The Sudbury Neutrino Observatory (SNO) was a neutrino observatory located 2100 m underground in Vale's Creighton Mine in Sudbury, Ontario, Canada. The detector was designed to detect solar neutrinos through their interactions with a large tank of heavy water.
SLAC National Accelerator Laboratory, originally named Stanford Linear Accelerator Center, is a United States Department of Energy National Laboratory operated by Stanford University under the programmatic direction of the U.S. Department of Energy Office of Science and located in Menlo Park, California. It is the site of the Stanford Linear Accelerator, a 3.2 kilometer (2-mile) linear accelerator constructed in 1966 and shut down in the 2000s, which could accelerate electrons to energies of 50 GeV.
Solar Energy Generating Systems (SEGS) is a concentrated solar power plant in California, United States. With the combined capacity from three separate locations at 354 megawatt (MW), it is the world's second largest solar thermal energy generating facility, after the commissioning of the even larger Ivanpah facility in 2014. It consists of nine solar power plants in California's Mojave Desert, where insolation is among the best available in the United States. SEGS I–II (44 MW) are located at Daggett, SEGS III–VII (150 MW) are installed at Kramer Junction, and SEGS VIII–IX (160 MW) are placed at Harper Lake. NextEra Energy Resources operates and partially owns the plants located at Kramer Junction. On January 26, 2018, the SEGS VIII and IX at Harper Lake were sold to renewable energy company Terra-Gen, LLC. A tenth plant had been in construction and SEGS XI and SEGS XII had been planned by Luz Industries, but the developer filed for bankruptcy in 1992, because it was unable to secure construction financing.
The INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) is a space telescope for observing gamma rays of energies up to 8 MeV. It was launched by the European Space Agency (ESA) into Earth orbit in 2002, and is designed to provide imaging and spectroscopy of cosmic sources. In the MeV energy range, it is the most sensitive gamma ray observatory in space. It is sensitive to higher energy photons than X-ray instruments such as NuSTAR, the Neil Gehrels SWIFT Observatory, XMM-Newton, and lower than other gamma-ray instruments such Fermi and HESS.
Daggett is an unincorporated community located in San Bernardino County, California in the United States. The town is located on Interstate 40 ten miles (16 km) east of Barstow. The town has a population of about 200. The ZIP code is 92327 and the community is inside area code 760.
The SOLAR Project consists of the Solar One, Solar Two and Solar Tres solar thermal power plants based in the Mojave Desert, United States and Andalucía, Spain. The US Department of Energy (DOE) and a consortium of US utilities built the country's first two large-scale, demonstration solar power towers in the desert near Barstow, California.
The THEMIS solar power tower is a research and development centre focused on solar energy. It is located near the village of Targassonne, in the department of Pyrénées-Orientales, south of France, 3 kilometres from the world's largest solar furnace in Odeillo.
A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses. They were used for both terrestrial applications and astronomy.
There are several solar power plants in the Mojave Desert which supply power to the electricity grid. Insolation in the Mojave Desert is among the best available in the United States, and some significant population centers are located in the area. These plants can generally be built in a few years because solar plants are built almost entirely with modular, readily available materials. Solar Energy Generating Systems (SEGS) is the name given to nine solar power plants in the Mojave Desert which were built in the 1980s, the first commercial solar plant. These plants have a combined capacity of 354 megawatts (MW) which made them the largest solar power installation in the world, until Ivanpah Solar Power Facility was finished in 2014.
CACTUS was a ground-based, Air Cherenkov Telescope (ACT) located outside Daggett, California, near Barstow. It was originally a solar power plant called Solar Two, but was converted to an observatory starting in 2001. The first astronomical observations started in the fall of 2004. However, the facility had its last observing runs in November 2005 as funds for observational operations from the National Science Foundation were no longer available. The facility was operated by the University of California, Davis but owned by Southern California Edison. It was demolished in 2009.
Milagro was a ground-based water Cherenkov radiation telescope situated in the Jemez Mountains near Los Alamos, New Mexico at the Fenton Hill Observatory site. It was primarily designed to detect gamma rays but also detected large numbers of cosmic rays. It operated in the TeV region of the spectrum at an altitude of 2530 m. Like conventional telescopes, Milagro was sensitive to light but the similarities ended there. Whereas "normal" astronomical telescopes view the universe in visible light, Milagro saw the universe at very high energies. The light that Milagro saw was about 1 trillion times more energetic than visible light. While these particles of light, known as photons, are the same as the photons that make up visible light, they behave quite differently due to their high energies.
SGR 0525−66 is a soft gamma repeater (SGR), located in the Super-Nova Remnant (SNR) 0525−66.1, otherwise known as N49, in the Large Magellanic Cloud. It was the first soft gamma repeater discovered, and as of 2015, the only known located outside our galaxy. First detected in March 1979, it was located by using the measurement of the arrival time differences of the signal by the set of artificial satellites equipped with gamma ray detectors. The association with N49 can only be indirect: it seems clear that soft gamma repeaters form in young stellar clusters. It is not certain that the explosion that gave birth to SGR 0525-66 is also the one that produced the remnant N49.
The PS20 solar power plant (PS20) solar power plant is a solar thermal energy plant in Sanlucar la Mayor near Seville in Andalusia, Spain. It was the world's most powerful solar power tower until the Ivanpah Solar Power Facility in California became operational in 2014. The 20 megawatt (MW) solar power tower produces electricity with large movable mirrors called heliostats.
The solar power tower, also known as 'central tower' power plants or 'heliostat' power plants or power towers, is a type of solar furnace using a tower to receive the focused sunlight. It uses an array of flat, movable mirrors to focus the sun's rays upon a collector tower. Concentrated solar thermal is seen as one viable solution for renewable, pollution-free energy.
eSolar is a privately held company that develops concentrating solar power (CSP) plant technology. The company was founded by the Pasadena-based business incubator Idealab in 2007 as a developer of CSP plant technology. The company aims to develop a low cost alternative to fossil fuels through a combination of small heliostats, modular architecture, and a high-precision sun-tracking system. In October 2017, an article in GreenTech Media suggested that eSolar ceased business in late 2016.
The Ivanpah Solar Electric Generating System is a concentrated solar thermal plant in the Mojave Desert. It is located at the base of Clark Mountain in California, across the state line from Primm, Nevada. The plant has a gross capacity of 392 megawatts (MW). It deploys 173,500 heliostats, each with two mirrors focusing solar energy on boilers located on three 459 ft tall solar power towers. The first unit of the system was connected to the electrical grid in September 2013 for an initial synchronisation test. The facility formally opened on February 13, 2014. In 2014, it was the world's largest solar thermal power station.
Practical Solar, Inc. is an American manufacturer of heliostats used for concentrating solar power, as well as for residential and commercial natural lighting (daylighting) applications. The company, located in Boston, Massachusetts, introduced its heliostat system for sale in February 2009.
Sierra SunTower was a 5 MW commercial concentrating solar power (CSP) plant built and operated by eSolar. The plant is located in Lancaster, California. As of mid-August, 2018, the two towers that were the center of the facility are no longer standing. The plant, however, is still present.
