Effective increase in beam emittance by phase-space expansion using asymmetric Bragg diffraction. | LitMetric

AI Article Synopsis

  • - We introduce a new method to enhance the use of phase space from synchrotron light sources for X-ray transmission microscopy! - This method employs specially shaped crystals to significantly expand the usable phase space, increasing it by more than a hundred times to improve compatibility with the microscope's objective lens! - Simulations using the SHADOW code validate our approach, and we analyze how optical aberrations affect nano-resolution X-ray imaging using techniques from matrix optics!

Article Abstract

We propose an innovative method to extend the utilization of the phase space downstream of a synchrotron light source for X-ray transmission microscopy. Based on the dynamical theory of X-ray diffraction, asymmetrically cut perfect crystals are applied to reshape the position-angle-wavelength space of the light source, by which the usable phase space of the source can be magnified by over one hundred times, thereby "phase-space-matching" the source with the objective lens of the microscope. The method's validity is confirmed using SHADOW code simulations, and aberration through an optical lens such as a Fresnel zone plate is examined via matrix optics for nano-resolution X-ray images.
