Spatial Intensity Gradients of Impulsive Particle Events and Supradiffusive Magnetic Fields
Abstract
The low-energy ion intensity profiles of impulsive solar energetic particle (SEP) events display both sharp (< 2.5 min) local gradients and larger scale ( 1-6 hour) dropouts, indicative of fast crossfield transport on the larger scales in spite of restricted short-scale transport. Rapid variations and modulations within the few-hour long channels of enhanced intensity are also observed. We show that these features are a signature of strong supradiffusion of magnetic field lines in the inner heliosphere.
