The Extreme Light Infrastructure – Attosecond Light Pulse Source (ELI-ALPS), the Hungarian pillar of ELI ERIC1, is the first of its kind that operates by the principle of a user facility, supporting laser based fundamental and applied researches in physical, biological, chemical, medical and materials sciences at extreme short time scales. This goal is realized by the combination of specialized primary lasers which drive nonlinear frequency conversion and acceleration processes in more than twelve different secondary sources. Thus a uniquely broad spectral range of the highest power and shortest light pulses becomes available for the study of dynamic processes on the attosecond time scale in atoms, molecules, condensed matter and plasmas2-3. The attosecond secondary sources are based on advanced techniques of Higher-order Harmonic Generation (HHG)4-5. Other secondary sources provide THz radiation or particle beams for plasma physics and radiobiology. A set of state-of-the-art endstations will be accessible to those users who do not have access or do not wish to bring along their own equipment. At the current phase of the project ELI-ALPS welcomes the submission of proposals6 for scientific experiments that will support the ramping up of the broad selection of light sources and experimental stations available. ELI-ALPS provides beamtime as well as technical and scientific support for the experiments.
