电子加速器

In order to understand the proton therapy it is necessary to have a proton therapy equipment and system, which is more complicated than the conventional electron LINAC.

为了实现质子治疗，必须有一套比常规电子直线加速器更复杂，规模更大的质子治疗设备与系统。

This paper introduces the dust activation status at different positions in NSRL 200 MeV linac tunnel and gives some suggestions for radiation protection as well.

本文简要介绍中国科技大学国家同步辐射实验室200 MeV电子直线加速器隧道内不同地点灰尘的活化现状，并提出相应的防护建议。

Beijing Medical Equipment Institute is an independent institute for Research and Development of electron linac accelerators used for radiotherapy and reformed as a company recently.

The variable high-power directional coupler could be used in the high power RF systems for linacs and the other devices.

它具有调整范围宽，承受功率高，真空性能好的优点。可用于电子直线加速器和其它高功率微波设备中。

From magnifiers, optical microscopes, to radiation discovered at the beginning of the twentieth century, and with the advancement in accelerators, the observation of substances is becoming microscopic.

从放大镜、光学显微镜、电子显微镜，到二十世纪初发现了放射线，伴随著加速器的出现，对物质的观察已越来越微观，原子以下的世界逐步揭开。

Without the improvement in observation tools, many discoveries would be very difficult to verify. From magnifiers, optical microscopes, to radiation discovered at the beginning of the twentieth century

从放大镜、光学显微镜、电子显微镜，到二十世纪初发现了放射线，伴随著加速器的出现，对物质的观察已越来越微观，原子以下的世界逐步揭开。

It is so much easier to accelerator electrons than protons.

它是如此容易得多电子比质子加速器。

Today's accelerators can bring protons to much higher energies than they can electrons.

今天的质子加速器，可以带来更高的能量，以比他们可以电子。

Methods The calibrated LiF grain was enclosed with PVC tube and put into the esophagus near to targeted center, CT simulation and 3D-TPS design carried out and three-field radiation ,one anteriorly and two posteriorly, by 6-MV-X-ray of linear accelerator was done after confirmation by EPID.

标准电离室标刻LiF颗粒聚氯乙烯管封装，通过硅胶管置入食管腔近靶区中心，行CT模拟 3D TPS计划设计，电子射野影像系统确认后加速器 6 MV X线前一后二三野照射，TLD读数。

Mainly engaged in NBL series of linear electron accelerator research, development, manufacture and application.
