DOI: 10.1002/rcm.9436

Abstract: Rationale Chemical mass shifts in quadrupolar ion traps have been studied previously but only for a limited number of analytes and mass ranges. Here, mass shifts of cluster ions, commonly used as calibrants, and other… read more here.

DOI: 10.1016/j.ijms.2017.05.001

Abstract: Abstract Two theoretically equivalent methods of improving mass assignments in quadrupole ion traps operated using ac frequency scans are described side-by-side. Both use the inverse Mathieu q scan under constant rf conditions. In a first… read more here.

DOI: 10.1109/tasc.2024.3350588

Abstract: Trapped-ion qubits are one approach among many for achieving scalable quantum computers. An ion trap has to be operated with several dc and radio frequency (rf) signals to trap and control its qubits. Many ion… read more here.

DOI: 10.1109/tcpmt.2024.3418648

Abstract: Stringent physical requirements need to be met for the high-performing surface-electrode ion traps used in quantum computing and timekeeping. In particular, these traps must survive a high-temperature environment for vacuum chamber preparation and support high… read more here.

DOI: 10.1119/1.5034344

Abstract: We review the essential physics of microparticle electrodynamic ion traps (MEITs) and suggest several improvements in the design, construction, and application of MEITs in undergraduate physics teaching. Pulling together insights gleaned from a number of… read more here.
