Precision Cleaning of X-ray Mirror Surfaces for Synchrotron Optics Mirrors-surface contamination is a major challenge for all high-brightness and high coherent X-ray sources such the Advanced Photon Source and LCLS, and others. Under intense X-ray irradiation, hydrocarbons, particulates, and residual gases can form nanometer-scale carbonaceous films that degrade mirror performance. This eight-week project will investigate cleaning methods for precision X-ray mirror surfaces, including CO₂ cleaning, solvent cleaning, and peelable First Contact Polymer methods used in demanding optical systems such as LIGO and major telescopes. These approaches will be compared with established APS techniques such as solvents and DI-water, UV/ozone, oxygen plasma, and other low-damage cleaning methods, with emphasis on whether preparatory or repeated cleaning can prevent or control black, shellac-like carbon films. The student will conduct a literature review, prepare and test substrate samples, compare results with reference surfaces, work with APS experts in coatings, metrology, and optics cleaning, and prepare a final report and presentation summarizing results and recommendations.
