Studies of Detector Surfaces


EMSL Project ID
6905

Abstract

We plan to study new designs and materials for mass spectrometer detector parts using surface analysis methods. One goal is to understand the relationship between detector anode design, materials and methods of construction, and detector properties including (but not limited to) such as primary ion recoil, secondary ion emission (both positive and negative) and electron emission. Surface composition and other information may be obtained to help understand the results of ion reflection and emission and electron emission measurements. We will use secondary ion mass spectrometry as one method of characterizing the detector parts. Ultimately, we are trying to design next generation anodes for mass spectrometers using novel designs and materials, and the measurements to be made in EMSL will help benchmark current technology and inform future design and materials choices.
