Dry run of SWISS summer school talks: (1) Plasma Homogenization for Overcoming Refractive Losses in X-ray Lasers (2) Critical aspects for a XUV microscope

Date Do, 06.09.2012 - Do, 06.09.2012
Time 14.15
Speaker Leili Masoudnia (1), Mabel Ruiz Lopez (2), Institute of Applied Physics, University of Bern
Location Universität Bern, Institut für Angewandte Physik, Gebäude exakte Wissenschaften, Hörsaal B116, Sidlerstrasse 5, 3012 Bern
Program (1) Refractive losses along laser-produced plasmas used as gain media are caused by density gradients. The pump pulse is thus deflected from the high gain region and the short wavelength signal steers-away causing loss of collimation. Hollow cylinders used as targets make the plasma homogeneous and can mitigate refractive losses by means of wave-guiding.
(2) The aim of this presentation is to evaluate the principle aspects in order to define the “XUV microscope”. We first review the basic components and the objectives and condensers architecture. Afterwards we discuss the critical parameters used to define the microscope: contrast, resolution, aberrations and costs. Then, we will give an overview of the different of microscope types. The last part of the speech will be dedicated to the studies realized in our group to build an XUV microscope.
