Intercomparison of Particle production

Speaker

Hideo Hirayama (KEK, High Energy Accelerator Research Organization)

Description

Intercomparison of Particle production Hideo Hirayama asn Toshiya Sanami KEK, High Energy Accelerator Research Organization 1-1, Oho, Tsukuba, Ibaraki, 305-0801 Japan In accordance with the discussion at SATIF11, we sent the following inter comparison problemswe of particle production from thick targets to understand the differences of neutron attenuation inside Fe and concrete. 1. Incident particle Pencil beam of protons with following energy (a) 1 GeV (b) 10 GeV (c) 100 GeV 2. Target materials and their size Targets geometry is the cylinder. Source protons incident on the center of the cylinder bottom. Target detector distance from the center of the cylinder is 500cm. (a) Al : length 40cm, diameter 4.0cm and density 2.7g/cm^3 (b) Cu : length 16cm, diameter 1.6cm and density 8.63 g/cm^3 (c) Au : length 10cm, diameter 1.0cm and density 19.3 g/cm^3 3. Quantities to be calculated Neutron spectrum above 20 MeV in n/MeV/sr/proton at 15, 30, 45, 60 ,90,120,150 degrees with angular width ±0.5 degrees. 4. Calculated results must be sent to H. Hirayama at KEK (hideo.hirayama@kek.jp) with the following data till March 30 of 2014 to prepare the intercomparison. (a) Name of participants and organization (b) Name of computer code used for calculations (c) Name of data base used in the calculation At SATIF12, we will present compariosn between results sent us till the end of March.

Summary

Present compariosn of neutron production by high energy protons between various codes will be presented to understand the differences of neutron attenuation inside Fe and concrete.
