A prototype of sensors based on sapphire, which are insensitive to radiation, was developed by scientists from Tomsk State University (TSU), the press service of the university reported on May 10.

It is noted that samples of multi-element sapphire sensors have no analogues in the world. The development was presented at the 25th international exhibition of electronics ExpoElectronica, held from 11 to 13 April in Moscow.

Sapphire-based sensors can be used to support Russian and international mega-science projects, writes TASS. These include the Siberian Ring Photon Source (SKIF), a 4+ generation synchrotron radiation source under construction in the Novosibirsk Region, NICA, a superconducting proton and heavy ion collider, which is being built on the basis of the High Energy Physics Laboratory (VBLHEP) of the Joint Institute for Nuclear Research (JINR). ) in outskirts of Moscow.

Tomsk scientists also plan to develop technological solutions for industry and medicine. According to Andrei Zarubin, a researcher at one of the laboratories at Advanced Technologies in Microelectronics, a chip testing system is needed to create an ionizing radiation detector. At ExpoElectronica, there were negotiations on joint research in this direction with other developers, he noted.

Russia is considered one of the largest producers of artificial sapphires, which are used in microelectronics. Synthetic sapphires are used as substrates in the production of microcircuits and non-ferrous metals. In addition, due to its crystal structure, sapphire is the main component of LEDs used in LED TV backlights.
