Characteristics of the pressure profile in the accelerator on the RF negative ion source at ASIPP
Nanotechnology and Precision Engineering, 2023 Neutral beam injection (NBI) systems based on negative hydrogen ion sources—rather than the positive ion sources that have typically been used to date—will be used in the future magnetically confined nuclear fusion experiments to heat the plasma.

Gravitational lens time delays and gravitational waves [PDF]
Physical Review D, 1994 Using Fermat's principle, we analyze the effects of very long wavelength gravitational waves upon the images of a gravitationally lensed quasar. We show that the lens equation in the presence of gravity waves is equivalent to that of a lens with different alignment between source, deflector, and observer in the absence of gravity waves.

Oscillations in the stochastic gravitational wave background from sharp features and particle production during inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We identify a characteristic pattern in the scalar-induced stochastic gravitational wave background from particle production during inflation. If particle production is sufficiently efficient, the scalar power spectrum exhibits 𝒪(1) oscillations periodic

On The Interaction of Gravitational Waves with Magnetic and Electric Fields
, 2010 The existence of large--scale magnetic fields in the universe has led to the observation that if gravitational waves propagating in a cosmological environment encounter even a small magnetic field then electromagnetic radiation is produced. To study this

Nonlinear Interactions Between Gravitational Radiation and Modified Alfven Modes in Astrophysical Dusty Plasmas [PDF]
, 2006 We present an investigation of nonlinear interactions between Gravitational Radiation and modified Alfv\'{e}n modes in astrophysical dusty plasmas. Assuming that stationary charged dust grains form neutralizing background in an electron-ion-dust plasma ...
