The X-ray beam is generated by an X-ray tube with Ag target (Amptek Mini-X X-ray tube) (see Supplementary Fig. 7a for X-ray energy spectrum). The device was located at the axis of the X-ray beam with a distance ~20 cm where the X-ray dose rate in air was carefully calibrat...

1a. The synchrotron X-ray beam is directed toward the PNSs floating on the water surface of an LB trough at the grazing angle αi = 0.367° (Supplementary Fig. 1). The wavelength of the incident X-ray is 1.239 Å. The charge-coupled device (CCD) detector, placed ...
“hard” X-rays. Finally, we show that the device can reliably operate in relevant environment, as assessed with a high-energy X-ray beam produced by a medical LINAC (linear accelerator) commonly used for radiation therapy to treat cancer, further demonstrating the high potentiality of ...
In analyzer-based imaging (ABI) or diffraction enhanced imaging (DEI), the X-ray beam is refracted by a crystal, which is rotated for maximum intensity forming a so-called rocking curve. A sample in the beam changes this curve, which is related to the differential phase contrast signal of...
beam path during this measurement. A Fe foil upstream of the transmissive spectrometer was used to calibrate the absolute energy axis of the spectrometers. The response function of the transmissive spectrometer was established by recording at a fixed spectrometer setting the average SASE spectra at ...
Three Cu filters, 0.5, 1.0, and 2.0 cm thick, were used to harden the X-ray beam. Beam hardening was approximately corrected by the operating software with a correction table calculated using the correct metal material. Image processing In our study, CT images were processed using Python ...
Si wafer as a solid support was used for the fine alignment of the samples to the X-ray beam, as confirmed by a mirror image of a wetting ridge (Fig. 2a) below the critical angle (0.22°) of Si. X-ray imaging The experiment was conducted using TXM (Fig. 1a)37,38 at the 32-...
