Title: Development of Auger-Electron-Ion Coincidence Spectrometer to Study Decay Dynamics of Core Ionized Molecules

Abstract

A new electron-ion coincidence spectrometer for studies on decay dynamics of core excited/ionized molecules has been developed. The coincidence spectrometer consists of a double toroidal electron analyzer (DTA) and a three-dimensional ion momentum spectrometer, which are followed by time- and position-sensitive detectors (PSDs). The Auger electron is energy analyzed by the DTA, while the ions are extracted from the interaction region by a pulsed electric field triggered by the detection signal of the electron, and the time-of-flight of the ions and their position information on the ion PSD are obtained. The design and performance of the coincidence spectrometer are reported.
