Claim Text:
1. A particle accelerator of the type synchrocyclotron for producing an energetic pulsed ion beam, said accelerator comprising an ion source for producing ions and a radio frequency acceleration system for accelerating said ions, said accelerator comprising: Means for varying the number of particles within each beam pulse of said pulsed ion beam from a minimum value to a maximum value as function of the value of a beam control parameter, said parameter being related to the operation of the ion source and/or of the RF system, A beam control device comprising: the particle accelerator further compromising: control means for automatically generating said calibration table or said mathematical function by defining a number of different values for said beam control parameter, producing for each said value a beam pulse and measuring the corresponding number of particles within each produced beam pulse.
