Design and implementation of a custom imaging mass spectrometer.
… chemical analysis. As such, MS has found application across practically every field of science today. One notable area where MS is used today is in the analysis of biological samples, such as tissues, where MS has been utilized for lipidomic, proteomic, metabolomic, etc. The work contained in this …

Modeling of complex surface interactions in low and high pressure plasmas
… (or dry etching) is widely used in the fabrication of integrated cir-cuits (IC). Anisotropic features are easily obtained by controlling reactive ion trajectories in plasma. Twisting and bowing are two main issues during high aspect ratio (HAR) fea-ture etching. Twisting is, instead of a feature …

Development of Ion Mobility Mass Spectrometry Instrumentation to Investigate the Gas-Phase Structures of Protein and Protein Complex Ions
This dissertation reports the development of new ion mobility mass spectrometry (IM-MS) instrumentation to analyze protein and protein complex ions. IM-MS is a gas-phase analytical technique that separate ions based on their collision cross section (a description of ion shape) and mass-to-charge …

Surface damage through grazing incidence ions investigated by scanning tunneling microscopy
Surface damage, caused by grazing incidence ions, is investigated with variable temperature scanning tunneling microscopy. The experiments are carried out on a Pt(111) crystal. The kinetic energy of noble gas ions is varied between 1-15 keV and the angle of incidence can be adjusted between 78.5° …

Study of Coulomb collisions and magneto-ionic propagation effects on incoherent scatter radar measurements at Jicamarca
In this dissertation, Coulomb collisions and magneto-ionic propagation effects on the incoherent scatter radar measurements have been studied and analyzed in detail. The present study aims at modeling radar observations of the equatorial ionosphere carried out at the Jicamarca Radio Observatory …
