Multiply-ionized Atoms Isolated at low energy in a Unitary Penning Trap



Joseph N. Tan, Shannon Hoogerheide, Samuel M. Brewer, Nicholas D. Guise


Ions extracted from the EBIT at NIST are slowed and captured in a Penning trap that is made very compact (< 150 cm3) by a unitary architecture. Measurements after 1 ms of ion storage indicate that the captured ions are distributed with 5(1) eV of energy spread, which is roughly 2 orders of magnitude lower than expected in the ion source, without implementing any cooling. Some experiments are discussed. One goal is to produce one-electron ions in high angular momentum states for studying optical transitions between Rydberg states that could potentially enable new tests of QED and determination of fundamental constants.
