I am interested in a wide range of problems involved in the preparation and execution of super resolution microscopy research. I support multiple project with design and instrumentation support. My interests include new technologic developments in fluidics, CFD, charged particle production/control, and vacuum system design.

The aerosol impact spectrometer: a versatile platform for studying the velocity dependence of nanoparticle-surface impact phenomena

Brian D. Adamson, Morgan E.C. Miller, Robert E. Continetti

EPJ Techniques and Instrumentation 4 2 (2017) | Journal

A new apparatus designed to accelerate/decelerate and study the surface impact phenomena of charged aerosols and nanoparticles over a wide range of mass-to-charge (m/z) ratios and final velocities is described. A nanoparticle ion source coupled with a linear electrostatic trap configured as an image charge detection (ICD) mass spectrometer allows determination of the mass-to-charge ratio and the absolute charge and mass of single nanoparticles. A nine-stage linear accelerator/decelerator is used to fix the final velocity of the nanoparticles, and in the results reported here the coefficient of restitution for polystyrene latex spheres (PSLs) impacting on silicon is measured using ICD techniques. To enable this apparatus to study a wide range of m/z, the data acquisition system uses a transient digitizer interfaced to a field-programmable gate array module that allows real time calculation of m/z and determination of the pulse sequence for the linear accelerator/decelerator. Electrospray ionization of a colloidal suspension of PSL spheres of 510 and 990 nm has been used to demonstrate acceleration and deceleration of charged nanoparticles and the resolution of the apparatus. Measurements of the coefficient of restitution for PSLs on silicon over the range 10-400 m/s are consistent with previous studies.

Miller, M.E.C., Characterizing the Impact Dynamics of Small Particles: The Aerosol Impact Spectrometer. Ph.D. Dissertation, University of California San Diego, La Jolla, CA

Morgan Miller studied Physics (B.S.) at the University of California, San Diego (UCSD) from 2010 to 2014. He received his Ph.D. in the Nanoengineering department at UCSD in 2020, working with Prof. Robert Continetti. His research topic was the development of novel laboratory instrumentation for studying the impact dynamics of sub-micron particles in collaboration with both ASML and the Jet Propulsion Laboratory. After graduating he joined the research groups of Dr. Stojan Madzunkov (Planetary Mass Spectrometry) and Dr. Morgan Cable (Exobiology Extant Life Surveyor) as a postdoctoral researcher. Morgan accepted a position in the Life Science Mass Spectrometry RnD group of Thermo Fisher Scientific in 2021 with the ion source development team. In 2024 he joined the group of Prof. Vahid Sandoghdar at the Max Plank Institute for the Science of Light to work on experimental development in iSCAT microscopy.
