Compact cryogenic source of periodic hydrogen and argon droplet beams for relativistic laser-plasma generation
Rev. Sci. Instrum., 83 :025102 (February 2012)
Abstract:
We present a cryogenic source of periodic streams of micrometer-sized hydrogen and argon droplets as ideal mass-limited target systems for fundamental intense laser-driven plasma applications. The highly compact design combined with a high temporal and spatial droplet stability makes our injector ideally suited for experiments using state-of-the-art high-power lasers in which a precise synchronization between the laser pulses and the droplets is mandatory. We show this by irradiating argon droplets with multi-terawatt pulses.
