COSMIC-SLAC控制系统迁移挑战
COSMIC - The SLAC COntrol System MIgration Challenge
摘要：
目前的SLC控制系统是在20多年前设计和建造的。它所基于的许多技术已经过时并且难以维护。构成控制系统核心的VMS系统仍然很强大，但第三方应用程序几乎不存在，其长期前景令人怀疑。毫无疑问，SLAC需要一个能够支持可预见未来实验的控制系统。目前的B工厂或PEPII实验预计将运行至少10年。一个空前强度的自由电子激光器加上一系列正在进行的固定目标实验也在我们的未来。下一个线性对撞机或NLC也可能在我们的未来，虽然在时间上有点遥远。NLC的性能要求比我们迄今为止构建的任何东西都要高一个数量级。除了大量的IOC和过程变量外，物理学家还希望随时将所有内容存档。这使得NLC控制系统也有点像探测器系统。NLC控制系统还将需要当前SLC控制系统提供的丰富的加速器应用程序套件，以及更多现在在加速器物理学家眼中仅是一线之光的加速器应用程序。我们如何才能逐步从目前的SLC控制系统迁移到一个设计，将规模扩大到NLC，同时保持一切顺利进行中的实验？
英文摘要：
The current SLC control system was designed and constructed over 20 years ago. Many of the technologies on which it was based are obsolete and difficult to maintain. The VMS system that forms the core of the Control System is still robust but third party applications are almost non-existent and its long-term future is in doubt. The need for a Control System at SLAC that can support experiments for the foreseeable future is not in doubt. The present B-Factory or PEPII experiment is projected to run at least 10 years. An FEL laser of unprecedented intensity plus an ongoing series of fixed target experiments is also in our future. The Next Linear Collider or NLC may also be in our future although somewhat farther distant in time. The NLC has performance requirements an order of magnitude greater than anything we have built to date. In addition to large numbers of IOCs and process variables, Physicists would like to archive everything all the time. This makes the NLC Control System a bit like a detector system as well. The NLC Control System will also need the rich suite of accelerator applications that are available with the current SLC Control System plus many more that are now only a glimmer in the eyes of Accelerator Physicists. How can we migrate gradually away from the current SLC Control System towards a design that will scale to the NLC while keeping everything operating smoothly for the ongoing experiments?
