X rays emerge when the electrons, accelerated by a strong electric field, slam into a tungsten target. Why is that electrons radiate electromagnetic energy when they are accelerated? In this model the gamma rays are emitted as synchrotron radiation by electrons that are accelerated to much lower energies. A sufficiently strong electric field can further accelerate these electrons. These electrons accelerate in the electric field of the wake. This action causes the solar atmosphere to sizzle with high-energy X-rays and gamma rays and accelerate proton and electron particles into the solar system. In a strong electric field, free electrons can be accelerated onto its inner surface. The synchrotron can accelerate electrons from a mere walking pace up to almost the speed of light. According to Al Smith, much current research is focused on the use of lasers to accelerate protons, rather than using existing cyclotron and synchrotron sources. These electrons are further accelerated to strike a fluorescent screen, where the effects can easily be seen by the eyes. These electrons are then accelerated by a static electric field towards a fluorescent screen. Origin Early 16th century (in the sense ‘hasten the occurrence of’): from Latin accelerat- ‘hastened’, from the verb accelerare, from ad- ‘towards’ + celer ‘swift’.
