20.500.12556/RUL-165204 Correlation between fluctuating electron temperature and fluctuating space-potential challenges the probe determination of turbulent electric field spectrum The measurement of plasma potential and electric field by the traditional Langmuir probe method can contain a significant qualitative error due to a spurious effect from temperature fluctuations that appear in the temperature-potential cross phase. This error is separate from any systematic error in the floating potential amplitude due to cross-correlated temperature and potential fluctuations not averaging out. Conditions under which electron temperature fluctuations significantly and insignificantly affect the measurement of electric field fluctuations in plasma are considered for both effects. Actual measurements illustrate the obtained conclusions are presented. Correct direct measurement of plasma’s space potential fluctuations requires that the amplitude of electron temperature fluctuations (in eV) be at least ten times smaller than the space potential fluctuation amplitude (in volts). electric probe electron temperature oscillations emissive probes magnetized plasma plasma potential oscillations električne sonde oscilacije elektronske temperature emisijske sonde magnetizirana plazma oscilacije plazemskega potenciala true false true Angleški jezik Slovenski jezik Članek v reviji 2024-11-27 07:23:25 2024-11-27 07:23:28 2026-05-16 04:59:39 0000-00-00 00:00:00 2024 0 0 Str. 1162-1167 no. 4 Vol. 52 Apr. 2024 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-12-04 2025-12-04 537.27 0093-3813 10.1109/TPS.2023.3337008 176472323 Yuan_..._Correlation_between_fluctuating_electron_temperature.pdf Yuan_..._Correlation_between_fluctuating_electron_temperature.pdf 1 320D16A00D692D84B344D4B45DADBBBF 3a1dd592579599b1d62d67ebc7a3a6a3ba5d5756d5a7c33e3c77542c38158636 9ab005c5-f9c5-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200359 https://ieeexplore.ieee.org/document/10339915 1 b560a4f7-ac87-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196234 Fakulteta za strojništvo Fakulteta za elektrotehniko 0 0 0
