HZDR – Facts and Figures
Research Questions and Large-Scale Facilities
How can cancerous tumors be identified in the early stages and treated effectively?
Radiation Source ELBE Free-Electron-Lasers High-Intensity Laser
High Magnetic Field Laboratory Dresden
Advanced Materials Research
How does matter behave in strong fields and at small dimensions?
Ion Beam Center
Rossendorf Beamline ROBL at the ESRF
Nuclear Safety Research
How can the public and the environment be protected from technical risks?
Unique combination of:
high-power high-brilliance CW electron beams, synchronized with
high rep-rate, ultra-high intensity lasers.
new radiation sources, in unique combinations, enablingstudy of matter under extreme conditions & in new regimes.
Will constitute a prototype for future facilities:
National Center for Radiation Research in Oncology-Dresden,
and Helmholtz beamline at XFEL, or FAIR.

Petawatt, Energy-Efficient Laser for Optical Plasma Experiments
Development of a 2nd generation directly diode laser pumped short pulse PW laser
(design: 150J in 150fs, >1Hz rep. Rate, active medium Yb:CaF2 discs )
based on the 1st generation project POLARIS at IOQ Jena
Complemented by running 150TW Ti:Sapphire
laser Draco (upgrade to PW level in progress)
From POLARIS (IOQ Jena) to PEnELOPE (HZDR)
