Description

In recent years, the Japan Proton Accelerator Research Complex (J-PARC) has completed the design report for a Proton Beam Irradiation Facility (PBIF). This facility will be used for material irradiation, the manufacturing of medical radioactive isotopes, testing semiconductor soft errors, and providing proton beams for space applications, utilizing the H- beam generated by the J-PARC linac. The PBIF beamline will be in an existing tunnel within the J-PARC linac. It will extract the H- beam from the J-PARC's linac using a pulse magnet and septum arrangement and transport the beam through achromatic lattices. One of the main challenges for the PBIF beam line is to efficiently transport the beam from the main line of the J-PARC linac to the testing area, while ensuring that the design fits within the existing tunnel and does not interfere with the components already installed in the J-PARC linac. This work provides a report and discussion on the optical design of the PBIF beamline.
