English: Scientists of the functional electronics laboratory of TSU have developed a world-unique technology of the HR-GaAs:Cr semiconductor structures for ionizing radiation detection. Gallium arsenide sensors are made on wafers with a diameter up to 4 ".

Sensors are widely used in leading scientific centers: Joint Institute for Nuclear Research (JINR), European Synchrotron Radiation Facility (ESRF), Conseil Européen pour la Recherche Nucléaire (CERN), Deutsches Elektronen-Synchrotron (DESY), The Paul Scherrer Institute (PSI), Rutherford Appleton Laboratory Science and Technology Facilities (STFC RAL), Cornell University and a number of foreign spin-off companies.

Multi-element detectors can be used in all medical X-ray equipment and to create various non-destructive testing equipment with a very high (tens of microns) spatial resolution. They are also indispensable for performing the most complicated experiments in the field of physics, which are carried out in the world synchrotron centers. Detectors allow to get a clear image and they have high radiation resistance. TSU and DESY scientists have been developing a unique research instrument since 2018 – a Compton X-ray microscope for biological objects studying. The task of TSU scientists is to produce sensors based on gallium arsenide compensated with chromium (HR GaAs: Cr). These sensors will become one of the key elements of the microscope, as they will determine the sensitivity and the spatial resolution of the instrument. TSU became a member of the ATLAS international collaboration in 2015, and received a proposal to develop radiation-resistant detectors for future experiments.

TSU became a member of the FCAL international collaboration in 2019, and it will be able to contribute in the development of radiation-resistant detectors technology and sector-based matrix sensors for the international project on building a linear collider BeamCal International Linear Collide (ILC).
