Abstract: A disturbance magnetic field region provided in an outer peripheral portion of a main magnetic field region of an accelerator has a peeler region in which a strength of a magnetic field decreases toward an outside, a regenerator region in which the strength of the magnetic field increases toward the outside, and a substantially flat region in which the strength of the magnetic field is larger than the strength of the magnetic field of the peeler region and smaller than the strength of the magnetic field of the regenerator region.

Abstract: A radionuclide production system and method that is capable of improving a radionuclide production amount and supplying a radionuclide with less excess and deficiency when the radionuclide is produced is required. Included is a particle beam irradiation apparatus that generates a particle beam, a plurality of targets that generate the radionuclide by irradiation with the particle beam, and a separation refinement apparatus that separates and refines the radionuclide from the targets. The plurality of targets are divided into an irradiation target group subjected to an irradiation treatment of generating the radionuclide by irradiation with the particle beam and a refinement target group subjected to a separation refinement treatment of separating and refining the radionuclide from the targets. The irradiation target group and refinement target group are processed in parallel.

Abstract: Disclosed is a serum albumin-thioredoxin fusion body which is improved in the activity thereof and is stable with respect to the activity. The serum albumin-thioredoxin fusion body is provided, which is characterized in that the thioredoxin is a modified from in which at least a cysteine residue located at position 73 from the N-terminal of an amino acid sequence for the thioredoxin or located at a position equivalent to the position 73 is substituted by another amino acid residue. the modified serum albumin-thioredoxin fusion body is superior in the activity and stability thereof, is reduced in immunogenicity and has superior safety compared with a fusion body in which the thioredoxin is non-modified form.

Abstract: A radionuclide production system is a system for producing a radionuclide by irradiating a liquid containing a raw material nuclide with bremsstrahlung radiation, the radionuclide production system including: a circulation path configured to allow a liquid containing a raw material nuclide to circulate; and a radiation generation unit configured to generate bremsstrahlung radiation to irradiate the liquid. A metal member containing a pure metal of a platinum group or an alloy of the platinum group is provided at an upper portion in the circulation path. In a radionuclide production method, the raw material nuclide contained in the liquid is transformed to the radionuclide by irradiating the liquid with the bremsstrahlung radiation while circulating the liquid containing the raw material nuclide in the circulation path, and oxygen and hydrogen generated due to radiolysis of the liquid are removed by a recombination reaction with a metal member formed of the pure metal.

Abstract: An accelerator includes: a main magnetic field magnet that has a plurality of magnetic poles and excites the main magnetic field in a space interposed between the magnetic poles; a magnetic channel that extracts the ion beam from an inside of the main magnetic field magnet toward an outside of the main magnetic field magnet; a displacement unit that displaces the ion beam circulating in a main magnetic field region to an outer side of the main magnetic field region; and a disturbance magnetic field region that is provided in an outer peripheral portion of the main magnetic field region and excites a magnetic field which disturbs the ion beam displaced to the outer side and guides the ion beam to the magnetic channel, the magnetic channel including a predetermined mechanism that suppresses a magnetic field gradient generated radially inward in the circulating ion beam region.
