Conceptual study of a toroidal electrostatic analyzer suitable for time-resolved XPS experiments with high flux synchrotron radiation sources
The use of new-generation synchrotron radiation sources for core-level photoemission will allow time-resolved experiments. On the other hand, the high flux will give rise to detector saturation problems. We present an electron analyzer which, because of its unique focusing properties, completely solves the difficulty. Moreover, because of its rotational symmetry, it will allow a simpler and more efficient design of the input lens system.
