Abstract
Room-temperature, compact Penning traps have been shown recently to be useful for capture and storage of highly-charged ions extracted from an EBIT ion source at the National Institute of Standards and Technology (NIST). Highly-charged argon and neon ions extracted with energies of up to 4000 eV/Q are captured in such traps with well depths of 4 eV/Q – 12 eV/Q. Here we discuss in detail the technique of slowing, capture, and storage of energetic, highly-charged ions in a unitary Penning trap. Near optimal capture conditions, ions isolated in such rare-earth Penning traps can be characterized by an initial temperature that is lower by a factor of 60 than typically found in an EBIT, a step towards the low-energy regime of interest for some precision experiments.
