Abstract

A charge compensation system, based on a pulsed lowenergy electron flood source, designed for the 1X23S time‐of‐flight secondary ion mass spectrometry (TOFSIMS) instrument is described. Its performance in the non‐imaging mode is illustrated by spectra from polytetrafluoroethene (PTFE). High‐resolution (∼1 pm) imaging of challenging insulating samples under near‐static SIMS conditions is demonstrated for the first time.

This work presents a direct comparison of two pixel detectors: a charge-integrating flat panel imager coupled to a CsI:Tl scintillator and a hybrid silicon detector of Medipix2 type, working in a singlephoton counting mode. The comparison concerns image quality in terms of system-spatial resolution,
