Abstract

X-ray imaging technology is highly developed to meet the needs of high-energy physics and diagnostics of inertial confinement fusion. In this paper, we describe the design of a non coplanar toroïdal mirrors microscope. It consists of three off-axis revolution concave toroïdal mirrors working at grazing incidence. Non-periodic W/SiC multilayer coatings have been deposited on each mirror, in order to increase until 10 keV the bandpass of reflectivity of the microscope. These super mirrors have been designed to work at 0.6° grazing incidence angle and display a reflectivity better than 40% in the entire energy range 2-10 keV. Concerning the imaging performances, we have almost achieved 5 μm of spatial resolution in a field of 500 μm. Regarding to these results, this prototype of microscope, the so-called "Plasma Imageur X pour les Experiences Laser Mega Joule" (PIXEL), will be used for 2D spatial and 1D time resolved imaging of dense plasmas produced during inertial confinement fusion experiments at the future Laser Mega Joule French facility (LMJ).
