Existing simulation tools in accelerator control rooms are too simplified to handle the complex beam dynamics and the strong space charge effects, therefore providing no useful guidance for the high power beam tuning. We have been developing a GPU accelerated multi-particle beam dynamics simulator to try to bridge the gap. By combining the GPU technology and the multi-particle beam dynamics simulation algorithms, we have created a realistic beam simulator that is both accurate and fast enough to be useful in accelerator control rooms. Once connected to the EPICS control system, the simulator can rapidly respond to any control set point changes and predict beam properties along an ion linac in pseudo real time. Its applications include virtual diagnostics during operations, test-bed for new operation/control schemes, operation optimization and operator training.
