Claim:
1. A particle beam therapy system comprising: an accelerator including a device controller controlling each of the acceleration-related devices and each of the extraction-related devices; a master clock generator generating a master clock pulse to determine a timing for starting the operation of the accelerator; a beam delivery line delivering the particle beam extracted from the accelerator; and a particle beam irradiation apparatus irradiating an irradiation target with the particle beam delivered through the beam delivery line, the particle beam irradiation apparatus including wherein the device controller checks that preparation for operating the acceleration-related devices is completed at a time point when receiving the master clock pulse, and commands the acceleration-related devices to operate in accordance with the operation pattern corresponding to the prescribed energy and then commands the acceleration-related devices to perform the extracting operation when an extraction enable signal indicating that the particle beam reaches the prescribed energy is turned ON and when an extraction-related device setting-status signal indicating that setting of the extraction-related devices completes for the prescribed energy is ON.
