Siberian Scientists Made Radiation Sensors for Large Hadron Collider
November 29, 2015 10:06


Scientists of the Tomsk State University (TSU) have designed sensors for measuring the radiation level in channels of the Large Hadron Collider (LHC) of the European Nuclear Research Council, the TSU professor Oleg Tolbanov reported to TASS.
"Preliminary tests the Large Hadron Collider are expected to be completed before the middle of December and the main tests will be carried out in January. We hope that the sensors will be put into operation. The fact that they are highly resistant to radiation was proved with tests back in 1997", - he said.
Professor Tolbanov noted that Tomsk sensors stand radiative exposure 100 times stronger than their analogs and can work for up to 10 years long. If the tests are a success the Tomsk State University will provide the European Nuclear Research Council with about 8 thousand sensors for the ATLAS experiment on searching superheavy elementary particles, in particular, the Higgs bosons.
Mr. Tolbanov explained that usually such devices are produced on the basis of silicon technologies, however, experience has proven that these devices cannot withstand work conditions on the Large Hadron Collider and deteriorate over a single experiment, which lasts for about 1,5 months.
"Background radiation is very high at low-angle deviations from the spot where two particle beams collide. Since the power of collisions in new experiments, radiation resistant sensors are required", - Professor emphasized.
The scientists of the Tomsk State University make sensors in their own pilot production with a unique technology that is not known to anybody else in the world. The devices offered to the European Nuclear Research Council were not developed for the Large Haldron Collider in particular: Tomsk scientists deliver them to the enterprises, which are engaged in production or operation of medical tomographs, heavy-duty microscopes and other hi-tech devices.
