UNIFIED ACCELERATOR MODELING USING THE Bmad SOFTWARE LIBRARY

The Bmad software library has proved to be a useful tool for accelerator simulations owing to its modular, objectoriented design. It is now used in a number of design, simulation, and control programs at Cornell’s Laboratory for Elementary-Particle Physics. Work is ongoing to expand Bmad in a number of directions. One aim is to have a complete framework in order to simulate Cornell’s Energy Recovery Linac from gun cathode (including spacecharge) to photon generation to photon tracking through to the x-ray experimental end stations. Other work includes synchrotron radiation tracking including reflections from the vacuum chamber walls, spin tracking, beam break-up instability, intra-beam scattering, etc. This paper will discuss the current state of the Bmad software along with the long-term goals.
