Target interaction lengths for cylindrical targets used in production of radioactive beams by high-energy protons

Cylindrical targets used for the production of radioactive beams by high-energy protons are analyzed in terms of target interaction length for some typical target systems. The analysis, using the Monte Carlo based LAHET code system, first determined applicable parameters of the beam/target interaction at 500 MeV incident proton energy. The analysis was then extended to other commonly-available proton energies up to 1000 MeV.
