Description
The development of high resistivity gallium arsenide doped with chromium in Tomsk State University was inspired by the RD8
collaboration while seeking the radiation hard material for ATLAS pixel and strip detectors in 1992. Despite it was not
accepted in the final ATLAS design, GaAs:Cr with time became a promising material for X-ray imaging. The first hybrid pixel
detector based on GaAs:Cr sensor and a Medipix readout chip was made by the CERN-JINR-TSU collaboration a decade ago. Since
then the detectors like these were proven to be an excellent tool not only for tracking in particle physics, but also in the
applied fields like microtomography. The report shows a summary of results in computed microtomography using the GaAs:Cr
Medipix detector at JINR.
