Long-Lifetime Insulation Supporting Board in Tesla-Type Generators

Liang Zhao, Jiancang Su, Rui Li, Jie Cheng et autres

A MV-class SF6-insulated supporting board (ISB) for Tesla-type generators is proposed, which has advantages of compact structure and light weight, but its lifetime is short, only 30,000 pulses. Therefore, various techniques are employed to prolong the lifetime, which include grooving on the …

Prolonging the lifetime of a compact multi-wire-layered secondary winding in the Tesla transformer

Liang Zhao, Jiancang Su, Rui Li, Jie Cheng et autres

A compact multi-wire-layered secondary winding for the Tesla transformer was proposed by Zhao et al. [Rev. Sci. Instrum. 88(5), 055112 (2017)]. The basic idea is to wind multiple layers of a metal wire around a polymeric base tube. However, the lifetime of …

Passive and Dynamic Phase-Change-Based Radiative Cooling in Outdoor Weather

Xiudong Xu, Jinxin Gu, Haipeng Zhao, Xinyuan Zhang et autres

Radiative cooling has attracted considerable attention due to its tremendous potential in exploiting the cold reservoir of deep sky. However, overcooling always occurs in the conventional static radiative coolers because they operate only in the cooling mode in both hot and cold. …

Enhancement of Radiative Cooling Effect by Bioinspired Hollow-core Triangular Structures

Ke Li, Tianshun Zhang, Lei Pan, Xinyuan Zhang et autres

Abstract Inspired by the curiousness that what happens if the silver ant’s hair is designed to be hollow-core rather than solid-core while maintaining its triangular shape, the thermoregulatory response of both the solid- and hollow-core schemes are investigated comprehensively in a photothermal …

Daytime radiative cooling has attracted considerable attention recently due to its tremendous potential for passively exploiting the coldness of deep-sky as clean and renewable energy. Many advanced materials with novel photonic micro-nanostructures have already been developed to enable highly efficient daytime radiative …

5-GW Tesla-type pulse generator based on a mixed pulse-forming line

Rui Li, Jiancang Su, Binxiong Yu, Jie Cheng et autres

To shorten the length of the pulse-forming line (PFL) and generate pulses with good flat-top quality, a 5-GW Tesla-type pulse generator based on a mixed PFL is developed in this paper to produce intense electron beams and generate high-power microwaves (HPMs). The …

A Multifunctional Long-Lifetime High-Voltage Vacuum Insulator for HPM Generation

Liang Zhao, Jiancang Su, Rui Li, Xiudong Xu et autres

A multifunctional, long-lifetime, compact, and coaxial high-voltage (HV) vacuum insulator for Tesla-type generators is proposed for high-power microwave (HPM) generation. This vacuum insulator has two features. First, it is multifunctional since it can not only support the two conductors of the transmission …
