  3. The French and Korean LIA teams

  4. Members • Korea Group • Kihyeon Cho (KISTI) • Kyungho Kim, Youngjoon Kwon (Yonsei U.) • Huiyoung Ryu, Taegil Bae, Junghyun Kim, Soo-hyeon Nam(KISTI) • France Group • Marc Verderi (LLR, IN2P3)

  5. For particle Physics Theory-Experiment-Simulation Theory B Physics • Phenomenological Model • - Lattice QCD Experiment Beam Simulation • Cyber HEP Lab • Geant4 -KISTI Supercomputer • - CDF • Belle • BaBar  To probe the Standard Model

  6. Geant4 Simulation To find Higgs particle Geant4 Theory-Experiment-Simulation

  7. The purpose (1/2) • To collaborate on beam simulation based on Geant4 • The Korean and French teams have indeed developed Geant4 R&D working within Geant4 collaborations. • The Koran team for their implication in the RISP (Rare Isotope Science Project). • KISTI team has been working on Geant4 R&D (AIX, MT) and also Geant4 beam simulations for secondary beam. • The French team has been working on beam simulations for particle physics accelerators (ATF2) and is moving to medical applications.

  8. The purpose (2/2) • We have also fundamental topics in High Energy Physics namely the B physics. • B Physics is a major topic where the French IN2P3 team is pursuing its participation especially in BaBar experiment while Korean team in CDF and Belle/BelleII experiments. • We have searched for rare decay mode to probe Standard Model and search for new physics, while the French team has continuing interest in CP violation. • Therefore, we have still important breakthroughs are expected in these coming years for B physics theories.

  9. Geant4 Collaboration

  10. KISTI colleagues have already made a big contribution in testing of recently released prototype of multi-threaded Geant4, and in enhancing our support on AIX operating system. We find KISTI is rapidly becoming one of the two major development and user-support centers in Asia, complementing with KEK in Japan Geant4 Spokesperson - Makoto Asai (SLAC)

  11. Geant4 @ KISTI Supercomputer

  12. KISTI Supercomputing Porting • Sun Linux Cluster • Geant4 ST • Geant4 MPI(ParGeant4) • Geant4 MT • IBM AIX OS • Geant4-MT • Medical Application

  20. Proton

  21. Plan of Heavy Ion Beam Simulation • To study secondary beam using proton beam at 238U target • To study interactions between 238U and 12C, … • French Group will benefit it.

  22. B physics in Korea H.Y. Ryu work in progress T. Bae, et al. PRL 109, 041601 (2012) C.-H. Chen, S.-h. Nam, PLB 666, 462 (2008) J. H. Kim et al. PRD 86, 031101(R) (2012) K. Cho, S.-h Nam, [hep-ph] 1112.0091 Y. J. Kim, K. Cho et al. CDF (2012) S.-h Nam et al. PLB 691, 238 (2010) K. Y. Lee, S.-h Nam, PRD 85, 035001 (2012)

  23. French Group Activity

  24. French group activity (1/2) • French group involved in development for medical beam instrumentation. • In the context of the “GDR MI2B” • Development of beam profilers (hodoscopes made of plastic fibers + camera) used in CNAO (Pavie, Italy) and MedAustron (Wiener Neustadt, Austria). • Start investigation of beam profilers based on OTR or secondary emission • For better tolerance to radiations Hodoscope developed by M. Haguenauer & Co., now retired. CCD camera Fiber plane (other direction plane on the other side)

  25. French group activity (2/2) • Has interest in simulating beam-line + instrument. • Korean group developed such Geant4 ion beam line simulation that French people should benefit from • Background from beam line and near environment to be simulated likely with event biasing methods • French group is developer of these techniques in Geant4 (with new ones for next G4 release), and could help in making these methods used by Korean team. • Has experience of neutron background simulation at ATF2 using such class of techniques. • Such methods are generic and could be applied elsewhere, in treatment planning for example. Ex. of data/MC+biasing comparison of plastic scintillator waveform from neutrons from beam dump @ATF2 Data Sim. (other sim.) time (ns) Test plot for new biasing methods in Geant4: interaction of g are forced in a thin liquid-N2 volume. Usual sim. Biased sim. z (mm)
