On the Way to Micro-accelerators

Published on

Optical scale dielectric structures are promising candidates to realize very compact and possibly low cost particle accelerators. They can sustain high acceleration gradients in the range of GeV/m and hencemany orders of magnitude above what can be realized in conventional radiofrequency accelerators.

In a paper that was recently published in Physics of Plasmas, we present detailed results from numerical investigations QUASAR Aimierding Aimidula has carried our into dielectric asymmetric dual-grating accelerators. This work might open up new avenues for chip-size accelerators for a wide range of applications.
