Proceedings Information

Dear JPos17 Contributor,

Proceedings of the International Workshop on Physics with Positrons at Jefferson Lab (JPos17) will be published by the American Institute of Physics (AIP), and will be available in perpetuity for free.   Workshop proceedings will be accepted for both the oral and poster presentations. Authors must submit two documents: 1) a high quality PDF version of their proceedings and a 2) copyright license agreement form. Instructions and templates in both Word and Latex formats are available from the AIP Scitation website:

A page length of 5 pages is recommended, but we ask all authors not to exceed 8 pages.  Both the documents (PDF and copyright) should be uploaded no later than Friday, November 17, 2017 to the Indico program corresponding to your presentation:

We encourage authors to consider the following factors:

  • Motivate the impact of polarized or unpolarized positrons for the physics case being considered,
  • Propose experimental measurements that include projected kinematics, achievable statistical precision or figure of merit,
  • Define the positron and/or electron beam parameters (e.g. beam size, energy spread) required for your experiment to be successful,
  • Identify experimental technical challenges (e.g. hardware, software), and
  • Do not refrain from addressing manpower, support, or funding as is relevant for making the case.


Please do not hesitate to contact us if you have questions.

On behalf of the JPos17 Organizing Committee,

Joe Grames and Eric Voutier
Co-Chairs, JPos17

Remote Participation

JPos17 will be available to remote participants using the BlueJeans video-conferencing system.

The meeting ID 607904245 will be available daily from TUE Sep 12 - FRI Sep 15 between 0800-1800 EDT locally.

We will support Desktop Sharing and Audio (remote participants are asked to MUTE their microphones when not speaking)

Registration for the Workshop on Physics with Positrons at Jefferson Lab is now open.

Abstract Submission deadline is extended to September 1, 2017.

We are now only accepting abstracts for invited oral or contributed poster presentations.

This workshop is organized to explore the complementary physics potential offered by a polarized positron beam at JLab.  We seek presentations and discussions of the application of positron beams in the context of CEBAF 12 GeV, a possible Positron-Ion collider (complementary to an Electron-Ion Collider), and an eventual low-energy positron facility.

The physics potential will be evaluated on the basis of beam intensity and polarization. At CEBAF 12 GeV, beam intensities about 10-100 nA CW and >60% polarization are expected, at EIC energies a luminosity of 10^33 cm-2/s and >40% polarization are considered and at low energies positron beams with a flux about 10^10 e+/s with >50% polarization are likely. Workshop proceedings are intended to inform a White Paper for a positron physics program at JLab.

The workshop is organized in plenary and parallel sessions according to the topics:

- Interference physics (J. Arrington & C. Hyde, conveners)
- Charged current physics (Y. Furletova & W. Melnitchouk, conveners)
- Test of the Standard Model (M. Battaglieri & X. Zheng, conveners)
- Positron applications (T. Forest & F. Selim & B. Vlahovic, conveners)
- Positron source and beam physics (J. Grames & V. Morozov, conveners)

The program will be composed of both invited and contributed talks, and will comprise also a poster session. Student support is available to encourage their participation in the workshop.

Registration Announcement

Registration is now open.


This 4 day workshop plans to explore the scientific basis for polarized and unpolarized positron beams at JLab in the context of 12 GeV CEBAF, the proposed Jefferson Lab Electron Ion Collider (JLEIC), and also for low energy applications. An accelerator session dedicated to positron production and beam formation for each scenario completes the scientific program.   Collecting the motivation and requirements for a positron physics experimental program within the workshop proceedings as a basis for a Jefferson Lab Positron Physics white paper is a key goal of the meeting.  The workshop will cover the following topics:

  • Multi-photon exchange
  • Deeply virtual Compton scattering
  • Electroweak structure of hadrons
  • Heavy quark production
  • Beyond the Standard Model physics
  • Low energy polarized positron beam applications
  • Polarized electron and positron sources
  • Multi-turn accumulation and fast kickers
  • Positron beams at CEBAF, JLEIC and LERF

The workshop agenda will be composed of plenary sessions with both invited talks steered by an international organizing committee and contributed talks.  A reception and networking/poster session are also planned.  Students are especially encouraged to contribute to the workshop poster session.  Those interested in presenting at the workshop are encouraged to contact the organizing committee

The workshop is jointly supported by Jefferson Lab, Jefferson Science Associates and IPN Orsay.
