E. Beebe et al., EXTERNAL ION INJECTION INTO AN EBIS SOURCE - EFFICIENCY MEASUREMENTS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 93(3), 1994, pp. 378-381
A concept for a charge state multiplier, to be used for the production
of energetic radioactive ion beams based on the ISOL+ post-accelerato
r system, is discussed. The charge state breeder implies external ion
injection into an electron beam ion source (EBIS). The total efficienc
y, measured by injecting a low-energy nitrogen (Q = 1+) beam, reached
14.5% and was essentially constant for confinement times up to 200 ms.
