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)

To “compete” with spontaneous decay channels one needs to

induce a two-photon PNC transition by polarised light with

intensity 1020 W/cm2

Relativistic HI EM Fields


The electric field produced by a moving charge (>>1) is nearly transverse (linearly polarised) and is accompanied by a transverse magnetic field of almost equal strength.

Back-scattered laser radiation from a compact electron ring (e.g. semi-commercial „Lyncean Compact Light Source“ would reach well above 100 keV.
