ASACUSA
Atomic Spectroscopy and Collisions Using Slow Antiprotons (ASACUSA), AD-3, is an experiment at the Antiproton Decelerator, Antiproton Decelerator (AD) at CERN. The experiment was proposed in 1997, started collecting data in 2002 by using the antiprotons beams from the AD, and will continue in future under the AD and Antiproton Decelerator, ELENA decelerator facility. ASACUSA physics ASACUSA collaboration is testing for CPT-symmetry by laser spectroscopy of antiprotonic helium and microwave spectroscopy of the hyperfine structure of antihydrogen. It compares matter and antimatter using antihydrogen and antiprotonic helium and looks into matter-antimatter collisions. It also measures atomic and nuclear Cross section (physics), cross-sections of antiprotons on various targets at extremely low energies. In 2020 ASACUSA in collaboration with the Paul Scherrer Institute, Paul Scherrer Institut (PSI) reported spectral measurements of long lived Antiprotonic helium#Pionic helium, pion ...

Antiproton Decelerator
The Antiproton Decelerator (AD) is a storage ring at the CERN laboratory near Geneva. It was built from the Antiproton Collector (AC) to be a successor to the Low Energy Antiproton Ring (LEAR) and started operation in the year 2000. Antiprotons are created by impinging a proton beam from the Proton Synchrotron on a metal target. The AD decelerates the resultant antiprotons to an energy of 5.3 MeV, which are then ejected to one of several connected experiments. The major goals of experiments at AD are to spectroscopically observe the antihydrogen and to study the effects of gravity on antimatter. Though each experiment at AD has varied aims ranging from testing antimatter for cancer therapy to CPT symmetry and antigravity research. History From 1982 to 1996, CERN operated the Low Energy Antiproton Ring (LEAR), through which several experiments with slow-moving antiprotons were carried out. During the end stages of LEAR, the physics community involved in those antimatter ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiprotonic Helium
Antiprotonic helium is a three-body atom composed of an antiproton and an electron orbiting around a helium nucleus. It is thus made partly of matter, and partly of antimatter. The atom is electrically neutral, since both electrons and antiprotons each have a charge of −1, whereas helium nuclei have a charge of +2. It has the longest lifetime of any experimentally producible matter-antimatter bound state. Production These exotic atoms can be produced by simply mixing antiprotons with ordinary helium gas; the antiproton spontaneously removes one of the two electrons contained in a normal helium atom in a chemical reaction, and then begins to orbit the helium nucleus in the electron's place. This will happen in the case of approximately 3% of the antiprotons introduced to the helium gas. The antiproton's orbit, which has a large principal quantum number and angular momentum quantum number of around 38, lies far away from the surface of the helium nucleus. The antiproton can ...

University Of Brescia
The University of Brescia ( it, Università degli Studi di Brescia) is an Italian public research university located in Brescia, Italy. It was founded in 1982 and is branched in 4 Faculties. The University of Brescia was officially established in 1982 with three Schools: Medicine and Surgery, Engineering, Economics and Business. However, the creation phase lasted nearly two decades, so the first attempts to open university courses in Brescia go back to the 1960s. History A first initiative came from Ethan Doro, which opened negotiations in the early 1960s to set up a two-year course in Engineering as a branch of Politecnico di Milano. The excessive financial requirements caused the project to lapse. After this first attempt, the creation of the future Schools of Brescia moved along two distinct paths, one concerning the School of Economics, the other those of Engineering and Medicine. In the field of economic studies, in 1964 a School of Industrial Administration was created, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hiroshima University
is a Japanese national university located in Higashihiroshima and Hiroshima, Japan. Established in 1929, it was chartered as a university in 1949 following the merge of a number of national educational institutions. History Under the National School Establishment Law, Hiroshima University was established on May 31, 1949. After World War II, the school system in Japan was entirely reformed and each of the institutions of higher education under the pre-war system was reorganized. As a general rule, one national university was established in each prefecture, and Hiroshima University became a national university under the new system by combining the pre-war higher educational institutions in Hiroshima Prefecture. The following eight schools were integrated or merged into Hiroshima University under the new system of education. * * - also translated "Hiroshima School of Secondary Education" * - also translated "Hiroshima Women's School of Secondary Education" * * - also trans ...

Oxygen-free Copper
Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below. Specification Oxygen-free copper is typically specified according to the ASTM/ UNS database. The UNS database includes many different compositions of high conductivity electrical copper. Of these, three are widely used and two are considered oxygen-free: * C10100 – also known as ''oxygen-free electronic'' (OFE). This is a 99.99% pure copper with 0.0005% oxygen content. It achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment. Silver (Ag) is considered an impurity in the OFE chemical specification. This is also the most expensive of the three grades listed here. * C10200 – also known as ''oxygen-free'' (OF). While OF is considered oxygen-free, its conductivity rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
