DESIGN OF PROTON-BEAM DEGRADER FOR HIGH-PURITY 89ZR PRODUCTION

This work investigated the most suitable type of degrader (Cu, Al or Nb) and its thickness, taking into consideration the salient aspects of concrete activation for high-purity 89Zr production by 89Y(p,n)89Zr nuclear reaction.The MCNP and FISPACT codes were used to determine the optimal degrader thickness and the radioactivity of shielding concrete
