LEAR during its first year of operation

Construction of the Low Energy Antiproton Ring (LEAR) had been completed in July 1982, followed by tests with protons and antiprotons on machine properties, acceleration, deceleration and stochastic cooling. At the beginning of 1983, LEAR hardware was brought to operational level, and in July 1983 the first antiprotons were delivered to the experiments. See 8207133 for completion and start-up and 9007366 for a more detailed description. See also 8201061, 8204131.
