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: 10.1119/1.5034344
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.
