Transport between the conference venue and HZDR will be organized.

During the DPG spring meeting, we would like to offer visits to our laboratories at HZDR to interested participants of the conference. Please register via e-mail to: .

 

Laser-driven plasmas – generated in the interaction of a focused high power laser pulse with a gas or solid surface – can sustain electrical field strength of 100 GV/m and above. This allows for compact  and efficient particle acceleration, generating electron pulses with hundreds of MeV and ion pulses with up to 100 MeV kinetic energies on mm and µm spatial scales, respectively. The particle pulses are ultra-short with femto- to picosecond pulse duration and feature extremely high pulse currents and dose.

The infrastructure for this exciting research field of plasma-based particle acceleration is available at the Helmholtz-Zentrum Dresden—Rossendorf (HZDR) with the DRACO titanium:sapphire high power laser system. Two independent beams from the DRACO laser allow for experiments with 150 TW and up to a Petawatt pulse power at three different experimental sites, optimized for electron and ion acceleration. In parallel, we are developing the fully diode-pumped PENELOPE laser system, its unique laser architecture (gain medium) in future providing 150 J pule energy in 150 fs with a repetition rate of 1 Hz.

Furthermore, HZDR hosts an electron-beam accelerator (ELBE) that produces various types of secondary radiation. One type is infrared and THz radiation in form of µJ pulses generated by the free-electron laser FELBE. At this laser we and external user groups perform various time-resolved experiments, in particular on semiconductors and novel 2D materials. The experiments shed light into the ultrafast dynamics on energy scales that match the low-energy excitations in these materials such as phonons, magnons or quantized electronic energies.
