Cím: Micromanaging laser-plasma interactions for fast accelerator science

Absztrakt: Laser plasma accelerators (LPAs) hold great promise as ultra-
compact electron sources because of their high acceleration gradients (~GeV/
cm) and flexible format, but have yet to gain wide-spread acceptance due to
limitations in their tunability and stability. These limitations, caused by
the fluid nature of the accelerator formation, have required the development
of sophisticated new techniques tailored to manage the microscopic dynamics of
the laser-plasma interaction. This talk will highlight recent work aimed at
addressing the unique control challenges of this accelerator format, including
the use of multiple-pulse collisions to trigger electron injection, the use of
tomography to see through walls, the use of spectroscopic imaging to track
gas-plume and laser evolution and the use of chirped-pulse interferometry to
resolve wake-induced Raman shifts. These methods provide a tremendous wealth
of in-situ, shot-by-shot information from within the accelerator, enabling
control of and shining new light on what has previously been a black box
accessible primarily by simulation.
