Abstract: Nowadays, several thousand accelerators are at work around the world in an extensive area of applications, ranging from industrial processes to scientific discoveries. Indeed, today’s particle accelerators not only address many of the confronting challenges like energy, economy and industry for the worldwide nations, but also serve as a unique tool to probe/search new physics that govern the universe. In this way, the next generation of colliders and in particular CERN, specifically in the AWAKE project, play the most important role for the current and ongoing challenges in high-energy physics experiments.
In this talk, we will have a brief introduction to the AWAKE experiment and specially our contribution alongside where we are designing a new photo-injector with very critical parameters. In this way, first through a detailed beam dynamic study we investigate on time evolution of envelopes and emittance of bunched beams in photo-injectors which in turns leads to a new model for describing the bunch behavior in the electron sources. Finally, we apply our model for the design of an ultra-short bunch photo-injector of the AWAKE experiment and present the simulation results.
