RESUMO

The racetrack microtron under construction at the Instituto de Física da Universidade de São Paulo, is a recirculated electron accelerator that has a few hundred parameters to be monitored and controlled. These parameters belong to several subsystems like transport, vacuum, RF, and diagnostics. To decrease the cognitive burden of the operator and help him to control the machine a computerized control system was built, pervading all subsystems. This system allows the operator to measure and change the parameters of interest, or alerts him when some of these parameters exceed a pre-defined value. The system was built using the three-layer model methodology: input and output device layer; device server layer; and the user interface layer. In the input and output device layer, several instruments with different communication interfaces were used, either commercial or in-house built. In the device server layer industrial PCs were used. The user interface layer uses a conventional PC running a human-computer interface built with assistance of the LabWindows/CVI software (National Instruments). The control system must satisfy requirements of flexibility, up-gradability and cost, must stand during the accelerator lifetime and allow maintenance by the Labs technical support.
