Next generation light sources and advanced accelerator facilities create ultrashort electron bunches with complex transverse distributions. They demand high-resolution beam profile information that is currently limited to approximately 50microns. Structures on the microscale are not resolvable, thus limiting the efficacy of diagnostics. A novel transverse diagnostic based on fiber optics will be developed to address the demands of advanced accelerator facilities. An array of fibers is drawn to intercept the beam and generate Cernekov radiation. The radiation is collected on a linear array detector and post-processed to yield transverse profile information with a resolution on the order of 10 microns. In Phase I numerical studies were performed on the physical concept of the device, including Monte Carlo simulations to determine cross talk effects. Most significantly, test fibers were irradiated to simulate real-life beam doses to determine the effective lifetime of the diagnostic. In Phase II, we will complete the engineering of the diagnostic. We will perform a proof of concept test to determine the effective lifetime, as well as full characterization and commissioning at an advanced accelerator. Commercial Applications and Other Benefits: Accelerators around the world use beam profile diagnostics that can be replaced by the proposed fiber mesh diagnostic. In addition, the remote tip/tilt bellows system for angular alignment may be an offshoot commercial product
