Variable gain detection strategy for time-of-flight multiphoton ionization spectroscopy experiments

This note presents a new, simple approach to measure time-of-flight mass spectra containing ions in a wide concentration range as generated by laser photoionization studies of van der Waals complexes.

Zusammenfassung:This note presents a new, simple approach to measure time-of-flight mass spectra containing ions in a wide concentration range as generated by laser photoionization studies of van der Waals complexes. Real-time control of the gain of the microchannel plate detector, applying to it fast-rising high-voltage pulses like in slice imaging experiments, is suggested. Results are presented for a model system study.
