Description
Laser Wakefield Acceleration (LWFA) of charge particles (for example: electron beam) has potential to drastically reduce the size of the future particle accelerators. Owing to its compact size, even for GeV class acceleration of particles, LWFA has ability to serve the broad user communities of the next generation of radiation sources based on free-electron-laser (FEL) [1]. *MIRAI project is one of the highly ambitious projects in this category among similar research work at other laboratories in the world. MIRAI project is aiming for multi-stage acceleration of electron beams in LWFA configuration, employing energy slicing and chirp rotation schemes, in order to deliver GeV class electron beams with energy spread below 1%. Later, these electron beams will be synchronized with the micro or conventional undulators for radiation generation.
In this presentation we will show the design concept and present status of the MIRAI project. We will also show the recent progress made in successful demonstration of multi-staging of LWFA with an energy gain close to 100 MeV in the booster stage (second stage) and their preliminary coupling with the undulator.
