A multipurpose electron-ion spectrometer for measurements with synchrotron radiation

A multipurpose system has been constructed for ion and electron measurements. The system can be used as a time of flight ion mass spectrometer, conventional electron spectrometer or threshold electron spectrometer. In the future it is planned to use the system as a coincidence spectrometer between ions and electrons with selected kinetic energies. The construction of the system is described and some measured spectra are presented. (C) 2001 Elsevier Science B.V. All rights reserved.
