研究目的
Investigating the concept of a laser-driven plasma accelerator for polarized proton (or deuteron) beams with a kinetic energy up to several GeV.
研究成果
The T-BMT equation, describing the spin precession in electromagnetic fields, has been implemented into the VLPL PIC code to simulate the semi-classical spin motion during laser-plasma interactions. A target containing polarized hydrogen nuclei is needed for producing polarized relativistic proton beams. A corresponding gas-jet target, based on dynamic polarization of HCl molecules, is being built. The ultimate experiment will take place at the 10 PW SULF facility to observe a up to GeV polarized proton beam from laser-generated plasma for the first time.
研究不足
The experimental realization of solid foil targets suitable for laser acceleration with the TNSA mechanism is extremely challenging. Additionally, the Stern–Gerlach effect does not have to be taken into account for further simulation work on proton-spin tracking due to its weak force.
