1960s vintage 2MeV “High Voltage” vandergraff linear accelerator. <\/figcaption><\/figure>\n<\/figure>\n\n\n\n According to the Inverse scattering problem<\/a>, any mechanism by which a particle produces radiation (where kinetic energy<\/a> of the particle is transferred to the electromagnetic field<\/a>), can be inverted such that the same radiation mechanism leads to the acceleration of the particle (energy of the radiation field is transferred to kinetic energy of the particle). The opposite is also true, any acceleration mechanism can be inverted to deposit the energy of the particle into a decelerating field, like in a kinetic energy recovery system<\/a>. This is the idea enabling an energy recovery linac<\/a>. This principle, which is also behind the plasma or dielectric wakefield accelerrators, led to a few other interesting developments in advanced accelerator concepts:<\/p>\n\n\n\n

\n\n\n\nAt present the highest energy accelerators are all circular colliders, but both hadron accelerators and electron accelerators are running into limits. Higher energy hadron and ion cyclic accelerators will require accelerator tunnels of larger physical size due to the increased beam rigidity<\/a>.<\/p>\n\n\n\n
For cyclic electron accelerators, a limit on practical bend radius is placed by synchrotron radiation losses and the next generation will probably be linear accelerators 10 times the current length. An example of such a next generation electron accelerator is the proposed 40 km long International Linear Collider<\/a>.<\/p>\n\n\n\n
It is believed that plasma wakefield acceleration<\/a> in the form of electron-beam “afterburners” and standalone laser pulsers might be able to provide dramatic increases in efficiency over RF accelerators within two to three decades. In plasma wakefield accelerators, the beam cavity is filled with a plasma (rather than vacuum). A short pulse of electrons or laser light either constitutes or immediately precedes the particles that are being accelerated. The pulse disrupts the plasma, causing the charged particles in the plasma to integrate into and move toward the rear of the bunch of particles that are being accelerated. This process transfers energy to the particle bunch, accelerating it further, and continues as long as the pulse is coherent.[38]<\/a><\/sup><\/p>\n","protected":false},"excerpt":{"rendered":"
