Optical injector based on particle acceleration by stimulated emission of radiation in a Penning trap
نویسنده
چکیده
We present results of a 1D analysis demonstrating that electrons oscillating in a Penning trap may drain the energy stored in an adjacent active medium. Consequently, energy imparted by the active medium to the electrons allows them to leave the trap. A simplified configuration is analysed in a self-consistent way and its equilibrium conditions are characterized assuming continuous pumping of the medium.

Electron dynamics in the presence of an active medium incorporated in a Penning trap
A free electron moving in the vicinity of an excited atom may absorb the energy from the bounded electron, this is called collision of the second kind. Contrary to collisions of the first kind where free electrons lose kinetic energy by exciting the atom, in this case, the electron is accelerated and if we assume that all or at least the majority of atoms are excited, then a flow of electrons m...
متن کاملPenning Trap and Vacuum Noise
A number of comments are provided on Rogers's model experiment to measure the circular Unruh vacuum noise by means of a hyperbolic Penning trap inside a microwave cavity. It is suggested that cylindrical Penning traps, being geometrically simpler, and controlled almost at the same level of accuracy as the hyperbolic trap, might be a better choice for such an experiment. Besides, the microwave m...
متن کاملA Penning trap for multiphoton ionization studies in extreme laser fields
We are presently developing a Penning-trap based tool for advanced studies of multiphoton ionization of confined particles and other reactions by highly intense laser light. Particularly, ion manipulation techniques allow control over the particles’ localization and spatial density. It is thereby possible to optimize the laser-particle interaction which is of special importance when laser foci ...
متن کاملExperimental observation of direct particle acceleration by stimulated emission of radiation.
We report the first experimental evidence for direct particle acceleration by stimulated emission of radiation. In the framework of this proof-of-principle experiment, a 45 MeV electron macrobunch was modulated by a high-power CO2 laser and then injected into an excited CO2 gas mixture. The emerging microbunches experienced a 0.15% relative change in the kinetic energy, in a less than 40 cm lon...
متن کاملParticle acceleration by stimulated emission of radiation: theory and experiment.
The interaction of electromagnetic radiation with free electrons in the presence of an active medium has some appealing outcomes. Among them is particle acceleration by stimulated emission of radiation (PASER). In its framework, energy stored in an active medium (microscopic cavities) is transferred directly to an e -beam passing through. We have developed a two-dimensional analytic model for t...
