Abstract
The production of negative H/D ions in cold plasmas is an important topics for fusion research. The Chapter deals with the mechanisms for the creation of negative ions including dissociative attachment from vibrationally excited H2/D2 molecules as well as from Rydberg states. Models based on the coupling of electron energy distribution function, vibrational kinetics and plasma chemistry in multipole magnetic plasmas are used and their results are validated against sophisticated experiments. Advanced particle models for the transport and extraction of negative ions from high power RF plasmas are then developed for fusion applications.
