Francis Perrin (physicist)
Francis Perrin (17 August 1901 – 4 July 1992) was a French physicist, the son of Nobel prize-winning physicist Jean Perrin. Physicist Francis Perrin was born in Paris and attended École Normale Supérieure in Paris. In 1928 he obtained a doctorate in mathematical sciences from the faculté des sciences of Paris, based upon a thesis on Brownian motion and became a faculty member of Collège de France. In 1933, in connection with the neutrino, Francis Perrin estimated that "the mass must be null—or at least small compared to the mass of the electron". Subsequently he worked at the Collège de France on the fission of uranium. With Frédéric Joliot and his group, he established in 1939 the possibility of nuclear chain reactions and nuclear energy production. He was professor at the Collège de France in the chair of Atomic and Molecular Physics from 1946 to 1972. He was the French high-commissioner for atomic energy from 1951 to 1970. In 1972, he discovered the Oklo natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commissariat à L'énergie Atomique
The French Alternative Energies and Atomic Energy Commission or CEA (French: Commissariat à l'énergie atomique et aux énergies alternatives), is a French public government-funded research organisation in the areas of energy, defense and security, information technologies and health technologies. The CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research. CEA is headed by a board headed by the general administrator (currently François Jacq since 20 April 2018), advised by the high-commissioner for atomic energy (currently Patrick Landais). Its yearly budget amounts to €5.1 billion and its permanent staff is slightly over 20,500 persons. It owned Areva. CEA was created in 1945; since then, the successive high-commissioners have been Frédéric Joliot-Curie, Francis Perrin, Jacques Yvon, Jean Teillac, Raoul Dautry, René Pellat, Bernard Bigot, Daniel Verwaerde and François Jacq.

Pierre Victor Auger
Pierre Victor Auger (; 14 May 1899 – 24 December 1993) was a French physicist, born in Paris. He worked in the fields of atomic physics, nuclear physics, and cosmic ray physics. He is famous for being one of the discoverers of the Auger effect, named after him. Early life Pierre's father was chemistry professor Victor Auger. Pierre Auger was a student at the École normale supérieure in Paris from 1919 to 1922, the year when he passed the agrégation of physics. He then joined the physical chemistry laboratory of the faculté des sciences of the University of Paris under the direction of Jean Perrin to work there on the photoelectric effect. Career In 1926 he obtained his doctorate in physics from the University of Paris. In 1927, he was named assistant to the faculté des sciences of Paris and, at the same time, adjoint chief of service to l'Institut de biologie physico-chimique.

Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

Saclay Nuclear Research Centre
The CEA Paris-Saclay (formerly CEA Saclay) center is one of nine centers belonging to the French Alternative Energies and Atomic Energy Commission (CEA). The Saclay site hosts the administrative headquarters of the CEA. Historically, it was the heart of French nuclear research since Frederic Joliot-Curie founded it after the Second World War. Its campus was designed by the architect Auguste Perret. It is now a part of the confederation of Paris-Saclay University, along with CentraleSupélec, CNRS, ENS Paris-Saclay, HEC Paris, IHES, etc. Research The complex employs more than 7,000 scientists (including other smaller Île-de-France sites) and is located in the Essonne department of northern France, south of Paris on the Saclay Plateau. The research carried out ranges from fundamental research to applied research and, thanks to the Orpheus research reactor, lasers and magnetic resonance research into the State of Matter. Research at Saclay is focussed on different topi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerboise Bleue
''Gerboise Bleue'' (; ) was the codename of the first French nuclear test. It was conducted by the Nuclear Experiments Operational Group (GOEN), a unit of the Joint Special Weapons Command on 13 February 1960, at the Saharan Military Experiments Centre near Reggane, French Algeria in the Sahara desert region of Tanezrouft, during the Algerian War. General Pierre Marie Gallois was instrumental in the endeavour, and earned the nickname of ''père de la bombe A'' ("father of the A-bomb"). Name ''Gerboise'' is the French word for jerboa, a desert rodent found in the Sahara. The color blue (''Bleue'') adjuncted is said to come from the first colour of the French Flag. Test Explosion On April 11, 1958, French Prime Minister Félix Gaillard ordered a nuclear test in the first quarter of 1960. President Charles de Gaulle reaffirmed the decision after the French Fourth Republic collapsed in the May 1958 crisis. On 13 February 1960 at 7:04:00 UTC, the plutonium filled bomb was d ...

Bertrand Goldschmidt
Bertrand Goldschmidt (2 November 1912 – 11 June 2002) was a French chemist. He is considered one of the fathers of the French atomic bomb, which was tested for the first time in 1960 in the nuclear test Gerboise Bleue. Biography Bertrand Goldschmidt was born in Paris on 2 November 1912 to a French mother and a Belgian father of Jewish origin.

Yves Rocard
Yves-André Rocard (22 May 1903 – 16 March 1992) was a French physicist who helped develop the atomic bomb for France. Rocard was born in Vannes. After obtaining a double doctorate in mathematics (1927) and physics (1928) he was awarded the professorship in electronic physics at the École normale supérieure in Paris. As a member of a Resistance group during the Second World War he flew to the UK in a small plane as part of a dangerous mission, and was able to provide British intelligence with invaluable information. There he met up with Charles de Gaulle who named him Director of Research in the Forces navales françaises libres (the Navy of Free France). He became particularly interested in the detection of solar radio emissions by British Radar, which were causing military problems by jamming detection during periods of high emission, and was able to create a new radio navigational beam station. As research director, Rocard followed the French troops entering Germany. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
