A helicon and a multicusp version of a radio-frequency ion source with compact permanent magnet systems for accelerator applications have been developed and tested to show the following performance data: plasma density of 10¹¹ - 9 x 10¹² cm^-3, pressure of 2 - 10 mTorr, beam current densities of 10 - 130 mA/cm², brightness ˜100 A/(m²rad² eV), energy spread 8 - 30 eV, and an rf power input into the plasma of 40 - 400 W. The design of a gas field ion source (GFIS) of the needle-in-capillary type operating at room temperature is proposed. A field ion emitter made on the nanostructured carbon basis is planned to be used in the source.
