Description
One core challenge of the SPARTA project [1] is to offer achromatic staging of plasma accelerators to reach high energies. We propose to achieve this through a specific lattice design, made of dipoles in combination with a novel concept: nonlinear active plasma lenses [2]. Originally motivated by an article on the Hall effect in a glow discharge [3], our idea is to shape the plasma lens discharge B-field distribution with an additional external magnet. The device is developed and manufactured at the University of Oslo. Its B-field currently is being characterised at CLEAR test facility, in combination with plasma hydrodynamic simulations in collaboration with DESY.
