The development of muon beams, which are needed for muon colliders and neutrino factories, is limited by the lack of user-friendly numerical simulation codes that accurately calculate scattering and energy loss in matter.  Geant4 – an internationally supported tracking toolkit developed to simulate particle interactions in large detectors for high energy physics experiments – has been partially adapted in a program called G4beamline to develop muon beam line designs.  This project will continue the development of G4beamline to enhance its graphical user-interface and add other features, in order to facilitate its use by a larger set of beam line and accelerator physicists.  In Phase I the graphical user interface of G4beamline was enhanced for greater effectiveness in beam line design, and the program environment was extended to Windows XP and Mac OS users.  The addition of space-charge effects and muon polarization to G4beamline were investigated.  Phase II will involve the investigation of more complex simulations, especially those that require iterative optimization of parameters, (e.g., space charge additions, polarization interactions, very low energy physics (< 100 eV)). 

 

Commercial Applications and Other Benefits as described by the awardee:  New discoveries and inventions in muon beam cooling over the last five years have greatly increased the probability that muon colliders and neutrino factories will be the discovery machines of the future.  A sophisticated tracking code would permit designers to accurately and realistically improve the performance of these machines.
