	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 FRIB driver linac will deliver heavy ion beams with beam energy above 200 MeV/u, and beam power on target up to 400 kW. Commissioning, tuning, and beam power ramping up of the world’s first SRF linac for high-power heavy-ion beams will be challenge, and developments of necessary physics application software tools are very important. In this paper, our major progress and the development plan of physics application software for the FRIB linac within Open XAL frameworks are discussed, which include the FRIB linac online model, MySQL database for physics applications, virtual accelerator application, and several other pilot physics applications. Deploying and initial testing of Open XAL and those pilot applications for FRIB are currently ongoing for a new cryomodule at Michigan State University.

The Facility for Rare Isotope Beams driver linac provides CW beams of all the stable ions (from protons to uranium) with a beam power of 400 kW and a minimum beam energy of 200 MeV/u in order to produce a wide variety of rare isotopes, mainly for nuclear physics study. The low beam emittances, both transverse and longitudinal, are key performance requirements, together with beam stability. These are required for efficiently separating one isotope from another, the reason for choosing this linac configuration. Multi-charge states (five charge states for the uranium case) are accelerated for maximizing the beam current, while keeping the low emittances. The efficient acceleration of high beam currents from 0.5 MeV/u through the superconducting linac is, needless to say, one of the biggest challenges. The beam power is more than 200 times higher than existing similar SC heavy ion linac. In particular, the SC cavities are difficult to protect from heavy ion beam damage, which can be 30 times larger locally than a proton beam with the same beam power. Other challenges peculiar to the FRIB linac will be presented, together with the solutions.
