Measurements of electromagnetic waves in Phaedrus-B: Bench-mark test of ANTENA wave field calculations

It is shown that the predictions of a numerical code (ANTENA) and the data of wave field measurements in the Phaedrus-B tandem mirror are consistent (±25%) for right-handed (−) wave fields and less so (±40%) for left-handed (+) wave fields in the plasma core, and that they disagree for + fields near the column edge. Shorting out or reduction of the wave azimuthal electric fields by limiters is the probable cause of this discrepancy. The ICRF fluctuating wave fields are shown as || contour maps in the r-z plane, where the + data peak at a smaller radius than predicted. The waves are characterized by different dominant axial wave numbers for the left- and right-handed circularly polarized fields.

Phaedrus-Bタンデムミラーにおける数値コード(ANTENA)の予測と波動場測定データが、プラズマコア内の右回り(−)波動場については±25%の範囲で一致し、左回り(+)波動場については±40%の範囲で一致することが示される。また、プラズマ端付近では+波動場について一致しない。この不一致の原因は、リミッターによる波動の方位角方向電場の短絡または低減である可能性が高い。ICRF波動の変動場は、r-z平面における等高線図として示され、+データは予測よりも小さい半径でピークを示す。波動は、左回りおよび右回りの円偏波場において異なる支配的な軸方向波数によって特徴づけられる。
