Electric Field Optimization of High-Voltage Vacuum Feedthroughs
Lin Si, Evan Angelico, Giorgio Gratta
We report on the optimization of high voltage vacuum feedthroughs meant to minimize the electric field on the vacuum side of the device. We find that commercial feedthroughs genera…
Optomechanical vector sensing of new forces at 6 micron separation
Gautam Venugopalan, Clarke A. Hardy, Kenneth Kohn +10
The search for new gravity-like interactions at the sub-millimeter scale is a compelling area of research, with important implications for the understanding of classical gravity an…
Coupling of a Nuclear Transition to a Surface Acoustic Wave
Albert Nazeeri, Chiara Brandenstein, Chengjie Jia +2
Mechanical modulation of recoilless nuclear transitions allows the dynamic control of -ray emission and absorption. Accessing modulation frequencies well above the nuclear line…
Large field-of-view, distortion-corrected off-axis parabolic mirror relay microscope
Meimei Liu, Yuqi Zhu, Giorgio Gratta
Off-axis parabolic mirrors (OAPs) are occasionally desirable for specialized applications, but are known to introduce field-dependent astigmatic aberrations. In an experiment where…
A flexible test facility for liquid xenon detector development
Evan Angelico, Jacopo Dalmasson, Ralph DeVoe +6
As liquid xenon time projection chambers scale to ever-larger sizes, so too do the engineering challenges they pose. We describe a large, flexible, multipurpose test facility capab…
Platinum Black for stray-light mitigation on high-aspect-ratio micromechanical cantilever
Gautam Venugopalan, Giorgio Gratta
Microscopic devices are widely used in optomechanical experiments at the cutting-edge of precision experimental physics. Such devices often need to have high electrical conductivit…
