1. 14/06/2007Hayg GULER (LLR)1 ATF2 line studies with BDSIM using two different beam inputs parameters

2. 14/06/2007Hayg GULER (LLR)2 BDSIM Choice particle type (e-,e+, gamma) Choice energy, input parameters Sampler : “record” positions (after the selected element). Create one TTree each time (  possibilities to see a Z dependence for example) BDSIM Options: option,physicsList hadronic_standard em_muon em_standard Options, beam characteristics (beam pipe radius )

4. 14/06/2007Hayg GULER (LLR)4 Energy loss No Energy loss No creation of secondary particles too perfect (?) Other option to switch on ?

5. 14/06/2007Hayg GULER (LLR)5 Beam parameters (x) One distribution after each element No secondary particles (… !)
