Biofuels: Ethanol - Separating Fact from Fiction

This fact sheet presents documented information that dispels some of the myths that people have developed about ethanol. Once the facts are revealed, it becomes clear that using and producing ethanol for transportation is good for the country's economy, environment, and energy future.

Geothermal today: 1999 Geothermal Energy Program highlights (Clean energy for the 21st century booklet)

The purpose of this publication is to educate and inform readers about research activities being carried out by the federal Geothermal Energy Program, and its achievements and future goals. This publication should help raise the visibility and awareness of geothermal energy contributions and potential, especially as part of the nation's clean energy technologies portfolio. The message of the publication is that program resources are being well spent and the results are real and tangible. A secondary message is that geothermal energy is a viable generation option with environmental, economic, and other benefits.

SOME PHYSICAL AND ENGINEERING ASPECTS OF HIGH CURRENT EBIS. (open access)

SOME PHYSICAL AND ENGINEERING ASPECTS OF HIGH CURRENT EBIS.

Some applications of an Electron Beam Ion Source (EBIS) require intensities of highly charged ions significantly greater than those which have been achieved in present EBIS sources. For example, the ion source for the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) must be capable of generating 3x10{sup 9} ions of Au{sup 35+} or 2 x 10{sup 9} ions of U{sup 45+} per pulse [1]. In this case, if the fraction of ions of interest is 20% of the total ion space charge, the total extracted charge is {approx}{approx} 5 x 10{sup 11}. It is also desirable to extract these ions in a 10 ps pulse to allow single turn injection into the first synchrotron. Requirements for an EBIS which could meet the needs of the LHC at CERN are similar ({approx} 1.5 x 10{sup 9} ions of Pb{sup 54+} in 5.5 {micro}s). This charge yield is about an order of magnitude greater than that achieved in existing EBIS sources, and is what is meant here by ''high current''. This also implies, then, an EBIS with a high electron beam current. The scope of problems in a high current EBIS is broad, and includes generating a sufficient total …
