Cyclotron includes an acceleration chamber, a vacuum system, an ion source system, and a control system that is configured to determine at least one operating parameter as a particle beam is directed along a beam path of the cyclotron. The control system is configured to decrease a supply of the charged particles for the particle beam based on the at least one operating parameter. The particle beam continues after decreasing the supply of the charged particles. The control system is also configured to increase the supply of the charged particles for the particle beam after a predetermined time period or in response to determining that an amount of gas molecules has reduced based on the at least one operating parameter.

Cyclotron and method for controlling the same

A particle accelerator including an electrical field system and a magnetic field system that are configured to direct a particle beam of charged particles along a designated path within an acceleration chamber. The particle accelerator also includes a foil holder having a beam window and a positioning slot that at least partially surrounds the beam window. The positioning slot is dimensioned to hold an extraction foil such that the extraction foil extends across the beam window and into the path of the charged particles. The positioning slot is defined by interior reference surfaces that face the extraction foil and retain the extraction foil within the positioning slot. The reference surfaces permit the extraction foil to move relative to the reference surfaces when the particle beam is incident on the extraction foil.
