Multiply-ionized atoms isolated at low energy in a unitary Penning trap
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 [1]. Measurements after 1 ms of ion storage indicate that the isolated ions are distributed with 5.5(5) eV of energy spread, which is roughly 2 orders of...

| description | 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 [1]. Measurements after 1 ms of ion storage indicate that the isolated ions are distributed with 5.5(5) eV of energy spread, which is roughly 2 orders of magnitude lower than expected in the ion source, without implementing any active cooling [2]. 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 quantum electrodynamics (QED) and determinations of fundamental constants [3]. |
