OPERATING SYSTEM LINUX AS DEVELOPING AND RUNTIME PLATFORM FOR CONTROL SYSTEM OF PARTICLE ACCELERATOR

What operating system to choose is a common problem necessary to solve during development of control system for particle accelerator. It would be very attractive to use the same operating system as for development of software components of control system as for runtime both for real-time and non real-time applications. Remote boot-loading capabilities, mature software development tools, and other advantages of Linux make it very useful for development of software components of modern control system for particle accelerators. Our experience lets us to propose application of Linux operating system as for non real-time high levels as for real-time middle level of control system. Real-time extension of Linux- RTLinux is used for real-time applications. This choice allowed us to utilize effectively performance of x86 compatible computers, to have uniform hardware and software environment. Linux operating system have been used on different levels of control system of electron linacs as for gradual upgrading of the old control system as for development of new control system for newly designed compact accelerator. Software drivers for CAN-bus adapters together with DeviceNet library have been developed under Linux.
