When even SPOs can no longer focus X-Rays, a Laue Lens still can.

Silicon Pore Optics technology can be used to realize high-efficiency Laue lens providing focusing power in the soft-gamma domain.
A Laue lens concentrates rays using Bragg diffraction in the volume of crystals (the Laue geometry). Silicon Laue lens Components (SiLCs) are similar to SPO stacks of Si plates that have been stacked to freeze their curvature, the main difference is that instead of using ribbed plates which creates pores and allows reflection, the light refracts in the bulk of the chrystal.
As a result of this method, SiLCs focus very high energy x-ray and gamma rays both in the radial and azimuthal directions, providing a concentration factor several orders of magnitude higher than that of Laue lenses made of mosaic crystals. SiLCs work in the hard X-rays or soft gamma-rays , i.e. from about 80 keV to about 500 keV.
Each SiLC will be a ring component, which can be integrated with other SiLCs into a large lens.
SiLCs have been developed in a collaboration with the University of California at Berkeley.

APPLICATIONS

  • Hard X-Ray / soft gamma ray telescopes – Highest possible performance and signal to noise at the highest possible energies for astrophysical measurement.
  • Synchrotron facilities focus high energy X-rays for experimentation
  • Radiation therapy – SiLC allows for extremely precise focusssing to improve radiation therapy targetting.
