Description of the research topic:
According to numerical studies, with dielectric laser accelerators (DLAs) based on a double-grating dielectric structure it is possible to achieve loaded gradients exceeding 1 GeV/m [1]. Very recently, the working of such a miniature accelerator was demonstrated in proof-of- principle experiments [2]. However, these results also show the drawback of this approach: for a laser with about 1 µm wavelength the gap between the dielectric structures can be only a few hundred nm, thereby limiting the charge of the accelerated electron/ion bunch.
For dielectric grating accelerators using THz driving pulses rather than visible/near-infrared ones enables to exploit advantages of the two-to- three orders of magnitude longer wavelength and oscillation period of THz pulses. The PhD student will analyse the THz pulse driven DLA structures.
