加速器

The radiation plant that in recent years countrywide various places builds the foundation (cobaltic - 60 irradiation implement with electron beam accelerator) the amount rises a situation, and the radiation treatment application in main field, can say our country is preliminary already now formed a kind of brand-new radiate to machine an industry, aim to satisfy the demand that economic prosperity increases increasingly.

根据近年来全国各地区所建立的辐射装置(钴-60辐照器与电子束加速器)的数量增长情况，以及辐射加工在主要领域中的应用，现在可以说我国已初步形成了一种崭新的辐射加工产业，旨在满足经济繁荣日益增长的需求。

Methods The Siemens linear accelerator model of Primus M was used to produce electron, and the 6 dual fields technique which was primarily used by Stanford University School of Medicine was adopted to measure multifarious dosimetric characteristics.

在西门子直线加速器上，采用Stanford大学医学院建立的双机架多照射野方法，利用CMS公司的Dynascan三维水箱和PTW剂量仪及KODAK公司的XV2胶片等设备，分别测量各项剂量学特性的指标。

The principle of extrafocal radiation could be used for the calculation of monitor unit. An equation,, is derived to calculate the equivalent field size of a rectangular field, where k is the geometric weighting factor.

计算监控单位可利用非射源产生之辐射的原理，导出公式并接著加以计算，公式中K值为几何比重因子，Varian 21EX直线加速器为1.49。

In this thesis, we investi-gated some typical production processes related to chargino and neutralino viaelectron-positron, photon-photon and hadron-hadron collision at futural Linear Colliders and Large Hadron Colliders, and gave the analysis and discussion of both the radiative corrections and CP violating effects. To reach the required precision, we performed the calculation beyond the tree level. From the calculation we can conclude that the physical signals arising from charginos and neutralinos are considerable, both in direct production and indirect search process.

在本文中，我们研究了在未来的直线加速器和大型强子对撞机上通过电子正电子、光子光子和强子强子对撞与chargino，neutralino相关的一些典型过程，并给出了辐射修正和CP破坏效应的分析讨论，为了达到所要求的足够的精度，我们进行了树图阶以上的计算，通过计算我们可以得出结论，无论是直接产生还是间接寻找过程，来自chargino和neutralino的物理信号都将是显著的。
