Complementarity of Laboratory and Space Experiments on Reconnexion

Reconnection research has for some time been focused upon understanding the electron scale physics in the electron diffusion region (EDR), both in space and in the laboratory. Ren et al. [2008 PRL] reported identification and resolution of the EDR in the MRX laboratory experiment. More recently, Burch et al. [2016] reported identification of the EDR in reconnection at the magnetopause. Space observations from MMS have also provided the first capability to resolve and measure the full electron VDF within and around the EDR, making it possible to observe electron acceleration by the reconnection electric field and revealing new features of the EDR. Laboratory and space explorations of EDR physics may complement and inspire each other in other ways to be discussed by the panel.
