WebApr 11, 2024 · a mechanism for particle acceleration at the source (interstellar medium (ISM) clouds acting as magnetic mirrors) was proposed by Fermi [ 4 ] and this is now called type II or the second order WebIn the second paper [ 31 ], Fermi proposed acceleration between ‘closing jaws’ in which all reflections are head-on and hence energy‐increasing. This idea is an essential ingredient in the astrophysically most important of the generic mechanisms: diffusive shock acceleration (DSA).

WebFermi acceleration is a process by which particle are accelerated to super thermal energies. Usually, the spectrum of thermal distribution (e.g. Maxwell - Boltzmann, … Fermi acceleration, sometimes referred to as diffusive shock acceleration (a subclass of Fermi acceleration ), is the acceleration that charged particles undergo when being repeatedly reflected, usually by a magnetic mirror (see also Centrifugal mechanism of acceleration). It receives its name from physicist … See more Shock waves typically have moving magnetic inhomogeneities both preceding and following them. Consider the case of a charged particle traveling through the shock wave (from upstream to downstream). If it … See more • Fermi-Ulam model • Fermi glow See more Second order Fermi acceleration relates to the amount of energy gained during the motion of a charged particle in the presence of randomly moving "magnetic mirrors". So, if the magnetic mirror is moving towards the particle, the particle will end up with … See more • David Darling's article on Fermi acceleration • Rieger, Bosch-Ramon and Duffy: Fermi acceleration in astrophysical jets.
