Abstract
In order to investigate the polarization degree of laser-accelerated \(^3\mathrm{He}\) ions from a polarized \(^3\mathrm{He}\) gas–jet target, several challenges have to be overcome. One of these is the development of an appropriate polarized \(^3\mathrm{He}\) gas–jet target. Since our experiments are carried out at the PHELIX Petawatt Laser Facility, GSI Darmstadt, the layout of the setup has to cope with the available space within the PHELIX target chamber. The essential components of such a layout are a magnetic holding field for storing polarized \(^3\mathrm{He}\) gas inside the vacuum chamber for many hours, the gas–jet source for providing the desired laser target, and finally, a polarimeter for measuring the spin-polarization degree of laser-accelerated \(^3\mathrm{He}^{2+}\) ions.
