Results of basic investigations on the influence of the magnetic fields and the meniscus shape on the extraction of negative ions, co-extraction of electrons and the beamlet quality are presented. 展开 关键词: low temperature plasmas particle in cell code negative ions plasma sheath ITER NBI ...
It is verified that the Gaussian components are caused by the negative ions extracted from the different plasma meniscus region, that is, the central region or the region near the edges of the meniscus.Journal of Physics: Conference Series
quantitatively from the viewpoints of the heat loads due to the beam halo in the accelerator and the emittance of the negative ion beam by using the 3D3V PIC model combined with a Monte Carlo calculation, in which negative ion beam from plasma meniscus formation to the beam acceleration is ...
A method and arrangement for preparation of mini-, semi-micro-and microsensors (26) in the form of liquid drop, gas bubble and liquid/liquid or gas/liquid meniscus is described. As a result, simply renewed sensors of volumes between 0.0007 and 1 mm can be obtained with very high ...
