The physics and technology of ion sources pdf
WebbIon sources are necessary to form ions for mass spectrometers and other types of instruments. In comparison to Penning ionization sources, the duoplasmatron features advantages such as less expenditure, easier handling, and a longer lifetime. However, the duoplasmatron does have lower beam intensity, which can be a large disadvantage. [4]

We find that….
WebbOne of the main parts is ion source to produce positive deuteron ions which will bombard the target to produce fast neutrons. There are some types of an ion source for a compact neutron generator, one of which is radio frequency (RF) ion source. The advantage of the RF ion source is that most of the produced ions (> 80%) are atomic ions. Webb3 apr. 2014 · The basic notions of vacuum technology for ion sources are presented, with emphasis on pressure profile calculation and choice of pumping technique. A Monte Carlo code (Molflow+) for the evaluation of conductances and the vacuum-electrical analogy for the calculation of time-dependent pressure variations are introduced.
