Fig. 1: Experimental setup for acquisition using X-ray ptychography.

a A diagram illustrating the experimental setup of the ptychography end-station at I13-1 (CS = central stop, FZP = Fresnel zone plate, OSA = order sorting aperture). Also shown is b the sample MTL-G, a 10 μm sized cube extracted from silicate glass within a clast of the MTL eruption using FIB, mounted on a tungsten needle. c 3D rendering of silicate glass sample MTL-G, produced from the data acquired using X-ray ptychography. The volume rendering was produced using VGStudio.
