abstract = "We present in situ observation of double layer (DL) and associated
electron measurement in the subspin time resolution in the
separatrix region during reconnection for the first time. The DL
is inferred to propagate away from the X line at a velocity of
about ion acoustic speed and the parallel electric field carried
by the DL can reach -20 mV/m. The electron displays a beam
distribution inside the DL and streams toward the X line with a
local electron Alfv{\'e}n velocity. A series of electron holes
moving toward the X line are observed in the wake of the DL. The
identification of multiple similar DLs indicates that they are
persistently produced and therefore might play an important role
in energy conversion during reconnection. The observation suggests
that energy dissipation during reconnection can occur in any
region where the DL can reach. © 2014. American Geophysical Union.
