Specialists from the INP SB RAS have developed a domestic klystron, the most important part of linear electron and positron accelerators, which, in turn, are necessary for the creation of colliders and synchrotrons. Now in Russia it is possible to create linear accelerators of electrons and positrons exclusively on domestic technologies.
Linear accelerators of electrons and positrons are one of the most important parts of scientific installations that accelerate particles to almost the speed of light: colliders, synchrotrons, sources of Compton and terahertz radiation, and so on. To disperse the particles, a very large pulsed microwave power is required – about 50 MW (approximately the same amount is required for 50 thousand electric stoves switched on simultaneously). Therefore, the most important part of the accelerator is the klystron. It provides the necessary power by creating an accelerating field. “If the accelerator is a car, then the klystron is its engine,” comments Pavel Logachev, Director of the INP SB RAS, Academician of the Russian Academy of Sciences.
Without a klystron, it is impossible to create a particle accelerator, such as the SKIF Central Collective Use Center in Novosibirsk. Initially, the Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences planned to purchase klystrons from the Japanese company Canon, but the contract was terminated after the delivery of only one device out of four required. Therefore, Russian scientists have developed their own technology for creating these devices.
The power of the first klystron, created at the INP SB RAS, has already reached the design power of 50 MW. The device has been working reliably for two months now with parameters exceeding the requirements of SKIF, the institute began to manufacture the first serial devices.
The creation of a domestic technology for creating klystons will now make it possible to create high-energy linear accelerators of electrons and positrons using completely Russian technologies.
The domestic accelerator will be installed at the SKIF Central Collective Use Center, and it can also be used to create other installations. “In Russia, the technology may be in demand for the creation of projected sources of synchrotron radiation KISI-Kurchatov, RIF, SILA, for the electron-positron collider Super S-tau factory, the source of Compton radiation in Sarov, the neutron source in Dubna,” said the director of the INP SB RAS Academician of the Russian Academy of Sciences Pavel Logachev.
Alexey Paevsky, scientific director of the portal, visited the INP for the presentation of a new instrument. In the near future we will publish an interview with Evgeny Levichev, head of the SKIF Central Collective Use Center.
