Description
We propose new inter-comparison problems of particle production from targets to find the reason of
relatively large differences between codes in neutron production as presented at SATIF-14.
In addition to neutron, proton, pion+, pion- and photon above 20 MeV are requested
to calculate in the revised problem.
At SATIF-15, we will present comparison between major Monte Carlo codes concerning
proton, pion+, pion- and photon production with high energy protons.

Incident particle
Pencil beam of protons with the following energy

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
(1) Neutron, proton, pion+, pion- and photon spectrum above 20 MeV in particles/MeV/sr/proton
at 0, 15, 30, 45, 60, 90, 120, 150 degrees with angular width plus/minus 0.5 degrees.
Photons from produced radionuclides are not necessary to include.
