1次元イオン流速ベクトル計測のための4視線ドップラー分光プローブアレイの開発

抄録

We developed a new Doppler probe array with two pairs of view-lines to measure 1D ion flow vector. Using this array, just two glass tube insertion enables us to measure 1D ion flow and temperature profile. By use of four mirrors for one measurement point, the system receives the emission of ion in four different directions and that enables us to measure local ion flow vector. It is useful for ion outflow measurement caused by magnetic reconnection.
