Laserlab-Europe
LULI - LULI2000/S2001
Three laser beams are available in this experimental area - the ns NORTH beam, the ps SOUTH beam [pico2000 configuration] and the ns blue beam - according to a fixed irradiation geometry. The MILKA target chamber is a spherical vacuum vessel, with a diameter of around 2m. The vacuum inside can be pushed down to 10-2 mbar (10-4 Pa) in 30 minutes. As the SOUTH beam is operated in the ps regime, the room is radioprotected and radiologically controlled thanks to implementation of dosimeters in strategic places.
