摘要: This paper presents a new design of ion sensitive probe (ISP) that enables collection pure current for accurate measurement the perpendicular temperature in magnetized plasmas. The type ISP resolves longstanding issue widely observed measurements, namely, current-voltage characteristic is smeared by an unexpected electron standard model. equipped with fine scale metal mesh on sensor entrance to prevent electrons from flowing sensor, phenomenon considered be caused space-charge effect. successfully measured cyclotron resonance
