Laser-driven ion acceleration in plasmas — •Jörg Schreiber — Ludwig-Maximilians-Universität München, Garching b. München

We investigate acceleration of ion bunches during relativistically intense laser pulse interactions with plasmas. Relying on coherent acceleration, such sources feature distinct ion bunch characteristics, including (ultra)short bunch duration, high bunch density, low emittance and synchronism with other parallel laser-driven sources. I review the main acceleration concepts based on our recent studies with various target (plasma) types; including ultrathin foils and levitated micro targets. For applications in fields of radiation physics, chemistry, biology and medicine, we have established the Centre for Advanced Laser Applications (CALA). CALA will feature the ATLAS3000 chirped pulse amplification system that delivers driving laser pulses with peak power of 3 petawatts. Advancing towards an integrated laser-driven ion accelerator system (ILDIAS) represents a remarkable technological challenge. In this talk, I present our experiences in target technology, ion beam guidance and instrumentation. Among the numerous potential applications of laser-driven particle acceleration [1], ion-bunch induced ultrasound waves in water is highlighted as a fascinating example at the interface of tailored detection methodology and physics at high local and instantaneous energy density.
