Abstract
In order to allow easy estimation of the operating condition of a magnet by a technician of any skill level, and to allow accurate prediction of a potential failure beforehand, a data processing section is provided for resolving pressure data for a cooling helium gas, level (remaining amount) data for a liquid helium, first temperature data for a first stage of a refrigerator, second temperature data for a second stage of the refrigerator, and third temperature (room temperature) data for an equipment room in which a compressor is placed, as prespecified parameters, into a plurality of elements, using the elements as magnet data, calculating the Mahalanobis distance D of the normalized magnet data, and comparing the calculated Mahalanobis distance D with data stored in a database obtained by developing magnet data in a normal condition into a Mahalanobis reference space to estimate the operating condition.
