Registration of a particle by a time-to-digital converter in secondary ion mass spectrometry.
Note: The arrival time for each ion providing a pulse at the detector is registered by the time-to-digital converter (TDC). This is a stop event. TDCs might only record a fixed number of stop events during the time following each primary-ion pulse, for example 512 or 1024, other events being lost.
