Chromospheric magnetic field and density structure measurements using hard X-rays in a flaring coronal loop
E. P. Kontar, I. G. Hannah, A. L. MacKinnon
A novel method of using hard X-rays as a diagnostic for chromospheric density and magnetic structures is developed to infer sub-arcsecond vertical variation of magnetic flux tube s…
Particle acceleration by fluctuating electric fields at a magnetic field null point
P. Petkaki, A. L. MacKinnon
Particle acceleration consequences from fluctuating electric fields superposed on an X-type magnetic field in collisionless solar plasma are studied. Such a system is chosen to mim…
Regularized energy-dependent solar flare hard x-ray spectral index
Eduard P. Kontar, Alexander L. MacKinnon
The deduction from solar flare X-ray photon spectroscopic data of the energy dependent model-independent spectral index is considered as an inverse problem. Using the well develope…
Fast electron slowing-down and diffusion in a high temperature coronal X-ray source
Ross K. Galloway, Alexander L. MacKinnon, Eduard P. Kontar +1
Finite thermal velocity modifications to electron slowing-down rates may be important for the deduction of solar flare total electron energy. Here we treat both slowing-down and ve…
