Simulations of HXR Foot-point Source Sizes for Modified Thick-target Models
Abstract
We study vertical sizes of foot-point hard X-ray (HXR) sources using a relativistic test particle approach in a flare loop with a converging magnetic field. We compare results for the Collisional Thick Target Model (CTTM) with recently proposed modifications of the CTTM comprising a secondary acceleration of beam electrons. Our preliminary results indicate that none of the proposed modifications of the CTTM can explain the observed sizes of the HXR sources in a single loop flare scenario.
