My research group focuses on investigating the fundamental interactions between charged particles, electromagnetic radiation and materials. We are particularly interested in systems involving electrons, ions, with applications ranging from ionospheric physics  to materials processing.

General interests: Electromagnetics, fusion concepts, future enabling materials, traveling wave circuits, microwave vacuum electronics, plasma physics, circular and linear particle accelerators, electron and ion sources, pulsed power and radio frequency electronics.

 


Centrifugal Mirror Fusion Experiment (CMFX) – A simple, axisymmetric geometry and provides a potential low-cost pathway to a breakeven fusion experiment.

High Power Microwave (HPM) Group – Dedicated to designing, constructing and testing novel microwave structures including traveling wave tubes, gyrotrons, pasotrons and other high gradient accelerating microwave structures.

The Bright Beams Collective Research Group (BBC) is a world-class research facility in beam and accelerator physics at the Institute for Research in Electronics and Applied Physics on the University of Maryland, College Park campus. Using a scaled low-energy electron beam, BBC cleverly accesses the intense, high-brightness, regime of beam operation in accelerators at a much lower cost than larger and more energetic machines. BBC, therefore, makes an ideal testbed for experimenting in pushing up the brightness of existing and future accelerators.

Radiation Facilities – The University of Maryland Radiation Facilities includes a 250 kW reactor, 100 kCi Co60 source and two 10 MeV electron accelerators, supporting a broad range of Maryland research and the education of graduate and undergraduate students in nuclear science.

TEACHING AND MENTORING in ECE and the Keystone ProgramElectrical and Computer EngineeringAJamesClark

As an  Associate Research Professor, I created a new capstone course in 2023 called ENEE408J, "Audio Electronics Engineering." This course teaches 4th-year undergraduates the theory and experimental implementation of audio electronics that covers various implementations of filters/effects with multi-channel audio amplifiers, digital signal processing, electromagnetics, and physics of the various transducers, room acoustics, etc. The course has been taught in the spring of 2023, 2024 and will be offered in 2025.

I'm also teaching ENES100, "Introduction to Engineering Design" this fall 2024. This course provides new engineering students with a roadmap to becoming a professional engineer. This is achieved through the planning, investigation, design, manufacturing, assembly, and evalulation of a product, conducted within the context of a team.

I have also co-created a capstone course and offered it every spring semester (from 2016-2022), ENEE408T, "Building the 5 MeV Cyclotron." This course educates 4th-year undergraduates in the theory and operation of a particle accelerator known as the cyclotron. The students learn the fundamentals of the machine, and how to simulate various aspects of the machine: from the magnetic and RF fields to the particle dynamics. The course was taught in the spring semesters from 2016-2022.

I also continue to volunteer as an instructor for the United States Particle Accelerator School (USPAS). This 1-2 week school ventures around the country educating anyone interested in particle accelerators as well as the various subsystems. I have co-taught "Fundamentals of Accelerator Physics and Technology with Simulations and Measurements Lab", "Cyclotrons", "The effect of radiation on electronics and materials".

GEMSTONE HONORS PROGRAM-TEAM CHARGEX-MENTOR

I also mentor a small, selected group of students enrolled into the University of Maryland College Park program, known as the Gemstone Honors Program. The group I mentor is called "ChargeX" and they are interested in developing novel devices that could be used to charge electric vehicles and electric boats. I mentor them weekly to ensure their project stays on track with Gemstone deadlines. This mentoring occurs over a period of three years where I start working with the students in their 2nd year and by the time they graduate in their 4th year, they present an undergraduate thesis and a full report that includes all the work they have done. I assist the students with this report, both in editing and guiding them with the content.
