Controlling LEP/SPS accelerator equipment
The pilot project for a new design of the software of CERN`s LEP/SPS control system is described. The main deliverables produced during this project are: (1) an object-oriented design for generic access to LEP/SPS HEP (High-Energy Physics) equipment; and (2) an implementation/specialization of this design for one type of equipment, viz. Beam Loss Monitors. The design follows the OMT method. A generic object model is created which represents a possible accelerator-complex. This model is used (inherited) for the definition of the object model of a subsystem (BLMs) of the SPS/LEP accelerators. The dynamic behavior of the BLMs is modeled with state diagrams.
