Extractions: Cherenkov, Pavel Alekseyevich (1904-1990), a Russian physicist, made important contributions to the field of nuclear physics with his discovery of Cherenkov radiation. Cherenkov shared the 1958 Nobel Prize in physics with Russian scientists Ilya M. Frank and Igor Yevgenevich Tamm. The three men were the first Russian scientists to win a Nobel Prize in physics. At graduate school, Cherenkov worked under the supervision of Sergei I. Vavilov, who suggested that Cherenkov study what happens when high-energy particles penetrate a liquid. Cherenkov showed that, in most cases, fluorescence was responsible for the light produced by a liquid. As the liquid absorbs the high-energy radiation, the incoming energy excites the atoms and causes them to reach a higher energy state. The atoms quickly return to a lower energy state, however, and the difference between the higher and lower state is emitted as electromagnetic radiation in some cases appearing as light. When Cherenkov tried the procedure with gamma rays from radium, he observed a blue glow that he did not readily understand. To discover the underlying cause, he conducted a series of experiments to test the light under a variety of conditions. He had to rely on his eyesight to measure the light because he lacked high-energy radiation detectors. Since he had only weak sources of radium, he had to sensitize his eyes to see the fleeting blue glow and thus started his workday by sitting in a totally darkened room for an hour.

En 1953 il a été confirmé dans le rang universitaire de Professeur de Physique Expérimentale et depuis 1959 il a contrôlé le photo-meson traite le laboratoire. Il a enseigné dans des instituts de l'étude plus haute pendant quatorze ans. C'était en 1934, pendant qu'il travaillait sous S.I. Vavilov, que Cerenkov a observé l'émission de lumière bleue d'une bouteille d'eau soumise au bombardement radioactif. Ce "Cerenkov effectuent", associé aux particules atomiques chargées se déplaçant aux vitesses plus haut que la vitesse de la lumière, prouvée pour être très important dans le travail expérimental suivant dans la physique nucléaire et pour l'étude de rayons cosmiques. Le détecteur Cerenkov est devenu un morceau standard d'équipement dans la recherche atomique pour observer l'existence et la vitesse de particules ultra-rapides et le dispositif a été installé dans Sputnik III.

Pavel Alekseyevich Cherenkov Pavel Alekseyevich Cherenkov (Russian Павел ÐлекÑеевич Черенков) (July 28, 1904 January 6, 1990) was a Soviet physicist and Nobel Prize winner. http://www.mlahanas.de/Physics/Bios/PavelACherenkov.html
Extractions: He graduated from the Department of Physics and Mathematics of Voronezh State University in 1928, in 1930 he took a post as a senior researcher in the Lebedev Institute of Physics. Later Cherenkov was promoted to the section leader, and in 1940 he was awarded the degree of Doctor of Physico-Mathematical Sciences. In 1953 he was confirmed as Professor of Experimental Physics. Since 1959 he headed the photo-meson processes laboratory. He remained a professor for fourteen years. In 1970 he became an Academician of the USSR Academy of Sciences. In 1934, while working under S.I. Vavilov, Cherenkov observed the emission of blue light from a bottle of water subjected to radioactive bombardment. This Cerenkov effect, associated with charged atomic particles moving at velocities higher than the speed of light in the local medium, proved to be of great importance in subsequent experimental work in nuclear physics, and for the study of cosmic rays. The Cerenkov detector has become a standard piece of equipment in atomic research for observing the existence and velocity of high-speed particles. The device was installed in Sputnik III.

Extractions: Reference Desk Encyclopedia Cherenkov radiation or Cerenkov radiation [for P. A. Cherenkov ], light emitted by a transparent medium when charged particles pass through it at a speed greater than the speed of light in the medium. The effect, discovered by Cherenkov in 1934 while he was studying the effects of gamma rays on liquids and explained in 1937 by I. E. Tamm and I. M. Frank, is analogous to the creation of a sonic boom when an object exceeds the speed of sound in a medium. The light is emitted only in directions inclined at a certain angle to the direction of the particles' motion dependent upon the particles' momentum. Thus, by simply measuring the angle between the radiation and the path of the particles, the particles' speed may be determined. The effect is used in the Cherenkov counter, a device for detecting fast particles and determining their speeds or distinguishing between particles of different speeds.

Extractions: Soviet physicist who shared the 1958 Nobel Prize for Physics with fellow Soviet scientists Igor Y. Tamm and Ilya M. Frank for their investigation of the phenomenon called Cherenkov radiation. Cherenkov discovered that light is emitted by electrons as they pass through a transparent medium at a speed higher than the speed of light in that medium. Cherenkov graduated from Voronezh State University in 1928; he later became a research student at the P.N. Lebedev Physical Institute of the Academy of Sciences of the Soviet Union (now the Russian Academy of Sciences). In 1934, in the course of his dissertation research, he observed that electrons produced a faint blue glow when passing through a transparent liquid at high velocity. This phenomenon, which was interpreted by Tamm and Frank, led to the development of the Cherenkov counter, or Cherenkov detector, which was later used extensively in experimental nuclear and particle physics. Cherenkov continued to do research in nuclear physics at the Lebedev Institute, where he became a full professor in 1959. Main Page About Us http://www.nobel-winners.com/
