"Focussing and Diffraction using a High Harmonic Source"

Speaker: Ben Mills

Date: Wednesday 21 October 2009

Time: 2pm

Venue: B53 Seminar Room

Abstract:

High Harmonic Generation is a highly nonlinear process that can be used to generate a high flux, low divergence, coherent beam in the extreme ultraviolet (XUV) wavelength range. It is proposed that this radiation source could be implemented for microscopy using coherent diffractive imaging, with potential measurements including the shape characterisation of single proteins and other biological samples. This pre-viva talk will document the development of the diffraction beam line at the University of Southampton, and present experimental results on XUV optics, XUV coherent diffractive imaging and XUV diffraction from arrays of nanospheres.
