Dual beam setup

Experiments using both beams typically use the long focus south beam combined with the short focus north beam (although other options can be delivered). An example layout is shown – here the south beam accelerates electrons via LWFA, and the north beam generates ions approximately orthogonally via a solid target interaction. Different angles between the laser beams can be requested. This includes co- or counter-propagating beams using an f/2 parabola with a 20mm central hole. These arrangements must be discussed before submission of the proposal.

An example dual beam configuration for Gemini Target Area Three. The south beam generates electrons via a long focus laser incident on a gas target, and the north beam is incident on a solid target, generating ions in an orthogonal geometry.
