  • Patent number: 6498444
    Abstract: Systems and methods for tuning a charged particle accelerator (40) are described. An accelerator tuning system (44) includes a graphical user interface (110) that guides a tuning technician (42) through an accelerator tuning process and interfaces with a measurement instrument (46) configured to measure characteristic parameters of the accelerator (40). The graphical user interface (110) enables the technician (42) to make parameter measurements and interpret the results of those measurements more quickly and easily. A computer (50) may be programmed to generate the graphical user interface (110), and instructions (51) for generating the graphical user interface (110) may be carried on a computer-readable medium. An accelerator tuning method includes the steps of guiding a user through an accelerator tuning process and interfacing with a measurement instrument (46) configured to measure characteristic parameters of the accelerator (40).

  • Patent number: 6483263
    Abstract: A method and system for automatically conditioning a linear accelerator is disclosed. The method and system comprise the steps of measuring the global variables of the accelerator and evaluating a plurality of events based upon the measurement of the global variables in which the plurality of events have a hierarchy of importance. Finally, the method and system includes performing an action in response to the hierarchy of importance of the plurality of events. Accordingly, a system and method in accordance with the present invention allows an accelerator to be conditioned unattended. The system and method in accordance with the present invention combines software and hardware to measure global variables and modifies the condition of the accelerator based upon those variables. Through the use of a system and method in accordance with the present invention conditioning can proceed in small systematic steps, thereby resulting in better-conditioned accelerators.
