Masters topic:Development of a benchtop synchrotron
Coherent X-ray imaging brings benefit in imaging transparent samples such as thin biological samples. The nature of the short wavelength X-rays enhances high resolution imaging. These advantages have many applications in biomedical Particle Image Velocimetry (PIV). However, currently coherent X-rays are only available at a synchrotron, which increases the cost and the time for phase contrast imaging, making the technique less medically applicable.
According to Thomson scattering, the collision of the photons and relativistic electrons can generate coherent X-ray photons. This theory makes the generation of coherent X-rays in university laboratories possible. In practice, the number of X-ray photons required for phase contrast imaging has to be greater than 1010 photons per collision. A femtosecond laser would be a desirable light source to produce the required ultra-intensive light pulse.
With the recently installed femtosecond laser, and by focusing both the photon pulse and the electron beam into a spot with a few nanometer in diameter for high particle density collision, we propose to generate a coherent X-ray imaging facility.
Ivan was employed in the Division of Biological Engineering from September 2008 to December 2009 as a Physicist and Research Associate, where he worked on the following research interests: Diffraction physics; photon-electron interactions; optical systems for biomedical imaging; production of X-ray sources for table-top synchrotrons.
