Descrizione
The relativistic interaction of short pulsed lasers or electrons with plasma has recently led to the birth of a new generation of femtosecond X-ray sources. Radiations with properties similar to those that can be observed from a wiggler or undulator, can be generated by the oscillations induced in the excited plasma by electrons (PWFA) or by lasers (LWFA), making plasma an interesting medium both for the acceleration as well as for the radiation source, with properties of being compact, providing collimated, incoherent, femtosecond radiation. Thus, a lot of effort is being made to understand and improve this new source to make it really competitive, in this poster is summarizes and shown some numerical results of a simplified model called plasma ion column, highlighting strenghts, limitation ans scaling laws which allow for a comparison with other types of more consolidated sources of light.
