Vladimir Aleksandrovich Teplyakov (Russian: Владимир Александрович Тепляков) (November 6, 1925 – December 10, 2009) was a Russian physicist best known for his work on particle accelerators. He, working with I.M. Kapchinsky, invented the principle of the Radio Frequency Quadrupole (RFQ), which revolutionized the acceleration of low energy ion beams.[1]


V.A. Teplyakov was born in Tambov, Russian SFSR, USSR, on November 6, 1925. He was drafted into the Red Army in January 1943 to fight in the Second World War, serving as part of the 3rd Ukrainian Front, and participated in the Vienna Offensive.[2] After the war, he graduated from the All-Union Correspondence Polytechnic Institute in Moscow and got a job at the Institute of Chemical Physics of the Soviet Academy of Sciences.[3] From 1959 to 1966 he worked at Chelyabinsk-70, where he studied high-current proton linear accelerators. In 1966, he and his colleagues were transferred to the Institute for High Energy Physics (IHEP) in Protvino, where he was in charge of the I-100, a 100 MeV Alvarez drift-tube linac, which was an injector to the U-70, a 70 GeV proton synchrotron, the world's largest particle accelerator at that time.[1][4]

In 1969, while working at IHEP, Teplyakov and Kapchinsky developed the concept of the radio frequency quadrupole. This concept creates a "double gap" using an intermediate electrode, creating separate accelerating and focusing parts. This allows for the dimensions of drift tubes to decrease and switch to small cavities, which are more cost-effective at low ion velocities. Teplyakov subsequently developed several RFQ drift-tube structures and RF cavities to drive them.[1][5][6]

For the rest of his life, Teplyakov continued to work at IHEP, continuing his work on particle accelerators. Teplyakov eventually became Deputy Director of Science at IHEP. He died on December 10, 2009 in Protvino. He is the author of more than 100 scientific papers and inventions, and is the co-author of the book Linear Accelerators of Ions.[3][7]

Honours and awards[edit]

Teplyakov and Kapchinsky were awarded the Lenin Prize and the US Particle Accelerator School Prize for Achievement in Accelerator Physics and Technology in 1988 for the development of the RFQ.[8][1] For his work in the field of physics, Teplyakov also received the Order of Lenin and the Order of the October Revolution. During World War II, Teplyakov was awarded the Order of Glory, 3rd class, the Order of the Patriotic War, 2nd class, the Medal For Courage, and the Medal "For the Capture of Vienna".[1][3] In 2006, The European Physical Society Accelerator Group awarded him the prize "for outstanding work in the accelerator field with no age limit".[9] Teplyakov was one of the first to receive the title "Veteran of Atomic Energy and Industry" and also received the title "Honored Worker of Science and Technology".[3]
