Vortex meeting - December 14, 2016

Invitation

Based on your feedback we will meet this Wednesday Dec. 14th at 4pm EDT. We'll meet locally in CEBAF Center F-Wing Rm. 224-225 and by phone/video conference call using BlueJeans (info below). Since the purpose of this meeting is to discuss an upcoming NSF funding opportunity I'd like to take a few minutes at the beginning to set the stage. However, since we haven't met in awhile and there are some new faces joining it would be nice to then go "around the room" to take a few minutes and share recent activities or interest. Afterwards, we can return to discussing how we may consider to organize our OAM interests, and see if some can be refined for a proposal.

Agenda

Summary of a few avenues of research to generate OAM beams at Jefferson Lab

Generation of electron vortex beams

unpolarized electrons by field emission to produce OAM electrons for acceleration e.g. Ben's work at Oregon

spin polarized electrons from photoemission or photo-assisted field emission to produce spin polarized OAM electrons for acceleration

Generation of photon vortex beams

inverse Compton scattering of OAM laser from e- beam @ ~MeV energy (OAM x-ray) or ~GeV => test at CEBAF/LERF (~MeV) or CEBAF C-Compton? (~GeV)

non-linear inverse Compton scattering
