Nuclear Analysis of High-Power LIEBE Molten Target at CERN for the Production of Radioisotopes

To enhance the production of short-lived isotopes, higher beam powers are sought, which require targets able to accommodate them. One such target prototype is a liquid metal LIEBE, developed at CERN. In this paper, simulation proton interaction with LIEBE presented. Simulations were performed by series transport calculations using MCNP Monte Carlo code. The latest input was created in high-fidelity geometry, and FENDL-3.1 cross-section data library used. Flux dose rate maps obtained from simulations presented paper. maximum around roughly 361 Sv/h for gamma rays 214 neutrons. 70 MeV–100 µA penetrates 7 mm deep into eutectic lead–bismuth. Based on this, further required changes can be evaluated.
