Morgan}, title = {Application of Ion Sensitive Probe to High Density Plasmas in Magnum-PSI}, abstract = {Feasibility of an ion sensitive probe was evaluated in high electron density (> 5 × 1019 m−3) helium plasmas produced in the Magnum-PSI device. The ion sensitive probe showed that the ion temperature was ∼ 1 eV and almost equal to the electron temperature. Increasing the neutral pressure to efficiently lead to the electron-ion recombination processes, the electron currents were collected at the ion collector. A secondary electron emission in the guard electrode might have an effect on the ion current}, year = {2019}, journal = {Plasma and Fusion Research}, volume = {14}, pages = {1202135}, month = {06/2019}, doi = {10.1585/pfr.14.1202135}, language = {eng}, }
