These investigations were carried out with thin foil targets, illuminated by 100 TW laser pulses at the Arcturus laser facility; the polarization measurement is based on the spin dependence of hadronic proton scattering off nuclei in a Silicon target. We find proton beam polarizations consistent with zero magnitude which indicates that for these particular laser-target parameters the particle spins are not aligned by the strong magnetic fields inside the laser-generated plasmas LB - PUB:(DE-HGF)16 UR - <Go to ISI:>//WOS:000332323400068 DO - DOI:10.1063/1.4865096 UR - https://juser.fz-juelich.de/record/151153 ER -
