Microscope mode secondary ion mass spectrometry imaging with a Timepix detector. [PDF]

open access: yes, 2013
In-vacuum active pixel detectors enable high sensitivity, highly parallel time- and space-resolved detection of ions from complex surfaces. For the first time, a Timepix detector assembly was combined with a secondary ion mass spectrometer for microscope
