27th International Electric Propulsion Conference

Pasadena, California October 14-19, 2001

WelcomeWelcome to the 2001 IEPC Proceedings on CD-ROM.This disc is designed so that you may rapidly locate papers by full text search as well as by subject area or paper title.

All papers were submitted as electronic files or images scanned from hard copy and converted to Adobe Acrobat PDF file format for cross-platform access. Since some of the papers were scanned from hardcopy, the viewing quality will vary with the size and quality of fonts used. Even though the viewing quality on your monitor may vary, all papers print clearly.

The materials have been created for viewing with Adobe Acrobat Reader and Full-text Search 5.0, which has been provided on the CD for your use.

Thank You and Enjoy

Chairman’s Remarks

On behalf of the 2001 IEPC organizing committee and the Electric Rocket Propulsion Society, I would like to thank all of the participants for making the 27th International Electric Propulsion Conference one of the most successful ever. The theme of this year’s conference was “Electric Propulsion 2001: Turning Science Fiction into Reality.” We have long dreamed of opening the space frontiers with electrically propelled spacecraft, and in the last few years our community has seen tremendous growth in the use of electric propulsion technologies. This growth is reflected in the attendance at this year’s IEPC, which exceeded 270 registered participants. We had representatives of the electric propulsion communities from 18 different countries and 84 different organizations, including 41 universities. The technical program consisted of 228 technical papers and 19 poster presentations. The social program was equally vigorous, with receptions at the Sheraton Hotel and Huntington Library and banquets at the Hilton and Ritz-Carlton Hotels. Attendees at the conference banquet consumed the equivalent of over a bottle of wine per person on average! This greatly facilitated technical discussions, but may have somewhat reduced the fidelity of the information exchanged during the banquet. We look forward to an equally successful meeting in 2003 at the 28th International Electric Propulsion Conference, which will be held March 17-21 in Toulouse, France.

First Announcement for the28TH INTERNATIONAL ELECTRIC PROPULSION CONFERENCE

March 17-21, 2003, Toulouse, France

STENTOR launch 2002 : flight qualification of Hall thrusters for European geostationary telecommunication satellites

The conference : This conference will be the meeting point for the large community of specialists involved in electric propulsion, from basic research up to industrial development and flight applications. Papers will be solicited on the following topics :

-Electric propulsion systems-Thruster developments-Advanced propulsion concepts-Propulsion components-Spacecraft / thruster interactions-Applications to new missions-In-flight experience-Ground testing-Overview of current programs

The conference site: The conference will be held at the Toulouse Congress Center. Many research centers and industries involved in space technology are located in Toulouse, including CNES, Alcatel Space, ASTRIUM, ONERA and CNRS. This is why Toulouse is considered as the French capital for aerospace. But Toulouse is also famous for gastronomy and quality of life. It is located in the South-West of France, close to the Mediterranean sea and the Pyrénées mountains.

Getting StartedSEARCHINGThe fundamental power of this CD comes from the use of PDF and the high speed search capabilities. These search capabilities enable you to quickly find all the information that is relevant to your needs. Two types of search are possible with Acrobat: 1. FindFind opens a dialog box that allows searching for a character string within the currently open document. Find is relatively slow - Acrobat has to search through the whole document2. Full-text search. This search tool, installed with Acrobat Reader, supports Boolean Full-text search of the complete set of PDF files on the CD. Full-text search is extremely fast - it uses pre-built indexes of all words on the CD, including words that it can recognize within graphs and figures.

Getting StartedFind

To start Find click on the icon in the Acrobat toolbar.This will open the dialog box below:

Simply enter the characters that you are looking for, within the current document, and Acrobat will find them for you.

Getting StartedFull-text searchTo start the Full-text search click on the icon in the Acrobat toolbar.

IndexesWhen you open the Welcome.pdf file you automatically attach a Full-text Search index for all documents in the CD into your Acrobat environment.This is fine for most purposes. However, if you wish to search within other Indexes for other CDs or Acrobat Help, then another Index is attached to Acrobat Reader.This can cause complications of peculiar results because Acrobat does notremove indexes from the search criteria automatically.To eliminate this problem remove the unwanted index from the search criteria by clicking the indexes button within the Acrobat Search.

Getting StartedSetting Search Preferences

It is recommended thatyou set the Edit>Preferences>General>Search as shown:This will allow you to search within the textof the documents and titles and show the maximum set of results.

Tip: When searching enteran * in the title box to get aresults list of all filesin the CD.

Frequently Asked QuestionsQ. How can I eliminate Japanese Font Missing errors, when opening some papers, that

were created with Japanese Microsoft Word.A. Install the Japanese Font package included in a Install sub-directory on this CD.

Q. Why can I NOT perform Full-text search on the CD?A. Probably because you do not have Acrobat Reader with Search installed. You may download it from Adobe’s Web side or install the Windows version from this CD. Make sure that it is the Acrobat version with Search.

Q. Why can I open a paper, yet not find some of it’s textual content as a result of a full text search or Find?A. Most probably because the paper did not use Type 1 fonts, and the text only exists as a bitmap, which can not be indexed or searched.

Q. What is the difference between Find and Full Text Search?A. Find allows you to search within a document and is relatively slow. Full Text Search is very fast and uses a pre-built index of ALL the words in ALL the PDF files on the CD.

Q. Why do I get an error on opening a PDF file, and why does it look as if there is missing data or pictures?A. Most probably because you are using an earlier version of Acrobat. Install the Windows version from this CD or download other OS versions of Reader with Search from the Adobe Website.
