Abstract
A time-of-flight mass spectrometer includes a sample plate that supports a sample for analysis. A pulsed ion source generates a pulse of ions from the sample positioned on the sample plate. An ion accelerator receives the pulse of ions generated by the pulsed ion source and accelerates the ions. An ion detector includes an input in a flight path of the accelerated ions emerging from the field-free drift space and an output that is electrically connected to the sample plate. The ion detector converts the detected ions into a pulse of electrons.
