Plasma Channel Formation Through Laser Resonance Saturation
Mark A. Cappelli, S. K. Wong, R. S. Kissack +1
We have developed a computer code that models the three dimensional nature of a sodium plasma created by laser resonance saturation. This was accomplished by taking account of the…
Electron Density Measurements from Stark Broadened Emission in a Sodium Plasma Produced by Laser Resonance Saturation
Mark A. Cappelli
Electron Stark broadening of the -- multiplet transition in a sodium plasma produced by laser resonance saturation has provided a means of undertaking the first spatial…
Time Evolution of the Pinch Region of a Deflagration Plasma Accelerator
A. A. T. Jibodu, J. D. Strickland, M. A. Cappelli
A spectroscopic study of a plasma deflagration accelerator was carried out to investigate the temporal evolution of plasma density within the pinch region. A half-meter imaging mon…
Low-energy spectrum of the BULLKID detector array operated on surface
D. Delicato, A. Ahmad, L. Bandiera +14
We present the first continuous operation in a surface lab of BULLKID, a detector for searches of light Dark Matter and precision measurements of the coherent and elastic neutrino-…
Inverse design and experimental realization of plasma metamaterials
Jesse A. Rodriguez, Mark A. Cappelli
We apply inverse design methods to produce two-dimensional triangular-lattice plasma metamaterial (PMM) devices which are then constructed and demonstrated experimentally. Finite d…
High-Pressure CO Dissociation with Nanosecond Pulsed Discharges
Erwan pannier, Taemin Yong, Christophe Laux +1
The efficiency of the conversion of CO into CO with nanosecond repetitively pulsed discharges (NRP) is investigated in a high pressure batch reactor. Stable discharges are obta…
Inverse design of plasma metamaterial devices with realistic elements
Jesse A Rodriguez, Mark A. Cappelli
In an expansion of a previous study [1], we apply inverse design methods to produce two-dimensional plasma metamaterial devices with realistic plasma elements which incorporate qua…
Plasma-fixated nitrogen as fertilizer for turf grass
Christina Sze, Benjamin Wang, Jiale Xu +2
We investigated the use of plasma-fixated nitrogen, which produces nitrates (NO3-) in water, as a possible nitrogen fertilizer for recreational turf such as ryegrass and bentgrass.…
Dual Mode Operation of a Hydromagnetic Plasma Thruster to Achieve Tunable Thrust and Specific Impulse
T. C. Underwood, W. Riedel, M. A. Cappelli
We report here on initial studies of a pulsed hydromagnetic plasma gun that can operate in either a pre-filled or a gas-puff mode on demand. These modes enable agile and responsive…
Laser Absorption Measurements of Electron Density in Nanosecond-ScaleAtmospheric Pressure Pulsed Plasmas
T. Yong, A. I. Abdalla, M. A. Cappelli
We report on time-resolved measurements of electron number density by continuous-wave laser absorption in a low-energy nanosecond-scale laser-produced spark in atmospheric pressure…
Inverse design of plasma metamaterial devices for optical computing
Jesse A. Rodriguez, Ahmed I. Abdalla, Benjamin Wang +3
We apply inverse design methods to produce two-dimensional plasma metamaterial (PMM) devices. Backpropagated finite difference frequency domain (FDFD) simulations are used to desig…
Perspectives on Physics of ExB Discharges Relevant to Plasma Propulsion and Similar Technologies
Igor D. Kaganovich, Andrei Smolyakov, Yevgeny Raitses +22
This paper provides perspectives on recent progress in the understanding of the physics of devices where the external magnetic field is applied perpendicularly to the discharge cur…
Effects of Flow Collisionality on ELM Replication in Plasma Guns
Thomas C. Underwood, Vivek Subramaniam, William M. Riedel +2
Degradation of first wall materials due to plasma disturbances severely limit both the lifetime and longevity of fusion reactors. Among the various kinds of disturbances, type I ed…

Benjamin Wang, Jesse Rodriguez, Mark A. Cappelli
A 3D woodpile structure tunable plasma photonic crystal is designed, simulated, and experimentally characterized over the S - X band of the electromagnetic spectrum. The measuremen…

Gaseous Plasmonic Resonators for Metamaterial Applications
Roberto A. Colón Quiñones, Thomas C. Underwood, Mark A. Cappelli
We examine the properties of a gaseous plasma resonator generated by focusing a high-energy laser pulse through a lens and into a gas. An analytical model is presented describing t…
