Description
In accordance with the discussion at SATIF15, we propose the same intercomparison problems of particle production from targets. Relatively large differences are observed for neutron and proton especially at small and large angles between Geant-4, PHITS, FLUKA-2021.2 and FLUKA 4-2.2. Results by using MARS and MCNP were desired to include in this intercomparison.
At SATIF16, we will present comparison between major Monte Carlo codes including MARS and MCNP concerning particle production with high energy protons.

Target materials and their sizes
Target geometry is the cylinder.
Source protons incident on the center of the cylinder bottom.
Target detector distance from the center of the cylinder is 500 cm.

(b) Cu : length 16 cm, diameter 1.6 cm and density 8.63 g/cm^3
(c) Au : length 10 cm, diameter 1.0 cm and density 19.3 g/cm^3 -
Quantities to be calculated
