The Budker Institute of Nuclear Physics SB RAS (BINP SB RAS) has created an experimental setup for studying the destruction of materials under the action of fast, repetitive thermal loads. This was reported in the press service of the university.
The studies will show the behavior of materials for creating the first wall of a thermonuclear tokamak reactor, under the influence of enormous temperatures (over 1000 degrees).
When creating a thermonuclear reactor, there is a problem in selecting materials for the first wall of the chamber, which holds the hot plasma. Plasma particle flows with a temperature of about 100 million degrees lead to thermal loads on the chamber lining. The new development will solve these issues in the shortest possible time.
The uniqueness of the installation lies in the fact that it can quickly reproduce the full cycle of loads that the wall will be subjected to during the entire expected service life of the reactor. It will allow accumulating up to 10 million heating pulses in about two working weeks. On other installations, this takes about a year.
An electron gun is integrated into the installation. It generates an intensive frequency-pulse beam. Then it hits the test target of the magnetic field. Cyclic heating of the test target occurs under the pressure of the beam.
Scientists managed to assemble and test the stand. The installation turned out to be more compact, powerful, and cheaper than its counterparts.
Earlier, www1.ru reported that specialists from MEPhI found an alloy to extend the service life of a future thermonuclear reactor.
