Lev Artsimovich
Lev Andreyevich Artsimovich ( Russian: Лев Андреевич Арцимович, February 25, 1909 – March 1, 1973), also transliterated Arzimowitsch, was a Soviet physicist known for his contributions to the Tokamak— a device that produces controlled thermonuclear fusion power. Prior to conceiving the idea on nuclear fusion, Artsimovich participated in the former Soviet program of nuclear weapons, and was a recipient of many former Soviet honors and awards. Biography Artsimovich was born on 25 February 1909 in Moscow in the Russian Empire. His family had Polish nobility roots; nonetheless, he was described as Russian by his autobiographer in 1985. His grandfather, a professor, was exiled to Siberia after the Polish uprising against Tsarist Russia in 1863 and married a Russian woman, later settling in Smolensk. His father was educated at Lviv University; his mother was a pianist trained in Switzerland. In 1923, Soviet authorities moved the Artsimovich family (due t ...

Acoustic Paramagnetic Resonance
In acoustics, acoustic paramagnetic resonance (APR) is a phenomenon of resonant absorption of sound by a system of magnetic particles placed in an external magnetic field. It occurs when the energy of the sound wave quantum becomes equal to the splitting of the energy levels of the particles, the splitting being induced by the magnetic field. APR is a variation of electron paramagnetic resonance (EPR) where the acoustic rather than electromagnetic waves are absorbed by the studied sample. APR was theoretically predicted in 1952, independently by Semen Altshuler and Alfred Kastler, and was experimentally observed by W. G. Proctor and W. H. Tanttila in 1955. History After discovery of EPR in 1944, Evgeny Zavoisky predicted that the resonance phenomenon should not be restricted to radio or microwave absorption but could be extended to the sound waves. This idea was theoretically developed by his collaborator Semen Altshuler in 1952 and independently by Alfred Kastler; whereas Altsh ...

Electron Paramagnetic Resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes and organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford. Theory Origin of an EPR signal Every electron has a magnetic moment and spin quantum number s = \tfrac , with magnetic components m_\mathrm = + \tfrac or m_\mathrm = - \tfrac . In the presence of an external magnetic field with strength B_\mathrm , the electron's magnetic moment aligns itself either antiparallel ( m_\mathrm = - \tfrac ) or parallel ( m_\mathrm = + \tfrac ) to the fie ...

Semen Altshuler
Semyon Alexandrovich Altshuler (also Altshuller, Al'tshuler or Al'shuller; ; ; September 24, 1911 – January 24, 1983) was a Soviet physicist known for his work in resonance spectroscopy and in particular for theoretical prediction of acoustic paramagnetic resonance in 1952.Kochelaev p.100 Early years Altshuler was born in 1911 in Vitebsk, in the Russian Empire. He finished school in Nizhny Novgorod and later moved to Kazan, where he spent most of his life. In 1928, he entered the physics faculty of the Kazan University aiming to study theoretical physics. He graduated in 1932 and obtained a post-graduate scholarship, but had to change university due to the scholarship rules. He moved to Moscow to study with Igor Tamm whom he admired for his books on electricity and magnetism. In 1934, Altshuler and Tamm published a famous article which predicted the existence of the magnetic moment of neutron and correctly estimated its value and sign. This idea was so unusual then that even Ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Physicist
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields such as nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Abram Alikhanov
Abram Isaakovich Alikhanov (; , né Alikhanian; 8 December 1970) was a Soviet experimental physicist of Armenian origin who specialized in particle and nuclear physics. He was one of the Soviet Union's leading physicists. Before joining the Soviet atomic bomb project, Alikhanov studied X-rays and cosmic rays. Between 1945 and 1968, he directed the Institute for Theoretical and Experimental Physics (ITEP) in Moscow, which was named after him in 2004. He led the development of both the first research and the first industrial heavy water reactors in the Soviet Union. They were commissioned in 1949 and 1951, respectively. He was also a pioneer in Soviet accelerator technology. In 1934 he and Igor Kurchatov created a "baby cyclotron", the first "cyclotron" operating outside of Berkeley, California. He was the driving force behind the construction of the 70 GeV synchrotron in Serpukhov (1967), the largest in the world at the time. His brother, Artem Alikhanian, was based in So ...

Spark Chamber
A spark chamber is a particle detector: a device used in particle physics for detecting electrically charged Subatomic particle, particles. They were most widely used as research tools from the 1930s to the 1960s and have since been superseded by other technologies such as drift chambers and semiconductor detector, silicon detectors. Today, working spark chambers are mostly found in science museums and educational organisations, where they are used to demonstrate aspects of particle physics and astrophysics. Spark chambers consist of a stack of metal plates placed in a sealed box filled with a gas such as helium, neon or a mixture of the two. When a charged particle from a cosmic ray travels through the box, it ionises the gas between the plates. Ordinarily this ionisation would remain invisible. However, if a high enough voltage can be applied between each adjacent pair of plates before that ionisation disappears, then sparks can be made to form along the trajectory taken by the r ...
