H−ion formation from a surface conversion type ion source

New Dual-type Electron Cyclotron Resonance Ion Source for a Universal Source of Synthesized Ion Beams*

A new dual-type source has been constructing on the basis of electron cyclotron resonance (ECR) plasma for producing synthesized ion beams in Osaka Univ. Magnetic field in the 1st stage consists of all permanent magnets, i.e., cylindrically comb shaped one, and that of the 2nd stage consists of a pair of mirror coil, a supplemental coil and the octupole magnets. Both stage plasmas can be indivi...

Emission Performance of a Slit Type Caesium Field Ion Source

Results are reported of a study of the emission performance of a slit type liquid caesium field ion source which oriqinally was developed by the European Space Research and Technology Centre a s an ion thruster for electric space propulsion. The emission site distribution and the ion beam divergence are examined a s a function of the wetting properties at the emitter slit edge.

Experiments on neutralized beam extraction from a laser ion source

Particle loss due to space charge effects is a severe problem in the low energy section of accelerators. The extraction system and beam transport sections are the most sensitive parts. Especially for the case of a laser-ion source (LIS) the extraction of ions from very dense plasma can lead to a high current density in the extraction gap. To make use of this high current density (i.e. to maximi...
