SYSTEM FOR ADJUSTING THE ENERGY LEVEL OF A PROTON BEAM PROVIDED BY A CYCLOTRON, A CYCLOTRON TARGET HOLDER ASSEMBLY WITH A REMOVABLE DEGRADER, A REMOVABLE DEGRADER FOR USE IN A CYCLOTRON TARGET HOLDER ASSEMBLY, AND METHODS OF USE THEREOF
A system for adjusting the energy level of a proton beam provided by a cyclotron includes the cyclotron and a target holder assembly including a removable degrader. The removable degrader can be removed and/or replaced without removal of the target holder assembly from the cyclotron. A method for adjusting an energy level of a proton beam of a cyclotron includes providing a target holder assembly with a removable degrader in the path of the proton beam of the cyclotron to reduce the energy level of the proton beam, where the removable degrader can be removed from the path of the proton beam without removal of the target holder assembly from the cyclotron.
