Fourth-generation storage rings (4GSRs) that exploit the multi-bend achromat lattice concept may be able to surpass the brightness and coherence that are attained using the present third-generation storage rings. This paper presents the characteristics of photon beams and an analysis of their coherence properties in Korea-4GSR to represent 4GSRs.
The process of "Glucose 11C" pharmaceutical production by means of a photonuclear reaction 12C(γ, n) 11C is considered. The parameters of bremsstrahlung and electron beam scattered in the converter are investigated and optimized. It is proposed to use a constant-field magnet to remove electrons from the photon beam. A magnet de-sign is proposed that allows obtaining a field of 0.5 T in a gap of 25 mm. The production of the 11C isotope in the glucose target was estimated.
