摘要: A fast-sweep Langmuir probe (FSLP) diagnostic system was designed and applied to obtain the electron temperature fluctuations of a transient plasma. The consists single driven by high frequency sinusoidal voltage. current-voltage I-V characteristics can be recorded sweeping voltage measuring current with an appropriate circuit. This new instrument is based on dual channel circuit that compensates for stray capacitance. spectra were acquired from synchronously digital oscilloscope. aim this work apply FSLP time-dependent plasma generated hypervelocity impact between LY12 Aluminum projectile target.
