusting magnetic field; and the adjusting magnetic field is fixedly arranged between the first sub-coil and the second sub-coil, is wound around the high-current diode and is used for adjusting the radius change speed of the high-current relativistic electron beam. The invention further discloses a high-current diode based on the gradient magnetic field. The high-current diode comprises the gradient magnetic field device. The problem that the size of a high-impedance diode is difficult to reduce can be solved.

Description

Technical field [0001] The present application relates to a high-power microwave technical field, particularly to a gradient magnetic field and a strong diode device based on the gradient magnetic field. Background technique [0002] HPM (High Power Microwave, referred HPM) generally refers to the peak power is greater than 100MW, frequency of electromagnetic waves is between 1 ~ 300GHz. High power microwave source is a core component of a high power microwave system, intense relativistic electron beam generated by the cathode of the diode that emits explosive (Intense Relativistic Electron Beams, referred IREB) for high-frequency electromagnetic beam and Structure - wave interaction, of the IREB kinetic energy into microwave energy. Thus, diodes IREB system is one of the crucial components of HPM. [0003] The pursuit of higher power, higher frequency, higher efficiency of the microwave output is always an important goal of technology development in the field of HPM. With the im...
