Summer Job for Students in Europe: NSF-sponsored International Research Experience for Students (IRES)
International US-European Joint Study of X-Ray Optics Thermomechanical Stability and Control

 

   Teams of US students will participate in a 3-year summer international joint research project involving European X-Ray Free Electron Laser facility in Hamburg (www.xfel.eu). Students will study thermomechanical stability and control of X-ray optics. Heating of X-ray optics is a major problem of the synchrotron, laser, and the in-house X-ray sources, which causes geometrical beam distortions, thus making beam conditioning quite a challenging task. The source beam energy is so high that it can melt the optics materials without proper cooling. Liquid nitrogen is currently used to cool diffraction-based (monochromator) optics in synchrotron sources. Thermomechanical modeling needs to be performed to design such systems with a lot of room for improvements and optimization. Only one degree Celsius monochromator surface temperature change significantly affects the diffracted beam wavelength, making it unusable. The research objective is to optimize and control X-ray optics (a challenging thermomechanical problem) through modeling and experimental efforts, which reflect the intellectual merit of the international research activities.

  

   The project started in 2010, and the second visit to Europe will begin in the middle of May 2011. Students will spend 3 months (May-August) at XFEL facility in Hamburg Germany and transportation to/from Germany along with $2,000/month living allowance will be covered by the grant.

   Student’s qualification requirements and application process: Engineering undergraduate or graduate students from US universities with hands-on knowledge of ANSYS FEM package; experience with X-ray diffraction and modeling thermomechanical problems is a big plus. Please email your resume and personal statement describing why you should be selected to volinsky@usf.edu. Minority students are strongly encouraged to apply.
