Ultra-bright and ultra-short X-rays

Sala 1.4.14, Ciências ULisboa

Por Marta Fajardo (IPFN, Instituto Superior Técnico).

The X-ray and EUV sources that were awarded this year's Nobel Physics Prize are the shortest light sources ever produced. Although they don't have much energy, thanks to their duration, which can be up to attoseconds (1E-18 s), they are extremely bright. In this seminar we will visit the world of X-rays created by lasers, with a detour to the VOXEL laboratory at the Instituto Superior Técnico, where we are developing and manipulating these new light sources.

Short bio: Marta Fajardo is an Associate Professor at Instituto Superior Técnico and carries out her research at the Institute of Plasmas and Nuclear Fusion. With a PhD from Ecole Polytechnique and Instituto Superior Técnico in 2001, she began her career studying plasmas for controlled nuclear fusion. On her return to Portugal, she carried out research into secondary sources of radiation such as X-ray lasers and high harmonics, and was Principal Investigator in several experimental laser campaigns in Europe and the United States. She currently leads the VOXEL station, which operates a Ti:Sa 35 fs kHz laser and 7 mJ per pulse, and is equipped with an EUV radiation generation beamline and interaction chamber for high-intensity lasers, which her team uses to study new X-ray sources and their applications to high-resolution imaging and dense plasma diagnostics. Internationally, she currently coordinates the EIC-Pathfinder NanoXCan project, which aims to optimize high repetition rate sources using machine learning and develop a new X-ray microscope, and is the Vice-Chair of the ERIC Extreme Light Infrastructure Advisory Committee.
