Callio
Callio is a project to oversee the reuse of the Pyhäsalmi Mine, located in the Pyhäjärvi, town of Pyhäjärvi in Finland. Callio aims to make Pyhäsalmi Mine an operating environment for businesses and an underground facility, underground research facility. Callio is a joint project by the town of Pyhäjärvi and the University of Oulu. In 2017 the facility joined the "Baltic Sea Underground Facilities and Innovation Network"BSUIN. The word ”callio” is an Anglicisation, anglicised version of the Finnish word ”kallio” [kael-lee-oh], meaning crystalline bedrock. Facilities and access Callio is an umbrella organization for a variety of non-mining activities in and around the mine. Of these, Callio Lab oversees scientific research and development. Proposed new activities include a secure underground data center, pumped hydroelectrical Pumped-storage hydroelectricity, energy storage, plant and fungus growing laboratories, breeding sites for insects and fish, and several o ...

Centre For Underground Physics In Pyhäsalmi
Centre for Underground Physics in Pyhäsalmi or CUPP is an underground physics laboratory located in Pyhäjärvi, Finland. It occupies part of the CallioLab research and development laboratories, overseen by Callio Pyhäsalmi. It is located in the deepest base metal mine of Europe, the Pyhäsalmi Mine ( deep; the laboratory has sites at many levels of the mine) and uses some of the infrastructure of the mine. The laboratory is made to study neutrino-physics and cosmic radiation, as well as other subjects (ranging outside physics, like geology or biology) that benefit from the underground laboratory's unique conditions. The reason that the laboratory is underground is because in the particle detectors, the background radiation is a problem, which can be solved by placing the laboratory underground so that the background radiation is absorbed in the rock above. The centre is currently (2018) hosting the EMMA experiment and the C14 experiment. It was a candidate site for the prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyhäjärvi
Pyhäjärvi (1993–1995 ''Pyhäsalmi'') is a town and municipality in the south of Northern Ostrobothnia region, Finland. Pyhäjärvi also borders the Northern Savonia and Central Finland regions. The town belongs to the subregion of Nivala–Haapajärvi. Its seat is in ''Pyhäsalmi''. Neighbouring municipalities are Haapajärvi, Kiuruvesi, Kärsämäki, Pielavesi, Pihtipudas and Pyhäntä. As the highway 4 ( E75), the highway 27 and the Ylivieska–Iisalmi railway all run through the town, Pyhäjärvi is well situated in an intersection of communication and transport services. The town has also an airfield. The town of Pyhäjärvi was founded in 1866, and it was then named after Lake Pyhäjärvi, a lake of and rich in fish. Pyhäjärvi became officially a town in January 1993. The town has inhabitants (), of whom some 60 percent live in the two population centres Pyhäsalmi and Ruotanen. It is the second smallest town of Finland in term of population after Kaskinen in the O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Large Apparatus Studying Grand Unification And Neutrino Astrophysics
Large Apparatus studying Grand Unification and Neutrino Astrophysics or LAGUNA is or was a European project aimed to develop the next-generation, very large volume underground neutrino observatory. The detector should be much bigger and more sensitive than any previous detector, and make new discoveries in the field of particle and astroparticle physics. The project involves 21 European institutions in 10 European countries, and brings together over 100 scientists. As of 2011, the project was assessing the feasibility of developing the observatory-infrastructure and the observatory particle detectors themselves, as well as looking for a deployment site (seven candidates) in Europe. There have also been propositions of merging the project with similar international projects, like DUSEL. In June 2011, the LAGUNA collaboration finished the Feasibility Studies of building the proposed neutrino detectors. The studies were paid for by the EU (€1.7 million). No further activity is know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baltic Region
The terms Baltic Sea Region, Baltic Rim countries (or simply the Baltic Rim), and the Baltic Sea countries/states refer to slightly different combinations of countries in the general area surrounding the Baltic Sea, mainly in Northern Europe. The term " Baltic states" refers specifically to one such grouping. Etymology The first to name it the ''Baltic Sea'' ( la, Mare Balticum) was 11th century German chronicler Adam of Bremen. Denotation Depending on the context the ''Baltic Sea Region'' might stand for: * The countries that have shorelines along the Baltic Sea: Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, and Sweden. * The group of countries that are members of the inter-governmental ''Baltic Assembly'' and ''Baltic Council of Ministers'', and generally referred to by the shorthand, Baltic states: Estonia, Latvia, and Lithuania. * Estonia, Latvia, Lithuania and Kaliningrad Oblast of Russia, exclaved from the remainder of Russia.«The Balt ...

Neutrino
A neutrino ( ; denoted by the Greek letter ) is a fermion (an elementary particle with spin of ) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small ('' -ino'') that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles excluding massless particles. The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the strong interaction. Thus, neutrinos typically pass through normal matter unimpeded and undetected. Weak interactions create neutrinos in one of three leptonic flavors: electron neutrinos muon neutrinos (), or tau neutrinos (), in association with the corresponding charged lepton. Although neutrinos were long believed to be massless, it is now known that there are three discrete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutrino Observatory
A neutrino detector is a physics apparatus which is designed to study neutrinos. Because neutrinos only weakly interact with other particles of matter, neutrino detectors must be very large to detect a significant number of neutrinos. Neutrino detectors are often built underground, to isolate the detector from cosmic rays and other background radiation. The field of neutrino astronomy is still very much in its infancy – the only confirmed extraterrestrial sources are the Sun and the supernova 1987A in the nearby Large Magellanic Cloud. Another likely source (three standard deviations) is the blazar TXS 0506+056 about 3.7 billion light years away. Neutrino observatories will "give astronomers fresh eyes with which to study the universe". Various detection methods have been used. Super Kamiokande is a large volume of water surrounded by phototubes that watch for the Cherenkov radiation emitted when an incoming neutrino creates an electron or muon in the water. The Sudbur ...

Antimatter
In modern physics, antimatter is defined as matter composed of the antiparticles (or "partners") of the corresponding particles in "ordinary" matter. Antimatter occurs in natural processes like cosmic ray collisions and some types of radioactive decay, but only a tiny fraction of these have successfully been bound together in experiments to form antiatoms. Minuscule numbers of antiparticles can be generated at particle accelerators; however, total artificial production has been only a few nanograms. No macroscopic amount of antimatter has ever been assembled due to the extreme cost and difficulty of production and handling. Theoretically, a particle and its antiparticle (for example, a proton and an antiproton) have the same mass, but opposite electric charge, and other differences in quantum numbers. A collision between any particle and its anti-particle partner leads to their mutual annihilation, giving rise to various proportions of intense photons (gamma rays), neutrin ...
