ASG Hamburg

The ASG Hamburg, based at the Center for Free Electron Laser Science (CFEL) at DESY in Hamburg, ties together and supports the activities of the participating Max Planck Institutes at FEL facilities worldwide. Currently, these are the Free Electron Laser in Hamburg (FLASH), the Linac Coherent Light Source (LCLS) in the USA, and the SPring 8 Compact SASE Source (SCSS) (SCSS) in Japan, where experiments ranging from atomic and molecular physics, chemistry, biophysics and biology are performed in collaboration with international research teams.
In addition, the ASG Hamburg runs a femtosecond laser and an x-ray laser-plasma source, which are used for the preparation of FEL experiments and for independent research projects.

The CFEL-ASG Multi-Purpose chamber (CAMP) was especially designed for accomodating unique large-area, single-photon counting pnCCD detectors, developed by the Max Planck Semiconductor Laboratory in Munich, together with advanced many-particle ion and electron imaging spectrometers (reaction microscope, REMI; velocity map imaging, VMI). Moreover, various types of atomic, molecular, and cluster jets as well as particle injectors can be implemented, short-pulse or nanosecond lasers can be fed in for pump-probe measurements or for laser-aligning molecules, and solid-state targets can be mounted. The CAMP chamber will be used for photon-particle coincidence and diffractive imaging experiments at FLASH and LCLS.
