Abstract: A cyclotron for accelerating a beam of charged particles and extracting the beam. The cyclotron includes a vacuum chamber; a target support element sealed and coupled to the vacuum chamber and including a tubular channel leading to a target; first energy specific extraction kit including a first stripper assembly with a stripper located at a first stripping position for stripping charged particles at a first energy and a second energy specific extraction kit for driving modified charged particles of second energy along a second extraction path towards a target holder, wherein the energy specific extraction kit includes: a second stripper assembly with a stripper located at a second stripping position for stripping charged particles at a second energy and an insert for modifying an orientation of the tubular channel to match the second extraction path such that the modified charged particles of second energy intercept the target holder.

Abstract: The present invention is related to an apparatus for irradiating products conveyed on a pallet, comprising a beam source (3) for producing a radiation beam, a shielding wall (4) encompassing an irradiation chamber (2) and a revolving cylindrical door (6) having a recess (8) for holding said pallet, for bringing said pallet in and out of the irradiation chamber (2) wherein said high-energy radiation beam is directed towards a lateral side of said revolving door (6), for irradiating said pallet in said recess (8), or brought before said recess (8). The present invention is also related to a process wherein a product pallet is brought into an irradiation chamber (2) through a revolving cylindrical door (6) having a recess (8), and irradiated while in said recess (8) or in front of said recess (8).
