Rocket Observations of Plasma Density Irregularities in the Polar E Region
Antarctic Record, 1975 On the records of electron densities obtained by the Langmuir probe, the superpositions of rapid fluctuations (10-100Hz) are often detectable in the auroral E region. These density irregularities have not been investigated in detail because the design of

Voltammetric determination of the critical micellar concentration of surfactants by using a boron doped diamond anode [PDF]
, 2010 The electrochemistry of three surfactants has been studied by voltammetry at boron doped diamond (BDD) electrode in sodium sulphate solutions. The electrochemical behaviour of these surfactants is characterized by an oxidation signal (peak or wave ...

Contamination effects on fixed-bias Langmuir probes
Review of Scientific Instruments, 2012 Langmuir probes are standard instruments for plasma density measurements on many sounding rockets. These probes can be operated in swept-bias as well as in fixed-bias modes. In swept-bias Langmuir probes, contamination effects are frequently visible as a hysteresis between consecutive up and down voltage ramps.

Evaluation of axial decay length of plasma pressure in detached plasma
Nuclear Materials and Energy, 2020 This study proposes a method for evaluating the axial decay length of the plasma pressure in detached helium plasmas with a fixed-point laser Thomson scattering and spectroscopic measurements in the linear divertor plasma simulator NAGDIS-II.
