SPARC EBIT — a charge breeder for the HITRAP project

Charge breeding of externally injected, singly-charged ions in an electron beam ion source/trap (EBIS/T) extends the range of elements from which highly-charged ions can be produced with these machines, which is important for numerous atomic and nuclear physics experiments. Existing EBIS/T charge breeders feature electron guns producing intense beams and superconducting magnets generating strong fields to achieve high efficiencies and high ion charge states. We show an alternative possibility to inject, capture, charge-breed and extract ions using a compact room-temperature EBIT based on permanent magnet technology. Singly-charged potassium and rubidium ions injected over the barrier were charge bred and extracted as bare and neon-like ions, respectively. Simulations of injection and capture of singly-charged ions in this EBIT show the challenges and help understanding the results.
