International Workshop on Positrons at Jefferson Lab
March 25-27, 2009
Thomas Jefferson National Accelerator Facility
Newport News, VA

Dear JPOS09 Speaker,

     On behalf of the JPOS09 organizing committee, we thank you for creating a successful workshop. All of the presentations are posted to the workshop website and we next look forward to your contribution to the workshop proceedings. The proceedings will, in a practical way, help us construct an extensions of the workshop's primary goal: to assess the motivation and support for positron programs at Jefferson Lab. In particular, we encourage any comments, recommendations or technical perspective aimed at the growth of a positron program at Jefferson Lab, and also the broader relevance to other research and user communities.

     For the proceedings, please use the AIP template (US 6x9 format, Word or Latex, available here: ) to prepare your contribution. The recommended length is 5 pages and should be suitable for black & white printing. The organizers will collect all talks and forward to the AIP. We prefer that you provide a PDF printable version and also all source files for minor layout editing as needed. All files can be sent to Additionally, please download and complete the Transfer of Copyright form. The form can also be sent as a scanned image, otherwise please send to me by post. Last, but not least, we ask for your contribution by Friday, May 1st. If you have any questions please feel free to contact me. Finally, we will use the mailing address provided during registration to deliver your proceedings - if incorrect or changes then please let us know.

Thank you again for your contributions,
Joe Grames on behalf of JPOS09 OC

First Circular

This 3 day workshop plans to explore the case for positron physics at Jefferson Lab, particularly within the context of the laboratory's energy upgrade to 12 GeV, and to discuss technical R&D issues to create and accelerate positrons at CEBAF. The workshop is jointly sponsored by Jefferson Lab, the Idaho Accelerator Center and the Laboratory for Subatomic Physics and Cosmology, Grenoble. The workshop will have sessions on the following topics:

The workshop agenda will be largely composed of invited talks, however, we intend to also solicit speakers with new ideas. In particular, participants interested in presenting ideas for experiments in the context of the high energy 12 GeV CEBAF era or the lower energy applied physics arena are strongly encouraged to contact the organizing committee (
