NASA Space Radiation Laboratory
The NASA Space Radiation Laboratory (NSRL, previously called Booster Applications Facility), is a heavy ion beamline research facility; part of the Collider-Accelerator Department of Brookhaven National Laboratory, located in Upton, New York on Long Island. Its primary mission is to use ion beams (H+to Bi83+) to simulate the cosmic ray radiation fields that are more prominent beyond earth's atmosphere. Overview Jointly managed by the U.S. Department of Energy's Office of Science and NASA's Johnson Space Center, the facility employs beams of heavy ions that simulate the cosmic rays found in space. NSRL also features its own beam line dedicated to radiobiology research, as well as specimen-preparation areas. Although Brookhaven Lab researchers and their colleagues used heavy ion beams for radiobiology research at another Brookhaven accelerator from 1995, the NSRL became operational during summer 2003, and over 75 experimenters from some 20 institutions from the U.S. and abroad have t ...

Upton, New York
Upton is a hamlet and census-designated place (CDP) on Long Island in the town of Brookhaven. It is the home of the Brookhaven National Laboratory and a National Weather Service weather forecast office. Upton is located on eastern Long Island in Suffolk County, New York, United States. The town is so named because it was the site of the U.S. Army's Camp Upton, which was active from 1917 until 1920, and again from 1940 until 1946. During World War II, the camp was rebuilt primarily as an induction center for draftees. The Army was later to use the site as a convalescent and rehabilitation hospital for returning wounded. The 32 megawatt (MW) Long Island Solar Farm (LISF), located in Upton, is the largest photovoltaic array in the eastern United States. The LISF is made up of 164,312 solar panels which provide enough electricity for roughly 4,500 households. The project will cause the abatement of more than 30,000 metric tons of carbon dioxide emissions per year. It earned t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmic Ray
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brookhaven, New York
The Town of Brookhaven is the most populous of the ten towns of Suffolk County, New York, United States. Part of the New York metropolitan area, it is located approximately 50 miles from Manhattan. It is the largest of the state of New York's 932 towns by area (when water area is included), and the second most populous after the Town of Hempstead. The first settlement in what is now Brookhaven was known as Setauket. Founded as a group of agricultural hamlets in the mid-17th century, Brookhaven first expanded as a major center of shipbuilding in the 19th century. Its proximity to New York City facilitated the establishment of resort communities, followed by a post-war population boom. In the 2020 census record, Brookhaven contained 485,773 people. The township is home to two renowned research centers, Stony Brook University and Brookhaven National Laboratory. Combined these two research centers are approximately 50% of the Town's top ten employer's employee count. Tourism is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Energy National Laboratories
The United States Department of Energy National Laboratories and Technology Centers is a system of facilities and laboratories overseen by the United States Department of Energy (DOE) for scientific and technological research. Sixteen of the seventeen DOE national laboratories are federally funded research and development centers administered, managed, operated and staffed by private-sector organizations under management and operating (M&O) contract with DOE (with the National Energy Technology Laboratory being the exception). History The system of centralized national laboratories grew out of the massive scientific endeavors of World War II, in which new technologies such as radar, the computer, the proximity fuse, and the atomic bomb proved decisive for the Allied victory. Though the United States government had begun seriously investing in scientific research for national security in World War I, it was only in late 1930s and 1940s that monumental amounts of resources were ...

Particle Physics Facilities
In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion. The term ''particle'' is rather general in meaning, and is refined as needed by various scientific fields. Anything that is composed of particles may be referred to as being particulate. However, the noun ''particulate'' is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation.

Particle Therapy
Particle therapy is a form of external beam radiotherapy using beams of energetic neutrons, protons, or other heavier positive ions for cancer treatment. The most common type of particle therapy as of August 2021 is proton therapy. In contrast to X-rays (photon beams) used in older radiotherapy, particle beams exhibit a Bragg peak in energy loss through the body, delivering their maximum radiation dose at or near the tumor and minimizing damage to surrounding normal tissues. Particle therapy is also referred to more technically as hadron therapy, excluding photon and electron therapy. Neutron capture therapy, which depends on a secondary nuclear reaction, is also not considered here. Muon therapy, a rare type of particle therapy not within the categories above, has also been attempted however, muons are still most commonly used for imaging, rather than therapy. Method Particle therapy works by aiming energetic ionizing particles at the target tumor. These particles damage t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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, built in 2008 by the European Organization for Nuclear Research (CERN). It can accelerate beams of protons to an energy of 6.5 tera electronvolts (TeV or 1012 eV). Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armed Forces Radiobiology Research Institute
The Armed Forces Radiobiology Research Institute (AFRRI) is an American triservice research laboratory in Bethesda, Maryland chartered by Congress in 1960 and formally established in 1961. It conducts research in the field of radiobiology and related matters which are essential to the operational and medical support of the U.S. Department of Defense (DoD) and the U.S. military services. AFRRI provides services and performs cooperative research with other federal and civilian agencies and institutions. History Department of Defense (DoD) interest in the health effects of exposure to radiological agents (radiobiology), born in the wake of the Manhattan Project, motivated a 1958 Bureau of Medicine and Surgery proposal that a bionuclear research facility be established to study such issues. On June 8, 1960, Public Law 86-500 authorized the construction of such a facility, including a laboratory and vivarium under the Defense Atomic Support Agency (DASA, now the Defense Threat Reduc ...

Health Threat From Cosmic Rays
Health threats from cosmic rays are the dangers posed by cosmic rays to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere. They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft, but space radiation health risks also occur for missions in low Earth orbit such as the International Space Station (ISS). In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars. The deep-space radiation environment The radiation environment of deep space is different from that on the Earth's surface or in low Earth orbit, due to the much larger flux of high-energy galactic cosmic rays (GCRs), along with radiation from solar proton events (SPEs) and the radiation belts. Galactic cosmic rays (GCRs) consist of high energy protons (85%), alpha particles (14%) and oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Orbits
Summary A simple list of just the common orbit abbreviations. List of abbreviations of common Earth orbits List of abbreviations of other orbits Classifications The following is a list of types of orbits: Centric classifications * Galactocentric orbit: An orbit about the center of a galaxy. The Sun follows this type of orbit about the Galactic Center of the Milky Way. * Heliocentric orbit: An orbit around the Sun. In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. * Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites. * Lunar orbit (also selenocentric orbit): An orbit around Earth's Moon. * Areocentric orbit: An orbit around the planet Mars, such as that of its moons or artificial satellites.
