Abstract
An adjustment support system using computer for start-up operation of cyclotron is being developed in order to support operators who, using their experiences and intuition, tune up dozens of components to maximite beam efficiency.
This paper describes a method of beam pattern diagnosis and adjustment guidance based on fuzzy relation as one function of the adjustment support system. The followings are the basic processes of this method.
(1) The computer extracts features of beam pattern which correspond with operators' criteria.
(2) The computer calculates causative possibility of each adjustment parameters by inverse operation of fuzzy relational equation, which formulates the relationship between criteria of beam pattern and adjustment parameters.
(3) The computer displays those causative probabilities in agraphical manner as a operation guidance. Not only the probabilities but also the criteria of beam pattern and their relationship are displayed in one figure.
(4) Operators select one adjustment parameter referring to the display and other informations such as history of adjustment, and they tune the parameter.
