Benchmarking - code/code and code/experimental data
Calculational tools for radiation shielding at accelerators are faced
with new challenges from the present and next generations of particle
accelerators. All the details of particle production and transport
play a role when dealing with huge power facilities, therapeutic ion
beams, radioactive beams, and so on. Besides the traditional calculations
required for shielding, activation...

Same problems at SATIF9 were used for inter-comparison mainly to compare between AGS experiments provided by H. Nakashima with various codes. As the new item to be sent by participants, “particles treated to obtain the results” is added,
This paper presents a comparison of the neutron attenuation length of iron and concrete sent to the organizer by the end of April, including results...

Experimental studies of shielding and radiation effects at Fermi National Accelerator Laboratory (FNAL) have been carried out under collaboration between FNAL and Japan, aiming at benchmarking of simulation codes and study of irradiation effects for upgrade and design of new high-energy accelerator facilities. The purposes of this collaboration are (1) acquisition of shielding data in a proton...

Present study is a continuation of the project "Verification of Monte-Carlo transport codes" which is running at GSI as a part of activation studies of FAIR relevant materials. It includes two parts: verification of stopping modules of FLUKA, MARS and SHIELD-A (with ATIMA stopping module) and verification of their isotope production modules. The first part is based on the measurements of...

A shielding experiment using 243 and 387 MeV quasi-monoenergetic neutrons have been performed at the Research Center for Nuclear Physics (RCNP), Osaka University, Japan. Neutron energy spectra and doses behind concrete with 25, 50, 100, 200 and 300 cm thicknesses and iron with 10, 20, 40, 70, and 100 cm thicknesses have been measured. Two different sizes of NE213 liquid scintillators of 5" and...

RIKEN RIBF (Radioactive Isotope Beam Factory) is a big heavy-ion accelerator complex consists of a linac and five cyclotrons, of which last stage accelerator is a superconducting ring cyclotron (SRC). The maximum acceleration energy of it is 400 MeV/u for ions lighter than Ar and 350 MeV/u for heavier ions up to uranium. The accelerated beam is transported to BigRIPS (Big RIKEN...

Spallation models have to be benchmarked in order to use the best one according the reactions studied and/or to know their reliabilities. Developments of spallation models are linked to experimental results and this explains why fifteen years ago a first benchmark has been launched, restricted to particle production, followed by a second one on residues. Since then new data have been measured...

Radioactive fragments induced in an iron target bombarded by 400 MeV/nucleon carbon ion beam were measured and compared with simulation carried out using Monte-Carlo radiation transport code FLUKA.
An iron target thicker than the stopping range of carbon ion beam was irradiated with a focused 400MeV/u carbon ion beam. After the irradiation, the iron target was disassembled to extract...
