Abstract
Hot electrons injected during solar flares at the top of coronal loops interact with the cooler chromospheric plasma and excite lower hybrid (LH) instabilty. The saturation electric fields due to LH instability can be of the order of a few hundred V cm(-1). Such high electric fie lds can stochastically accelerate protons and other minor ions. The he avier ions are preferentially accelerated by this stochastic process.
