Coulomb crystallization of xenon highly charged ions in a laser-cooled Ca+ matrix
Leonid Prokhorov, Aaron A. Smith, Mingyao Xu +17
We report on the sympathetic cooling and Coulomb crystallization of xenon highly charged ions (HCIs) with laser-cooled Ca ions. The HCIs are produced in a compact electron beam…

Integration of high-performance compact interferometric sensors in a suspended interferometer
Alexandra Mitchell, Johannes Lehmann, Philip Koch +6
Homodyne Quadrature Interferometers (HoQIs) are compact, low noise and high dynamic range displacement sensors designed for use in gravitational wave observatories. Their lower noi…

Sensitivity and control of a 6-axis fused-silica seismometer
Jiri Smetana, Amit Singh Ubhi, Emilia Chick +12
We present a pair of seismometers capable of measurement in all six axes of rigid motion. The vacuum-compatible devices implement compact interferometric displacement sensors to su…
