A. Lindell et al., PRODUCING AR-GUIDE EXPERIMENTS BY A CORONA DISCHARGE( IONS FOR ION), Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 378(1-2), 1996, pp. 258-261
A tiny corona discharge burning in the thermalization chamber of an io
n guide is used for producing Ar+ ions. Tested ion currents range from
50 nA to 0.01 pA. The beam does not contain electrons nor negative io
ns.
