Moscow, July 6 – New nuclear clocks, which will be thousands or even tens of thousands of times more accurate than modern ones, may appear in Russia in 5-7 years, the general director of the All-Russian Research Institute of Physico-Technical and Radio Engineering Measurements (VNIIFTRI) from Rosstandart told the News Agency, where Participated in the development of such devices, Sergey Donchenko.
He showed that such potentially promising watches are capable of showing time with an accuracy of up to 21 decimal places, that is, 3-4 orders of magnitude (from a thousand to tens of thousands of times) more accurate than existing systems. However, according to the scientist, despite the fact that all theoretical calculations are already available, a method of physical implementation of a device with such accuracy has not yet been found.
Donchenko added that Russia makes the largest contribution among all countries in the world to the formation of the international time scale. The contribution of the Russian Federation, according to him, is about 20%.
In the field of making optical clocks, the institute is developing devices of the third generation. Due to changes in technology, the new watch will remove Doppler, temperature, and other physical shifts that affect accuracy. Thus, within two years, optical clocks with an accuracy of 18 or 19 decimal places may appear, Donchenko said.
