DESCRIPTION:Speakers: Elena Reznikova ()\nA new Transmission Hard X-ray In
 terferometer-Microscope (THXIM)\, which is based on X-ray refractive lense
 s and diffractive gratings\, was developed for 15-35 keV photon energies t
 o set up at the second front-end of VEPP-4M storage ring. The synchrotron 
 radiation (SR) path from the bending magnet source to the experimental hut
 ch is 17 m. The THXIM block sequence on the SR beam course within the 6.5 
 m hutch distance is the following: 1) The forvacuum block includes horizon
 tal and vertical slits\, a multilayered X-ray mirror monochromator\, an SR
  beam position detector and a blocker absorbing the direct beam. 2) The bl
 ock of the X-ray refractive condenser lens in the air atmosphere. 3) The b
 lock of a research object and the X-ray refractive objective lens with X-r
 ay diffractive gratings is in the air environment. 4) At the end of the be
 amline station\, the air block of the THXIM detector is disposed\, which i
 ncludes an X-ray scintillator (a 100 m thin\, 1 cm large area\, CdWO4 c
 rystal) and an optical microscope with a planapochromate objective\, incli
 ned mirror and a CCD camera. Between 2\, 3 and 4 blocks\, forvacuum tubes 
 for the beam inflights are disposed. We develop inclined X-ray lithography
  with SU-8 and PMMA resist\, as well as photo- and e-beam lithography and 
 galvanoplastics technologies of gold\, nickel and aluminum microstructures
  in order to create X-ray refractive lenses with high aspect ratios of 3D 
 apex elements and X-ray diffractive gratings with nanometer range periods.
  The X-ray refractive long compound paraboloid objective lenses with 100 
 m apertures and focal distances of several centimeters provide the THXI
 M resolution of dozens nanometers. The position choice for a THXIM researc
 h object within a local coherent zone\, which is obtained by means of an X
 -ray refractive condenser lens with a long-length focal waist\, is discuss
