Optimization of troubleshooting route in large accelerators

Abstract

One of the main functions of the large accelerator control system is automation of a troubleshooting process. Following from the assumption that the functional structure of the linear electron accelerator can be presented as a sequence of blocks linked among themselves into a prime oriented chain the comparison of two troubleshooting techniques has been performed. The first technique is a bisection method, which is simple in implementation but not optimum in general case. The second one is a more complex optimum iterative procedure. As a criterion of the method evaluation mean troubleshooting expenditures have been used. Sample results of the efficiency of the two methods for troubleshooting in 50-section linear electron accelerator (LEA) are presented.
