PHELIX Target Chamber
Behind the Pulse Compressor, a 45 degrees off-axis copper parabola focuses the
laser beam into the target chamber. This way intensities of more than
1020 W/cm² can be achieved.
The target chamber allows for laser-only experiments. The focusing parabula is
located in the very left vacuum vessel

Experiments carried out so far include the collimation of laseraccelerated particles using
pulsed dipoles as well as the generationof both coherent (X-ray laser) and non-coherent
(k-alpha) secondarysources for supporting the GSI research program.
