EXPERIENCE

2009-2017 Beamwave Research, Inc. Naval Research Lab, D.C. Research Scientist, Electromagnetics Technology Branch, Code 6850

Analyzed thermal and mechanical stresses due to current loads on collectors within advanced vacuum electron devices using Ansys simulation software.

Planned and executed series of experiments to study distortion effects on TEW radar waveforms due to saturation of TWT amplifiers. Collaborated with theorists and TWT design team to improve modeling of TWTs to overcome distortion effects.

Designed and implemented adaptive system for testing pulsed r.f. amplifiers of varying power and frequency bands in order to establish drive curves and gain values over the full bandwidth of the amplifier.

Collaborated on designing a system to measure the drive curve and bandwidth of a 200 GHz, 5 W amplifier, and made the measurements on the new amplifier.

Designed and built experiment to test laser emission from a novel LED when driven with an electron beam. Used an electron gun designed by Beamwave Research to drive the LED at varying currents in a vacuum vessel and monitor ultraviolet emissions from the LED.

Participated in series of experiments on using thin-film diamond as an electron beam amplifier. Successfully created a technique to cleanly bond 4-10 μm thick flakes to a thicker diamond substrate. Also performed experiments establishing low temperature hydrogenation of the diamond emission surface.

Executed series of experiments to bond ferroelectric transducers to silicon wafers at low temperature using compression bonding of an In-Pt-Ti coating.

Refurbished and wrote LabVIEW controls for photoemission electron microscope, photoemission energy analyzer, and in situ scanning electron microscope.

Participated in experiments to investigate mobility of cesium on tungsten for use in cesium-tungsten cold cathodes.

2004-2008 University of California, San Diego La Jolla, CA 2007-2008 Assistant Project Scientist, Center for Energy Research

Led experiments on high-temperature transients on carbon-beryllium mixed materials for ITER relevant plasma facing components, establishing the detrimental effects of materials mixing in an ITER-like device.

Planned and executed experiment to study angular sputtering rate of tungsten nano-structured surfaces due to argon plasma exposure at varying impact energies.

Designed and built control system for new high-temperature thermal desorption spectrometer, and began series of experiments on the gas retention of tungsten nano-structured surfaces exposed to hydrogen, helium, and mixed-gas plasmas.

2004-2006 Postdoctoral Researcher, Center for Energy Research

Planned and executed experiments to study carbon film formation in carbon-grid ion thrusters.

Participated in experiment to measure angular sputtering of molybdenum and carbon clusters using QMS. J E R EMY H A N N A E - M A I L : D R . J E R EMY.H A N N A @GMAIL.C OM 3 of 3

Designed and built fast-sampling 2-color IR optical thermometer and spectral pyrometer for surface temperature measurements in pulsing experiments on PISCES.

Contributed to the design and implementation of a transient high-power system on PISCES.

Headed series of experiments on carbon and beryllium using pulsed power system to investigate high- temperature transients on ITER relevant PFCs.
