It is planned that the Short-Pulsed Particle and Radiation Center at the Forschungszentrum Jülich (JuSPARC) will become an interdisciplinary center for collaborative research using ultra-short pulsed photons as well as neutrons and polarized ion beams. These beams will be generated employing the radiation from a high-power, short-pulse laser (power above 1 PW at pulse durations in the 10 fs range), using nonlinear upconversion in the case of photons or novel target technologies in the case of particles.

An intense light pulse (yellow-orange) produces a plasma wave (white, modulated surface) from oscillating electrons and stationary helium ions. Some electrons leave the plasma wave and fly close to the speed of light as a swarm (red spheres) behind the laser pulse

Temporally structured photon, electron, neutron and proton beams can be applied to probe such phenomena as the study of time-dependent phenomena related to electron and hadron spin excitation processes on ultra-short time scales or to gain access to the broad field of highly nonlinear phenomena, which often require a subtle combination of driver stimulus and probe to yield quantitative insight. In particular, short-pulse lasers are of central importance in providing a route to a whole new generation of dynamics experiments down to the attosecond timescale and are able to create extremely strong electromagnetic field gradients needed for the investigation of nonlinear phenomena. These short pulses provide the means to open a new window to investigate ultrafast and nonlinear phenomena in condensed matter and energy research and fundamental aspects in nuclear and particle physics. The versatility in spectroscopy, microscopy and scattering experiments is obtained by generating photon beams in a wide range of wavelengths from the visible to the hard X-ray regime.

JuSPARC will be the first multi-purpose facility of its kind, accommodating local and regional research teams from a wide range of disciplines including condensed matter physics, materials science, structural biology, accelerator technology, plasma and nuclear physics. Among these are

The heart of JuSPARC will comprise a turn-key near-infrared femtosecond pulse laser system with three consecutive amplification stages reaching a final pulse power level in the PW range. The laser light from the different amplification stages is focused into highly specialized target areas, dedicated to short-pulse VUV, X-ray, electron, neutrons and proton beam applications, respectively.
