With its combination of unique large-solid-angle photon and state of the art charged particle detection devices the CFEL-ASG Multi-Purpose (CAMP) instrument is designed to house a broad variety of experiments at x-ray free electron lasers.
The CAMP chamber was recently commissioned at the first X-ray FEL, the LCLS at SLAC. Its capability for correlated measurements of fluorescence, photo diffraction, ion time of flight and ion momentum distribution was examined by the Max Planck Advanced Study Group and then employed during the first two very successful runs using a variety of different targets and detector combinations.
In the particular setup discussed in this talk pnCCDs and time and space resolving spectrometers were grouped around the intersection of the X-FEL beam and a supersonic gas jet to simultaneously collect data on fluorescent photons and recoil ions respectively. Preliminary results for X-ray ionization of rare gases and molecules will be reported.
