Three Problems: Nuclear Energy, National Defense and International Cooperation

Description: A little more than half a century into the Nuclear Age, we cannot look back on a peaceful period, but we can say that the second (nuclear) half of the century has seen much less violence than the first half with its two violent wars. Also the second half of the century has seen the fortunate ending of the Cold War. But as to the future, we are left with three great questions. (1) How can the world be provided with ample energy? (2) How can we avoid the potentially devastating sudden application… more

Advanced, Environmentally Friendly Hydroelectric Turbines for the Restoration of Fish and Water Quality

Description: Hydroelectric power contributes about 10 percent of the electrical energy generated in the United States, and nearly 20 percent of the world�s electrical energy. The contribution of hydroelectric generation has declined in recent years, often as a consequence of environmental concerns centering around (1) restriction of upstream and downstream fish passage by the dam, and (2) alteration of water quality and river flows by the impoundment. The Advanced Hydropower Turbine System (AHTS) Program of… more

Status of the BNL High Current EBIS Test Stand.

Description: As part of a new, compact heavy ion injector for AGS/RHIC complex at Brookhaven National Laboratory we are developing an Electron Beam Ion Source (EBIS) that would satisfy present and future requirements. Such a source should be capable of producing intensities of e.g. Al{sup 35+} ions of about 3 x 10{sup 9} particles/pulse or U{sup 45+} of about 2 x 10{sup 9} particles/pulse. To achieve this, the required e-beam intensity is 10A, at a pulse length of 100ms. An EBIS test stand has been construc… more

Increasing the Space Charge Limit and Other Effects of Cesium Seeding in Hydrogen Negative Ion Sources

Description: The role of cesium seeding in increasing the negative ion current in volume sources is described. By a reduction in the local plasma potential the current of extracted electrons is vastly reduced. As a result, cesium increases the fraction of the transverse space charge limit available to the ions by as much as a factor of three. In addition, cesium can increase the total space charge limit by injection of Cs+ into the presheath-a newly recognized phenomenon consistent with experimental measure… more

Effect of Cesium and Xenon Seeding in Negative Hydrogen Ion Sources

Description: It is well known that cesium seeding in volume hydrogen negative ion sources leads to a large reduction of the extracted electron current and in some cases to the enhancement of the negative ion current. The cooling of the electrons due to the addition of this heavy impurity was proposed as a possible cause of the mentioned observations. In order to verify this assumption, the authors seeded the hydrogen plasma with xenon, which has an atomic weight almost equal to that of cesium. The plasma pr… more
