A compact 10 MeV S-band irradiation electron linear accelerator (linac) was developed to simulate electronic radiation in outer space and perform electron irradiation effect tests on spacecraft materials and devices. According to the requirements of space environment simulation, the electron beam energy can be adjusted in the range from 3.5 to 10 MeV, and the average current can be adjusted in the range from 0.1 to 1 mA. The linac should be capable of providing beam irradiation over a large area of 1 m2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\hbox {m}2}$$\end{document} with a uniformity greater than 90% and a scanning rate of 100 Hz. A novel method was applied to achieve such a high beam scanning rate by combining a kicker and a scanning magnet. Based on this requirement, a design for the 10 MeV linac is proposed with an RF power pulse repetition rate of 500 Hz; it includes a thermal cathode electron gun, a bunching-accelerating section, and a scanning transport line. The detailed physical design and dynamic simulation results of the proposed 10 MeV electron linac are presented in this paper.

Plate tectonics plays an essential role in the redistribution of life-essential volatile elements between Earth's interior and surface, whereby our planet has been well tuned to maintain enduring habitability over much of its history. Here we present an overview of deep carbon recycling in the regime of modern plate tectonics,with a special focus on convergent plate margins for assessing global carbon mass balance. The up-to-date flux compilation implies an approximate balance between deep carbon outflux and subduction carbon influx within uncertainty but remarkably limited return of carbon to convecting mantle. If correct, carbon would gradually accumulate in the lithosphere over time by（i） massive subsurface carbon storage occurring primarily in continental lithosphere from convergent margins to continental interior and（ii） persistent surface carbon sinks to seafloors sustained by high-flux deep CO2emissions to the atmosphere. Further assessment of global carbon mass balance requires updates on fluxes of subduction-driven carbon recycling paths and reduction in uncertainty of deep carbon outflux. From a global plate tectonics point of view, we particularly emphasize that continental reworking is an important mechanism for remobilizing geologically sequestered carbon in continental crust and sub-continental lithospheric mantle. In light of recent advances,future research is suggested to focus on a better understanding of the reservoirs, fluxes, mechanisms, and climatic effects of deep carbon recycling following an integrated methodology of observation, experiment,and numerical modeling, with the aim of decoding the self-regulating Earth system and its habitability from the deep carbon recycling perspective.
