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).

Claims

1. A system for tuning an accelerator, comprising a computer programmed to generate a graphical user interface for guiding a user through an accelerator tuning process and interfacing with a measurement instrument configured to measure characteristic parameters of the accelerator.

2. The system of claim 1, wherein the graphical user interface is configured to display instructions for preparing the accelerator for a tuning parameter measurement by the measurement instrument.

3. The system of claim 2, wherein the graphical user interface is configured to display the measurement preparation instructions pictorially.
