Alpha

Crossed-beam Imaging

The crossed-beam machine “Alpha” is optimized for DC slice imaging studies of reactive scattering with universal VUV probe. The machine has been used extensively for systematic investigation of the reaction dynamics of C3 and larger hydrocarbons with Cl, O and OH radicals. Current efforts focus on S(3P) reactions with these and other targets. This effort is supported by the US Department of Energy Office of Basic Energy Sciences.
