The dependence of Sn on electron density showed that Sn increased with an electron density of power of 3.1. To understand Sn, characteristics in the electron cyclotron heated plasma, a numerical simulation considering thermal deuterium-deuterium fusion reactions was performed. Although the numerical simulation overestimated Sn in a relatively low Sn region, calculated Sn matched the experimental result for a relatively high Sn region. A possible reason for the disagreement in the low Sn region is that effective charge due to the impurities such as carbon is changed because of the low density.}, title = {Neutron Emission Rate Characteristics of an Electron Cyclotron Heated Large Helical Device Deuterium Plasma}, volume = {16}, year = {2021} }
