Abstract
We have tested at Super ACO (LURE) a new angular resolved photoemission device for the 12-30 eV energy range, using multidetection of photoelectrons: all all electrons emitted in a plane are collected and focused onto a fluorescent screen in a coordinate grid directly related to (E(i), k parallel-to). This multidetection provides a substantial diminution of the acquisition time. Ten seconds are needed to obtain a complete off-normal set of energy distribution curves (EDC). Real time visualization of the valence-band structure for one azimuthal plane is even possible. Digital image treatment is performed after the experiments, permitting an easier extraction of the characteristics of the bands and the emission structures.
