1Single-shot electrons and protons time-resolved detection from high-intensity laser–solid matter interactions at SPARC LAB显示文摘Laser–plasma interactions have been studied in detail over the past twenty years,as they show great potential for the next generation of particle accelerators.The interaction between an ultra-intense laser and a solid-state target produces a huge amount of particles:electrons and photons(X-rays andγ-rays)at early stages of the process,with protons and ions following them.At SPARC LAB Test Facility we have set up two diagnostic lines to perform simultaneous temporally resolved measurements on both electrons and protons.F.Bisesto M.Galletti M.P.Anania M.Ferrario R.Pompili M.Botton A.Zigler F.Consoli M.Salvadori P.Andreoli C.Verona 2019High Power Laser Science and Engineering2019,7,3:0
2Density measurements of laser interaction with ordered structured ‘snow' targets显示文摘This paper presents a new method to control the position of a micro-column snow target. This target enables the measurement of the mean electron density of the pre-plasma created by a pre-pulse with different time delays. This research will allow a better understanding of the generation of fast protons from the interaction between a structured pre-plasma and a high intensity laser.E.Schleifer M.Botton E.Nahum S.Eisenman A.Zigler Z.Henis 2014High Power Laser Science and Engineering2014,2,2:0
3Femtosecond laser-induced damage threshold in snow micro-structured targets显示文摘Enhanced acceleration of protons to high energy by relatively modest high power ultra-short laser pulses, interacting with snow micro-structured targets was recently proposed. A notably increased proton energy was attributed to a combination of several mechanisms such as localized enhancement of the laser field intensity near the tip of 1 μm size whisker and increase in the hot electron concentration near the tip. Moreover, the use of mass-limited target prevents undesirable spread of absorbed laser energy out of the interaction zone. With increasing laser intensity a Coulomb explosion of the positively charged whisker will occur. All these mechanisms are functions of the local density profile and strongly depend on the laser pre-pulse structure. To clarify the effect of the pre-pulse on the state of the snow micro-structured target at the time of interaction with the main pulse, we measured the optical damage threshold(ODT) of the snow targets. ODT of 0.4 J/cm^2 was measured by irradiating snow micro-structured targets with 50 fs duration pulses of Ti:Sapphire laser.O.Shavit Y.Ferber J.Papeer E.Schleifer M.Botton A.Zigler Z.Henis 2018High Power Laser Science and Engineering2018,6,1:0
