Constructing an Ultra-High Vacuum Chamber and a Radio Frequency Helical Resonator for Trapping Ions

We describe the construction of an ultra-high vacuum (UHV) chamber and a radio frequency helical resonator for use in co-trapping atomic and molecular ions. Cleaning procedures for the in-vacuum components are provided. These procedures give positive results in cleaning copper electrodes. The thesis also provides general UHV construction techniques and design choices for our UHV chamber. For th...

Note: Ultra-low birefringence dodecagonal vacuum glass cell.

We report on an ultra-low birefringence dodecagonal glass cell for ultra-high vacuum applications. The epoxy-bonded trapezoidal windows of the cell are made of SF57 glass, which exhibits a very low stress-induced birefringence. We characterize the birefringence Δn of each window with the cell under vacuum conditions, obtaining values around 10(-8). After baking the cell at 150 °C, we reach a pr...

A diamond-based scanning probe spin sensor operating at low temperature in ultra-high vacuum.

We present the design and performance of an ultra-high vacuum (UHV) low temperature scanning probe microscope employing the nitrogen-vacancy color center in diamond as an ultrasensitive magnetic field sensor. Using this center as an atomic-size scanning probe has enabled imaging of nanoscale magnetic fields and single spins under ambient conditions. In this article we describe an experimental s...

Design and initial characterization of a compact, ultra high vacuum compatible, low frequency, tilt accelerometer.

A compact tilt accelerometer with high sensitivity at low frequency was designed to provide low frequency corrections for the feedback signal of the Advanced Laser Interferometer Gravitational Wave Observatory active seismic attenuation system. It has been developed using a Tungsten Carbide ceramic knife-edge hinge designed to avoid the mechanical 1/f noise believed to be intrinsic in polycryst...
