IDP Ion Desorption Probe.

The Hiden IDP is a quadrupole ion desorption probe for direct analysis of low-energy ions, neutrals and radicals generated in UHV surface science experiments. It supports electron-stimulated, photon-stimulated, and thermal desorption studies with positive- and negative-ion detection.

Direct low-energy ion analysis for stimulated desorption research

Four-lens ion optics with an integral electron ionizer collect externally generated species for mass and yield measurements. A pole bias mid-axis potential allows external ions to be measured, while pulse ion counting provides a continuous seven-decade display. Triple-filter quadrupole options and mass ranges to 5,000 amu extend sensitivity and high mass capability.

Signal gating to 100 ns supports mass distributions against time, including time-of-flight studies, and sample temperature can be displayed alongside thermal desorption data. This combination is designed for direct stimulated desorption measurements and low-energy ion analysis in UHV surface science experiments.
