Query: The role of three-dimensional transport in driving enhanced electron
  acceleration during magnetic reconnection   Magnetic reconnection is an important driver of energetic particles in many
astrophysical phenomena. Using kinetic particle-in-cell (PIC) simulations, we
explore the impact of three-dimensional reconnection dynamics on the efficiency
of particle acceleration. In two-dimensional systems, Alfv\'enic outflows expel
energetic electrons into flux ropes where they become trapped and disconnected
from acceleration regions. However, in three-dimensional systems these flux
ropes develop axial structure that enables particles to leak out and return to
acceleration regions. This requires a finite guide field so that particles may
move quickly along the flux rope axis. We show that greatest energetic electron
production occurs when the guide field is of the same order as the reconnecting
component: large enough to facilitate strong transport, but not so large as to
throttle the dominant Fermi mechanism responsible for efficient electron
acceleration. This suggests a natural explanation for the envelope of electron
acceleration during the impulsive phase of eruptive flares.
