The A. W. Wright Nuclear Structure Laboratory at Yale University, which houses the first Emperor Van de Graaff accelerator, is being dedicated this month. Its two‐stage tandem machine produces the most energetic protons yet obtained with an electrostatic accelerator—23.50 MeV; this energy could eventually go as high as 30 MeV, according to D. Allan Bromley, director of the laboratory. Beam currents are also high. During acceptance tests in July the Emperor put out 25 microamperes at 15 Mev and 10 μA at 20 MeV.
