Project X (accelerator)
Project-X is a proposed high-intensity proton accelerator complex which is to be built at the Fermi National Accelerator Laboratory. It is planned to produce beams of different energies up to 8 GeV for precision experiments involving kaons and muons. The complex can also be used to create a high-intensity neutrino beam for neutrino oscillation experiments such as NOνA and the Long Baseline Neutrino Experiment. Project-X will be based on superconducting RF components such as those developed for the International Linear Collider. Immediate plans are for cost-effective Cost-effectiveness analysis (CEA) is a form of economic analysis that compares the relative costs and outcomes (effects) of different courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis, which assigns a monetar ... upgrades in proton luminosity referred to as the Proton Improvement Plan-II.

Proton
A proton is a stable subatomic particle, symbol , H+, or 1H+ with a positive electric charge of +1 ''e'' elementary charge. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). One or more protons are present in the nucleus of every atom. They provide the attractive electrostatic central force which binds the atomic electrons. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol ''Z''). Since each element has a unique number of protons, each element has its own unique atomic number, which determines the number of atomic electrons and consequently the chemical characteristics of the element. The word ''proton'' is Greek for "first", and this name was given to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
