Also, ROOT usage in data-analysis demonstrated Bertini Cascade: Aatos Heikkinen Install/improve Coulumb barrier in Bertini cascade: Aatos Heikkinen Release sub-model interfaces (evaporation, precompound) Optimize code for speed Tune internal cross-sections and nuclear model Bertini Cascade: Extend pion cross sections to include more pions, kaons in final state: Dennis Wright Continued hadronic validation at medium energy: Dennis Wright includes literature search and compilation of new data New models: Begin development of new parameterized model using HARP data: Vladimir Ivanchenko with Dennis Wright Heavy Ions ---------- Validation of binary cascade for heavy ion-ion collisions: Tatsumi Koi Extend binary cascade or develop new model to handle high Z and high energy JQMD: Tatsumi Koi Implementation of additional nucleus-nucleus physics or interfaces with nucleus-nucleus models: Pete Truscott Neutrons -------- Neutron validation: Alex Howard Look into n-Tof and MEGAPIE/Isolde as possible benchmarks Begin migration from G4NDL to Livermore neutron data library format: Tatsumi Koi this includes developing a new high precision neutron category of models to eventually replace the existing HP models Elastic scattering ------------------ Validation and tuning of elastic models: Vladimir Ivanchenko with Dennis Wright Deliver first version of charge exchange process: Vladimir Ivanchenko Coherent elastic hadron scattering from nuclei: Nikolai Starkov optimize calculation of elastic scattering distibution function (large increase in speed expected). take into account difference between hadron-proton and hadron-neutron parameters of elastic scattering amplitude prepare a generator of quasi-elastic hadron-nucleus scattering summed over all discrete and continuous parts of the spectra Cross Sections -------------- Complete Glauber-Gribov cross sections: Vladimir Grichine Test Barashenkov (p,n) cross sections: Vladimir Grichine CHIPS parameterization: Mikhail Kosov Subtract the CHIPS elastic XS from the total XS measurements and use them together with the inelastic XS measurements for CHIPS parameterization of inelastic XS for nucleons Use the CHIPS parameterization of electromagnetic pA elastic scattering for a discrete process, which can substitute for multiple scattering (continuous) process of protons Use NN and NA elastic XS approximation for simulation of incoherent quasi-elastic and coherent charge exchange reaction of nucleons on nuclei Tests and Examples ------------------ Make new advanced example of a sampling calorimeter (HADR02): Vladimir Ivanchenko Improve tests: Vladimir Ivanchenko test30 and test35 CHIPS: Mikhail Kossov --------------------- Tuning low energy nucleon-nucleus CHIPS inelastic interaction: Collect data base of differential multiplicities for the tuning of pA inelastic interactions, make a test facility (test49) for validation and tuning of Geant4 inelastic processes Find an optimal combination of deep inelastic CHIPS nuclear fragmentation and quasi-elastic (a number of effective quasi-free nucleons) At medium and high energies generalize quasi-elastic interaction (with fixed number of effective nucleons) to quasi-free NN interaction (multiple meson production on quasi-free nucleons). Develop low energy simulation of antiproton-nuclear interactions Parameterize elastic and inelastic cross-sectoions Tune the CHIPS inelastic antiproton-nuclear interactions for low energies Upgrade photo- and lepto-nuclear single nucleon production Tune (gamma,n) branching of photo-nuclear reaction; Convert (n,gamma) cross-sections to (gamma,n) cross-sections Add quasi-elastic (l,l' N) lepto-nuclear reactions As soon as the low energy CHIPS program is done for nucleons (and anti-nucleons), make first steps for CHIPS pion-nuclear.
