Technical advances of the TIMER project

摘要

We report on recent developments concerning the TIMER project that is based on the idea to extend the Transient Crating technique in the Extreme Ultraviolet region. We designed a setup only based on reflective optics, which permits to overcome the strong photon absorption in this spectral range. We also carried out some preliminary theoretical calculations in order to study the shape of the transient grating associated with the proposed setup.
