US Patent 11412606 Plasma generator and information processing method

It is an object of the present invention to provide a plasma generator capable of efficiently identifying the cause of an abnormal stoppage when an abnormal stoppage of the plasma generator occurs. When the controller determines that at least one detected value has become an abnormal value, the controller terminates plasma generation control. Further, in response to starting plasma generation control, the controller causes the storage section to store a history of detected values in association with time. As a result, it is possible to provide a history of detected values stored in the storage section to efficiently identify the cause of the abnormal stoppage.
