CLAS Detector

	CLAS Detector CEBAF Large Acceptance Spectrometer (CLAS) is a nuclear and particle physics detector located in the experimental Hall B at Jefferson Laboratory in Newport News, Virginia, United States. It is used to study the properties of the nuclear matter by the collaboration of over 200 physicists (CLAS Collaboration) from many countries all around the world. The 0.5 to 12.0 GeV electron beam from the accelerator of Jefferson Laboratory is brought into "Hall B", the experimental hall that houses the CLAS system. Electrons or photons in the incoming beam collide with the nuclei of atoms in the physics "target" located at the center of CLAS. These collisions generally produce new particles, often after the target nucleons (protons and neutrons) are briefly excited to heavier-mass versions of the familiar protons and neutrons. A whole variety of intermediate-mass short-lived particles called "mesons" can be created. Scattered electron as well as the longer-lived produced particles travel through t ...

	Jefferson Lab Thomas Jefferson National Accelerator Facility (TJNAF), commonly called Jefferson Lab or JLab, is a US National Laboratory located in Newport News, Virginia. Its stated mission is "to provide forefront scientific facilities, opportunities and leadership essential for discovering the fundamental structure of nuclear matter; to partner in industry to apply its advanced technology; and to serve the nation and its communities through education and public outreach." Since June 1, 2006, it has been operated by Jefferson Science Associates, LLC, a limited liability company created by Southeastern Universities Research Association and PAE Applied Technologies. Until 1996 it was known as the Continuous Electron Beam Accelerator Facility (CEBAF); commonly, this name is still used for the main accelerator. Founded in 1984, Jefferson Lab employs more than 750 people, and more than 2,000 scientists from around the world have conducted research using the facility. History The facility w ...

picture info	Newport News, Virginia Newport News () is an independent city in the U.S. state of Virginia. At the 2020 census, the population was 186,247. Located in the Hampton Roads region, it is the 5th most populous city in Virginia and 140th most populous city in the United States. Newport News is included in the Hampton Roads metropolitan area. It is at the southeastern end of the Virginia Peninsula, on the northern shore of the James River extending southeast from Skiffe's Creek along many miles of waterfront to the river's mouth at Newport News Point on the harbor of Hampton Roads. The area now known as Newport News was once a part of Warwick County. Warwick County was one of the eight original shires of Virginia, formed by the House of Burgesses in the British Colony of Virginia by order of King Charles I in 1634. In 1881, fifteen years of rapid development began under the leadership of Collis P. Huntington, whose new Peninsula Extension of the Chesapeake and Ohio Railway from Richmond opene ...
