PESP2008

Workshop on Sources of Polarized Electrons and High Brightness Electron Beams
October 1-3, 2008

Note: SPIN2008 hosted by University of Virginia, Charlottesville, VA, October 6 - 11, 2008

Proceedings Submissions

Dear PESP2008 Contributors,

It's time to start writing your PESP2008 paper. PESP2008 Proceedings will be published as part of the SPIN2008 Proceedings, by the American Institute of Physics (AIP) in print and electronic versions that will be identical. Instructions for authors, templates and other information can be found at http://proceedings.aip.org/proceedings/authors.jsp. We will use the 6 x 9 inch format.

After speaking with Dr. Don Crabb of the University of Virginia and chair of SPIN2008, we think it is best that you send me your paper in original Latex or MS Word file format, along with a pdf version, and I will organize all PESP papers into one file and forward to him. In addition, all authors must complete and sign an AIP Copyright Transfer agreement available at the AIP website. This form would need to be mailed to me via conventional post.

Speakers and poster presenters are allowed 5 pages and the deadline for submission of your paper to me is

December 31, 2008.

For those of you that attended SPIN, your registration fee covers the cost of the PESP/SPIN Proceedings. For those of you that did not attend SPIN, I am working with Don Crabb to determine what the Proceedings will cost you. I apologize for not having considered this detail when setting PESP registration fees. Of course my intention is to make the Proceedings very affordable. Have I forgotten anything? Please don't hesitate to ask questions.

Best regards,
Matt
