The EPICS channel archiver is a powerful tool to collect control system data of thousands of EPICS process variables with rates of many Hertz each to an archive for later retrieval. [1] Within the package of the channel archiver version 2 you get a Java application for graphical data retrieval and a command line tool for data extraction into different file formats. For the Paul Scherrer Institute we wanted a possibility to retrieve the archived data from a web interface. It was desired to have flexible retrieval functions and to allow to interchange data references by e-mail. This web interface has been implemented by the PSI controls group and has now been in operation for several years. This presentation will highlight the special features of this PSI web interface to the EPICS channel archiver.

Purpose and Benefit of Control System Training for Operators

The complexity of accelerators is ever increasing and today it is typical that a large number of feedback loops are implemented, based on sophisticated models which describe the underlying physics. Despite this increased complexity the machine operators must still effectively monitor and supervise the desired behaviour of the accelerator. This is not alone sufficient; additionally, the correct operation of the control system must also be verified. This is not always easy since the structure, design, and performance of the control system is usually not visualized and is often hidden to the operator. To better deal with this situation operators need some knowledge of the control system in order to react properly in the case of problems. In this paper we will present the approach of the Paul Scherrer Institute for operator control system training and discuss its benefits.

Control systems have become continuously more powerful over the past decades. The ability for high data throughput and sophisticated graphical interactions have opened a variety of new possibilities. But has it helped to provide intuitive, easy to use applications to simplify the operation of modern large scale accelerator facilities? We will discuss what makes an application useful to operation and what is necessary to make a tool easy to use. We will show that even the implementation of a small number of simple design rules for applications can help to ease the operation of a facility.
