WebIn general, the cylindrical Langmuir probes proved to be a good tool in studying ionospheric ion mass spectra and temperature together with electron temperature since … WebThe probe consists of a collector, a guard, and a sleeve electrode. Besides being easier to construct, this modified probe geometry is more amenable to numerical verification of its operating properties. Such a verification is carried out by numerically following selected collisionless orbits of charged particles in the electric field of the probe.
