## Key findings

- Simulation shows effective wake-field generation with swept laser pulses.
- The scheme enables localized excitation of micro-structure cells.
- Potential for collider applications in near-future accelerator technology.

## Abstract

We describe here the latest results of calculations with FlexPDE code of wake-fields induced by the bunch in micro-structures. These structures, illuminated by swept laser bust, serve for acceleration of charged particles. The basis of the scheme is a fast sweeping device for the laser bunch. After sweeping, the laser bunch has a slope ~45o with respect to the direction of propagation. So the every cell of the microstructure becomes excited locally only for the moment when the particles are there. Self-consistent parameters of collider based on this idea allow consideration this type of collider as a candidate for the near-future accelerator era.
