Description
To explore the inner structure of fast moving objects, an X-ray flash generator in energy range from 30 to 200 keV is used. Since the X-ray radiation is scattered by the object, X-ray grids are used to collimate the beam of radiation near the X-ray tube and dampen the scattered radiation before detector. The development of microcollimators using LIGA based on synchrotron X-rays was performed.
Using anti-scatter, X-ray golden grids with a pitch size of about 40 microns will improve the signal-to-noise ratio, increase the spatial resolution, and reduce the undesired scattered radiation. LIGA technology, which combines deep X-ray lithography at VEPP-3 storage ring and electroforming, was used for manufacturing X-ray anti-scatter grids. The technique of fabrication of intermediate X-ray masks based on titanium membrane and working masks on glassy carbon membrane is described. The influence of LIGA rasters on the radiation spatial distribution for a pulsed X-ray apparatus experimentally researched.
The work was done using the infrastructure of the Shared-Use Center “Siberian Synchrotron and Terahertz Radiation Center (SSTRC)” based on VEPP-3 of BINP SB RAS (Novosibirsk, Russian Federation).
The anti-scattering rasters were created using the infrastructure of the Shared-Use Center "Siberian Synchrotron and Terahertz Radiation Center (SSTRC)" based on VEPP-3/VEPP-4M of BINP SB RAS
The work was supported by the Russian Science Foundation, project 14-50-00080.
