Porting of Epics to Real Time Unix, and Usage Ported Epics for Fel Automation

This article describes concepts and mechanisms used in porting of EPICS (Experimental Physical and Industrial Control System) codes to platform of operating system UNIX. Without destruction of EPICS architecture, new features of EPICS provides the support for real time operating system LynxOS/x86 and equipment produced by INP (Budker Institute of Nuclear Physics). Application of ported EPICS reduces the cost of software and hardware is used for automation of FEL (Free Electron Laser) complex. PORTING OF EPICS TO REAL TIME UNIX The aim of the porting [1] was the reduction of cost of hardware and software required for creation of distributed control system which is built on base of personal computers with processors Intel x86, which has best relation of the cost per performance. INP has the rich experience of development of the special equipment for the particle accelerators, which is used for creation of FEL [2], and CAMAC devices made in INP is applied for automation of FEL. LynxOS/x86 [3] was chosen as low-cost UNIX real time operating system that supports POSIX standards. Besides, free software of GNU and XFree86 projects works at
