Correlated Atomic Dynamics Half-cycle pulses: t ~ 5 fs … 1 as I = 1016 W/cm2 Collisions: vary the interaction strength vary (and access) ultra-short interaction times vary the charge sign Chance for rigorous theory Atom: t ≈ 150 as I = 1016 W/cm2

Correlated Atomic Dynamics Half-cycle pulses: t ~ 5 fs … 1 as I = 1016 W/cm2 Collisions: positive ion e- impact ionization threshold ion impact electron transfer / quasi-molecules Atom: t ≈ 150 as I = 1016 W/cm2 p impact a unique and the only tool!

A Reaction Microscope for ELENA ~ 500 mm CF200 chamber (NEG-coated) 300 mm e--Detector Turbo-Pump ~ 700 mm CF100 beam-tube gas-jet (from top) ELENA-beam free aperture (is flexible up to 100 mm if needed) CF100 valves Helmholtz-coils Turbo-Pump recoil-Detector

Space requirements: About 500 mm free space in the beam-line (minimum). Anticipated vacuum conditions: UHV or XHV in the main chamber (10-11 – 10-13 torr range). Supersonic gas-jet: Several differential stages (ideally 4 for the source, 3 for the dump). Desired ELENA beam parameters: Small beam diameter at interaction point (1 mm would be close to ideal). Low energies (50 keV or less). An option for bunched beams (with buckets of a few ns) would significantly extend the accessible physics program.
