Specialists from the Budker Institute of Nuclear Physics SB RAS (BINP SB RAS), together with the companies "Optikon" (Novosibirsk) and "Polema" (Tula), have manufactured 800 getter pumps to create ultra-high vacuum in the storage ring of the SKIF synchrotron being built. The equipment was developed in Russia and will replace imported analogues.
The new pumps, made of titanium, zirconium, and vanadium alloys, will be evenly distributed throughout the 477-meter accelerator ring to maintain the required vacuum level. Work on their development began in 2020 due to the high cost of foreign analogues.
In addition, the technology may find application in other projects, including thermonuclear installations. Scientists at BINP SB RAS have already tested prototypes of pumps for pumping hydrogen and deuterium, which have shown high efficiency. The research results are published in the journal "Izvestiya RAN."
The vacuum conditions in the accelerator must be extremely high to ensure the unimpeded movement of the electron beam. The pressure in the chamber will be 12 orders of magnitude (a trillion times) lower than in a normal room. Without this, particles will collide with gas molecules and scatter, which will make the installation impossible to operate.
CCU "SKIF" is a generation 4+ synchrotron radiation source, which is being built in the Novosibirsk region as part of the national project "Science and Universities". The sole contractor for the manufacture of technological equipment for the accelerator complex is BINP SB RAS.
