 note = {A direct display plasma density and temperature meter based on Langmuir probe method has successfully be applied in the density and temperature measurement by a sounding rocket. An 1 kHz AC voltage is superposed on the DC sweep voltage of Langmuir probe and the DC voltage is automatically fixed at the inflection point of the Langmuir probe characteristics by detecting the 2nd harmonic component (2 kHz) of the AC current. The density and temperature are obtained from the DC and AC (1 kHz) currents at the inflection point using a newly developed digital calculator system., 資料番号: SA0124554000},
