Cherenkov Array At Themis
The Cherenkov Array at Themis (CAT) was an imaging atmospheric Cherenkov telescope (IACT) for detection of very-high-energy gamma rays (~200 GeV to a few tens of TeV). The project started operation in Autumn 1996 on the site of the former solar plant Thémis, France.

Imaging Atmospheric Cherenkov Telescope
Imaging is the representation or reproduction of an object's form; especially a visual representation (i.e., the formation of an image). Imaging technology is the application of materials and methods to create, preserve, or duplicate images. Imaging science is a multidisciplinary field concerned with the generation, collection, duplication, analysis, modification, and visualization of images,Joseph P. Hornak, ''Encyclopedia of Imaging Science and Technology'' (John Wiley & Sons, 2002) including imaging things that the human eye cannot detect. As an evolving field it includes research and researchers from physics, mathematics, electrical engineering, computer vision, computer science, and perceptual psychology. '' Imagers'' are imaging sensors. Imaging chain The foundation of imaging science as a discipline is the "imaging chain" – a conceptual model describing all of the factors which must be considered when developing a system for creating visual renderings (images).

Very-high-energy Gamma Ray
A very-high-energy gamma ray (VHEGR) is Gamma ray, gamma radiation with photon energy, photon energies of 100 GeV (gigaelectronvolt) to 100 TeV (teraelectronvolt), i.e., 1011 to 1014 electronvolts. This is approximately equal to wavelengths between 10−17 and 10−20 meters, or frequencies of 2 × 1025 to 2 × 1028 Hz. Such energy levels have been detected from emissions from astronomical sources such as some binary star systems containing a compact object. For example, radiation emitted from Cygnus X-3 has been measured at ranges from GeV to Exa-, exaelectronvolt-levels. Other astronomical sources include BL Lacertae, 3C 66A Markarian 421 and Markarian 501. Various other sources exist that are not associated with known bodies. For example, the High Energy Stereoscopic System, H.E.S.S. catalog contained 64 sources in November 2011. Detection Instruments to detect this radiation commonly measure the Cherenkov radiation produced by secondary particles generated from an energetic p ...

Themis (solar Power Plant)
The THEMIS solar power tower is a research and development centre focused on solar energy. It is located near the village of Targasonne, in the department of Pyrénées-Orientales, south of France, 3 kilometres from the world's largest Odeillo solar furnace, solar furnace in Odeillo. Siting of the plant THEMIS solar power tower, owned by the General Council of the Pyrénées-Orientales, was strategically located in the region of Cerdanya, in the Pyrénées-Orientales, because the conditions are excellent for solar energy. First, Cerdanya has almost 2400 hours of sunshine a year; second, there is a very low wind limiting the time of disruption of the plant; third, the site is at a high elevation providing stronger sunlight. The land chosen for the plant is on a slope between 6° and 18°, which is suitable for a power tower. THEMIS research and development centre Research and development is focused on solar energy, and THEMIS is a research facility as well as a Photo ...

INSPIRE-HEP
INSPIRE-HEP is an open access digital library for the field of high energy physics (HEP). It is the successor of the Stanford Physics Information Retrieval System (SPIRES) database, the main literature database for high energy physics since the 1970s. History SPIRES was (in addition to the CERN Document Server (CDS), arXiv and parts of Astrophysics Data System) one of the main Particle Information Resources. A survey conducted in 2007 found that SPIRES database users wanted the portal to provide more services than the, at that time, already 30-year-old system could provide. On the second annual Summit of Information Specialists in Particle Physics and Astrophysics in May 2008, the physics laboratories CERN, DESY, SLAC and Fermilab therefore announced that they would work together to create a new Scientific Information System for high energy physics called INSPIRE. It interacts with other HEP service providers like arXiv.org, Particle Data Group, NASA The National A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
