Beam based alignment (BBA) techniques are important tools for precise beam orbit correction of a high power linac, and supplement to the model based or orbit response matrix (ORM) based correction methods. BBA will be applied to beam orbit analysis and correction of the FRIB linac arcs where a beam orbit offset within 0.1 mm is required to the second order achromatic beam tuning. In this paper, we first introduce the study of model based beam orbit correction of the arc, and then a more precise orbit correction with BBA. Realistic misalignment of beam elements and beam position monitors (BPMs) are included in the simulation studies.

Accelerator beam simulation is crucial for the successful commissioning and operation of the FRIB linear accelerator. A primary requirement of the FRIB linear accelerator is to support a broad range of particle species and change states. Beam simulations must be performed for these various accelerator configurations and it is important the results be managed to ensure consistency and reproducibility. The FRIB Lattice-Model Service has been developed to manage simulation data using a convenient web-based interface, as well as, a RESTful API to allow integration with other services. This service provides a central location to store and organize simulation data. Additional features include search, comparison and visualization. The system architecture, data model and key features are discussed.

The new software FLAME has been developed to serve as physics model used for on-line beam commissioning applications. FLAME is specially designed to cover FRIB modeling challenges to balance between speed and precision. Several on-line beam commissioning applications have been prototyped based on FLAME and tested on the physics application prototyping environment. In this paper, components of the physics application prototyping environment are firstly described. Then, the design strategy and result of the four major applications: baseline generator, cavity tuning, orbit correction, transverse matching, are discussed.

FRIB, which is a new heavy ion accelerator facility to provide intense beams of rare isotopes, is currently under construction at Michigan State University. Its driver linac accelerates all stable ions up to uranium, and targets to provides a CW beam with the energy of 200 MeV/u and the beam power of 400 kW. The beam commissioning of the its Front-End has been planned to start from Middle of 2016. The high level controls for incoming commissioning is under active development and deployment. The latest status progress will be presented in this paper.
