Crystals of 40Ca+ and 9Be+ in a Compact Penning Trap
Abstract
Penning ion traps are useful experimental platforms for quantum simulation, mass spectrometry, precision metrology, molecular spectroscopy, and measurements of fundamental constants. We recently developed a compact, permanent-magnet based Penning trap that is compatible with cold ion physics experiments at 0.6 T. We will describe the results of trap magnetic field characterization (both stability and uniformity) using confined, laser-cooled 40Ca+ and 9Be+ as probes. We have also demonstrated a laser cooling technique for 40Ca+ at high magnetic field that allows for spin state detection without the need for shelving to metastable D levels. This cooling and detection scheme reduces the laser requirements for Penning trap experiments with atomic ions possessing low-lying D states.
