Raphael M. Littauer
Raphael Max Littauer (November 28, 1925 – October 19, 2009) was an American physicist who was a longtime Professor of Physics and Nuclear Studies at Cornell University. He was involved in the development of several particle accelerators there, in particular the 10 GeV electron synchrotron at the Wilson Synchrotron Lab in the late 1960s, where he devised a distributed, multiplexed control system for it, and the Cornell Electron Storage Ring (CESR) in the late 1970s and early 1980s, where his scheme to create pretzel-shaped orbits to increase the number of particle bunches in circulation contributed significantly to CESR having the highest Luminosity (scattering theory), luminosity of any accelerator of its era. Littauer was also known for his teaching, including the design, implementation, and installation of one of the earliest and most successful classroom response systems. An opposition to United States involvement in the Vietnam War, active opponent of the Vietnam War, he l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leipzig
Leipzig (, ; ; Upper Saxon: ; ) is the most populous city in the States of Germany, German state of Saxony. The city has a population of 628,718 inhabitants as of 2023. It is the List of cities in Germany by population, eighth-largest city in Germany and is part of the Central German Metropolitan Region. The name of the city is usually interpreted as a Slavic term meaning ''place of linden trees'', in line with many other Slavic placenames in the region. Leipzig is located about southwest of Berlin, in the southernmost part of the North German Plain (the Leipzig Bay), at the confluence of the White Elster and its tributaries Pleiße and Parthe. The Leipzig Riverside Forest, Europe's largest intra-city riparian forest, has developed along these rivers. Leipzig is at the centre of Neuseenland (''new lake district''). This district has Bodies of water in Leipzig, several artificial lakes created from former lignite Open-pit_mining, open-pit mines. Leipzig has been a trade city s ...

United States Citizen
Citizenship of the United States is a legal status that entails Americans with specific rights, duties, protections, and benefits in the United States. It serves as a foundation of fundamental rights derived from and protected by the Constitution and laws of the United States, such as freedom of expression, due process, the rights to vote, live and work in the United States, and to receive federal assistance. There are two primary sources of citizenship: birthright citizenship, in which persons born within the territorial limits of the United States (except American Samoa) are presumed to be a citizen, or—providing certain other requirements are met—born abroad to a United States citizen parent, and naturalization, a process in which an eligible legal immigrant applies for citizenship and is accepted. The first of these two pathways to citizenship is specified in the Citizenship Clause of the Fourteenth Amendment of the Constitution which reads: The second is provide ...

Electrostatic Separator
An electrostatic separator is a device for separating particles by mass in a low energy charged beam. An example is the electrostatic precipitator used in coal-fired power plants to treat exhaust gas, removing small particles that cause air pollution. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material. An industrial process used to separate large amounts of material particles, electrostatic separating is most often used in the process of sorting mineral ore. This process can help remove valuable material from ore, or it can help remove foreign material to purify a substance. In mining, the process of crushing mining ore into particles for the purpose of separating minerals is called beneficiation. Generally, electrostatic charges are used to attract or repel differently charged material. When electrostatic separation uses the force of attraction to sort particles, conducting particles stick to an oppositely charged ob ...

Storage Ring
A storage ring is a type of circular particle accelerator in which a continuous or pulsed particle beam may be kept circulating, typically for many hours. Storage of a particular particle depends upon the mass, momentum, and usually the charge of the particle to be stored. Storage rings most commonly store electrons, positrons, or protons. Storage rings are most often used to store electrons that radiate synchrotron radiation. Over 50 facilities based on electron storage rings exist and are used for a variety of studies in chemistry and biology. Storage rings can also be used to produce polarized high-energy electron beams through the Sokolov-Ternov effect. The best-known application of storage rings is their use in particle accelerators and in particle colliders, where two counter-rotating beams of stored particles are brought into collision at discrete locations. The resulting subatomic interactions are then studied in a surrounding particle detector. Examples of such faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schoellkopf Field
Schoellkopf Field is a 21,500-capacity stadium at Cornell University's Ithaca campus that opened in 1915 and is used for the Cornell Big Red football, sprint football and lacrosse teams. It is located just north of Cascadilla Creek on the southern end of the campus, next to Hoy Field and Lynah Rink; Schoellkopf Memorial Hall, adjacent to the stadium, contains the Robison Hall of Fame Room, the hall of fame for Cornell athletics. History During the 1800s, Cornell athletic teams played on Percy Field, located where Ithaca High School now stands. As the university and town grew, the need for a larger, dedicated stadium on campus became apparent. Following the death of former Cornell football player and head football coach Henry Schoellkopf in 1912, his close friend, Willard Straight, donated $100,000 () to construct the Schoellkopf Memorial Hall in honor of Henry Schoellkopf. The building was completed in 1913. In response to Straight's gift, members of the Schoellkopf fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electron Synchrotron
A synchrotron is a particular type of cyclic particle accelerator, descended from the cyclotron, in which the accelerating particle beam travels around a fixed closed-loop path. The strength of the magnetic field which bends the particle beam into its closed path increases with time during the accelerating process, being ''synchronized'' to the increasing kinetic energy of the particles. The synchrotron is one of the first accelerator concepts to enable the construction of large-scale facilities, since bending, beam focusing and acceleration can be separated into different components. The most powerful modern particle accelerators use versions of the synchrotron design. The largest synchrotron-type accelerator, also the largest particle accelerator in the world, is the Large Hadron Collider (LHC) near Geneva, Switzerland, completed in 2008 by the European Organization for Nuclear Research (CERN). It can accelerate beams of protons to an energy of 7 teraelectronvolts (TeV or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colliding Beam Accelerator
In physics, a collision is any event in which two or more bodies exert forces on each other in a relatively short time. Although the most common use of the word ''collision'' refers to incidents in which two or more objects collide with great force, the scientific use of the term implies nothing about the magnitude of the force. Types of collisions Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity). The magnitude of the velocity difference just before impact is called the closing speed. All collisions conserve momentum. What distinguishes different types of collisions is whether they also conserve kinetic energy of the system before and after the collision. Collisions are of two types: #Elastic collision If all of the total kinetic energy is conserved (i.e. no energy is releas ...
