A particle therapy system includes a particle accelerator for generating a charged particle beam, a beam delivery device, a beam transport system for transporting the beam from the particle accelerator to the beam delivery device, and a supporting device for supporting a subject. The beam delivery device is rotatable around the target and with respect to the supporting device, so as to be able to deliver the beam to the target according to a plurality of irradiation angles. The system also includes a controller configured to make the beam delivery device rotate at a beam-on speed and meanwhile to irradiate the target with the beam. The controller is configured to make the beam delivery device rotate at at least two different beam-on speeds with respect to the supporting device, a first speed corresponding to a first irradiation angle and a second speed corresponding to a second irradiation angle.

The invention is related to a method for monitoring a range of a particle beam in a target. The method is using gamma detectors for detecting prompt gammas produced in the target. The time differences between the time of detecting a gamma quantum and a time of emission of a particle or a bunch of particles from the radiation device are determined. A statistical distribution of those time difference is used to deduce information related to the range of the beam. The invention is also related to an apparatus for monitoring a range based on measured time profiles of detected prompt gammas.
