Kinetic Imprints of Ion Acceleration in Collisionless Magnetic Reconnection

Fast collisionless magnetic reconnection implies fast energy conversion. The main form of conversion in concerns bulk ion acceleration with resulting jets. Based on theoretical analysis and MMS data, we examine the kinetic imprints context rates. analyze observations include beams toward X-line distorted velocity distributions lead to a bipolar reversal an off-diagonal element pressure tensor across X-line, supporting enhancement ion-scale electric field.
