53. Scaling models for radiation transport calculations at FRIB

Juan Carlos Zamora Cardona (NSCL)

4. Code status, advances, and model converters

Oral

The Facility for Rare Isotope Beams (FRIB) have recently started first operations. FRIB is designed to accelerate stable ions ranging from oxygen to uranium at energies above 200 MeV/u with a beam power on the production target up to 400 kW. The fast rare isotope beams produced via in-flight fragmentation (or fission) can be stopped, or stopped and then re-accelerated. Therefore, the...

12. Attenuation of neutrons in labyrinths: comparison of various calculation techniques

Dr Dali Georgobiani (FNAL)

5. Code benchmarking and intercomparison

Oral

To estimate attenuation of accelerator-produced neutrons in labyrinths and penetrations, we use a semi-analytical technique developed at Fermilab, as well as Monte Carlo radiation transport codes MARS, PHITS, and MCNP. The semi-analytical formalism suggests calculating the neutron attenuation factors for the labyrinth legs based merely on the source term at the entrance of the labyrinth; the...

13. Inter-comparison of Particle Production (4)

Hideo Hirayama (KEK, High Energfy Acceleraqtor Research Organization)

21/09/2022, 16:40

5. Code benchmarking and intercomparison

Oral

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...

52. The Shielding Integral Benchmark Archive Database (SINBAD) Task Force

Oliver Buss (OECD NEA)

21/09/2022, 17:00

5. Code benchmarking and intercomparison

Oral

The management of the Shielding Integral Benchmark Archive Database (SINBAD) is now maintained by a devoted Task Force under the auspice of the OECD NEA Expert Group on Physics of Reactor Systems (EGPRS). This new SINBAD Task Force (TF) was mandated in February 2021 and established in Q1 2022 to oversee the future development of SINBAD, which is consistent with the strategy of the Nuclear...

17. MCNP6 and PHITS benchmark calculations for proton accelerator shielding applications

Dr Yurdunaz Çelik (Belgium Nuclear Research Center (SCK CEN))

21/09/2022, 17:20

5. Code benchmarking and intercomparison

Oral

MCNP6 (Monte Carlo N-Particle) and PHITS (Particle and Heavy Ion Transport System) codes are widely used for many real-world shielding problems at accelerator facilities around the world. Nuclear interactions are described in these codes by both built-in physics models and tables with evaluated cross sections and secondary energy-angular distributions. Over the decades, many validation efforts...

34. Simulation studies of a pion production target for the Mu2e-II experiment

Stefan E. Mueller (Helmholtz-Zentrum Dresden-Rossendorf)

21/09/2022, 17:40

5. Code benchmarking and intercomparison

Oral

The Mu2e experiment, which is currently under construction at the Fermi National Accelerator Laboratory near Chicago, will search for the neutrinoless conversion of muons to electrons in the field of an aluminum nucleus with a sensitivity four orders of magnitude better than previous experiments. This process, which violates charged lepton flavor, is highly suppressed in the Standard Model and...
