	New computational tools are essential for accurate modeling and simulation of the next generation of muon-based accelerator experiments at the energy and intensity frontiers, such as a muon collider, a neutrino factory, stopping muon beams, or in general any application involving muons. There is a long list of crucial and not-yet-considered physics processes specific to muon accelerators that have not yet been implemented in any current simulation code. Implementing these processes will substantially enhance our confidence that the tools used in simulating and assessing the feasibility of a muon collider or a neutrino factory will accurately represent the performance of a real machine. We report here on the progress of developing advanced modeling tools to include such processes into the G4beamline code, one of the de-facto standard codes used for muon-based accelerator simulations.

MOPBA12	Mitigation of Numerical Noise for Space Charge Calculations in Tracking Codes	198
	L.G. Vorobiev, C.M. Ankenbrandt, T.J. Roberts Muons, Inc, Illinois, USA F. Schmidt CERN, Geneva, Switzerland
	Modern tracking codes have very high requirements to space charge calculations. They should combine the speed of calculations, to be able to track particles for very many turns (LHC accelerator chain, storage rings, etc), and a numerical accuracy and a physical symplecticity. Grid solvers and the modified Green's function algorithms were considered, compared, and the upgrades were suggested.

THPBA27	Simulation Workstation	1289
	T.J. Roberts Muons, Inc, Illinois, USA
	The Simulation Workstation is a software toolkit that provides a universal Graphical User Interface to most particle simulation codes. This includes: constructing and displaying the simulated system graphically, running multiple simulation codes from a single system description, displaying particle tracks or histories with the objects of the system, flexibly generating plots and histograms, and comparing the results from multiple simulations. The workstation itself knows very little about particle simulations – that knowledge is contained in the simulation codes themselves. As a consequence, the workstation can handle essentially any problem that any of the supported simulation codes can simulate. These include: beam optics calculations, ion source design,muon cooling channels, spacecraft radiation levels, nuclear reactors, complex shielding calculations, and accelerator driven subcritical reactors. The workstation offers interfaces to most CAD/CAE programs, enabling workflows that include multiphysics analysis by other programs. Initially the Simulation Workstation will support these simulation codes: G4beamline, MCNP6, and MAD-X; additional codes can be added by users.
