  1. Other MCs and data used for verification & validation J. Apostolakis 19 July 2006

  2. Other transport ‘codes’ • Other ‘all-particle’ Monte Carlo: • MCNPX (related to MCNP 4.x, 5.x) • FLUKA • MARS • SHIELD • PHITS • And other well known hadronic codes • MCNP • LAHET • Several papers in past 4-6 years on their extension, improvement of their modeling

  3. Cascades INCL (Liege) CEM (M/H) Peanut (F) Precompound & below GEM, Furihata Generalised Evaporation Model ABLA GEMINI High-energy / string DPM LAQGSM Dubna QGSM ‘Models’ / Event Generators

  4. Other comparisons for cascades • How well does a cascade disintegrate a target nucleus? • Difficult to measure slow moving ions • Except if you give them momentum

  5. Residual nuclei (reverse kinematics) • GSI • Projectile nucleus with ~ 1GeV/A on hydrogen target • Many results: • 1 A GeV 208Pb + p • T. Enquist et al Nuc. Phys. A 686 (2001) 481 • And on d target Nucl. Phys. A 703 (2002) 435

  6. T. Enqvist et al. / Nuclear Physics A 703 (2002) 435–465 Data from reaction 208Pb(1AGeV) + d

  7. GSI data: proton on Gold This figure: arXiv:nucl-th/0404018 Data: F. Rejmund et al., Nucl. Phys. A 683, 540–565 (2001); J. Benlliure et al., Nucl. Phys. A 683, 513–539 (2001) compared with CEM2k + GEM 2

  8. This figure: arXiv:nucl-th/0404018 Data: F. Rejmund et al., Nucl. Phys. A 683, 540–565 (2001); J. Benlliure et al., Nucl. Phys. A 683, 513–539 (2001) • compared with • LAQGSM+GEM2 • INCL + ABLA

  9. Data for 15 – 65 GeV With the application of proton radiography in mind, LANL/FNAL collated existing data with 30-70 GeV projectiles for benchmarking: • SG Mashnik, R. E. Prael, A. J. Sierk, K. K. Gudima, and N. V. Mokhov, “Event Generator Benchmarking for Proton Radiography Applications”, nucl-th/0303041 • URL http://arxiv.org/abs/nucl-th/0303041 ) • Proton radiography • See eg http://www.bnl.gov/est/ra.asp

  10. Some data for 15 – 65 GeV • “Production of Tritons, Deuterons, Nucleons, and Mesons by 30-GeV Protons on Al, Be, and Fe Targets,” • A. Schwarzschild and C. Zupancic, Phys. Rev. 129 (1962) 854 • “Particle Production at Large Angles by 30- and 33-BeV Protons Incident on Aluminum and Beryllium,” • VL Fitch, SL Meyer, and PA Piroue, Phys. Rev. 126 (1962) 1849 • “Charged Pion Backward Production in 15–65 GeV Proton-Nucleus Collisions” • OP Gavrishchuk et al., Nucl. Phys. A523 (1991) 589 • the Be data are available from HEPDATA: REACTION DATA These are just a few of the references ...

  11. Pi- productionp A @44 GeV • OP Gavrishchuk et al., • Nucl. Phys. A523 (1991) 589

  12. 30 GeV p on Be • Comparison plot from SG Mashnik et al nucl-th/0303041 • Data: A. Schwarzschild and C. Zupancic, “Production of Tritons, Deuterons, Nucleons, and Mesons by 30-GeV Protons on Al, Be, and Fe Targets,” Phys. Rev. 129 (1962) 854

  14. More references • Merging the CEM2K and LAQGSM Codes with GEM2 to Describe Fission and Light-fragment Production • http://arxiv.org/abs/nucl-th/0304012 • More on GSI reverse kinematic measurements • http://www-w2k.gsi.de/charms/theses.htm

  15. Summary • Need to be aware of other codes • Emerging application areas • Developments in modeling • New or established data compared • The data used to benchmark are potentially valuable also for our verification and validation • Example of 30-70 GeV data • GSI reverse kinematic 1 GeV/A nucleus on H
