Virtual Accelerator: Software for Modeling Beam Dynamics

The article discusses appropriate technologies for software implementation of the Virtual Accelerator. The Virtual Accelerator is considered as a set of services and tools enabling transparent execution of computational software for modeling beam dynamics in accelerators on distributed computing resources. The main purpose of a virtual accelerator is to conduct computational experiments to simulate the beam dynamics using various software packages with the ability to compare the results of calculations (in case solutions of the same problem are obtained by various means), and the ability to create a task flow (solutions of one package can be used as an input for the subsequent calculation in another package). Control system toolkits EPICS (Experimental Physics and Industrial Control System [9], realization of the Graphical User Interface(GUI) with the existing frameworks and visualization of the data are discussed in the paper. The presented research consists of a software analysis for realization of interaction between all levels of the Virtual Accelerator. We present the concepts and the design of the Virtual Accelerator, describe the prototype implementation and show early results.
