Lasers & HI Accelerators

Advanced particle accelerators
(e.g. @ GSI and FAIR)
"... thus the technologies are complementary [intense light sources and ion beams] and both are likely to lead to new insights in high-intensity science."
National Research Council, USA, 2008
Novel lasers: Vulcan, POLARIS, DRACO,
PHELIX, ELI
Free electron lasers (e.g. LCLS @ SLAC)
