SLS光束线数据采集与控制系统
The SLS Beamlines Data Acquisition and Control System
摘要：
12月15日，瑞士光源（SLS）首次产生了存储光束。这一重要里程碑是在非常紧迫的时间表内实现的。所有主要系统都由Epics控制的事实使这一挑战变得可行。在第一阶段，有四条光束线：两条用于表面科学界，一条用于粉末和表面衍射以及计算机微断层扫描，最后一条用于蛋白质晶体学。所有这些都配备了插入设备，用户希望将其视为像单色仪或实验站一样的有源子系统。光束线控制系统基于与机器相同的硬件和软件技术。这意味着广泛使用运行Linux RedHat 6.2和VME系统（PowerPC）的个人计算机。这种选择的优点是将插入设备直接实施到光束线和实验框架中。尽管实验应用程序接口因光束线而异，但用于连接所有子系统的标准软件技术基于Epics工具包和Cdev。该工具包提供的诊断工具在光束线调试过程中得到广泛使用。最后，我们帐户的一些例子，集成专用的第三方和商业非Epics的实验控制软件产品到光束线控制系统。这个领域的关键元素是CORBA、Python和Portable Channel Access Server。
英文摘要：
On December 15th the Swiss Light Source (SLS) produced a stored beam for the first time. This important milestone was achieved in a very tight time schedule. The fact that all major systems are controlled by Epics made this challenge feasible. In the first phase there are four beamlines: two for the surface science community, one for powder and surface diffraction and computed micro-tomography, and the last one for protein crystallography. All of them are equipped with insertion devices, which users want to treat as active sub-systems like a monochromator or experimental station. The beamline control systems are based on the same hardware and software technology as is the machine. This implies extensive use of Personal Computers running Linux RedHat 6.2 and VME systems (PowerPC). The advantage of this choice is a staightforward implementation of the insertion devices into the beamline and experiment framework. Although the experiment Application Program Interfaces differ from beamline to beamline, the standard software technology for linking all sub-systems is based on the Epics toolkit and Cdev. The diagnostic tools provided by this toolkit are being extensively used during the beamline commissioning. Finallly we account on some examples of integrating dedicated 3rd party and commercial non Epics software products for experiment control into the beamline control system. Key elements in this domain are CORBA, Python and Portable Channel Access Server.
