larmor radius造句

• The finite Larmor radius allows some ions to reach the electrode that would have otherwise gone past it.
• Since shadowing effects depend on the ion Larmor radius, the results can be interpreted in terms of ion temperature.
• At these parameters, the ion Larmor radius is a few millimeters, and the Debye length is tens of micrometres.
• In a magnetized plasma, the electrode is sometimes assumed to be increased in a similar way by the ion Larmor radius.
• When \ mathit l = 1 we recover the classical situation in which the electron orbits the magnetic field at the Larmor radius.
• In a magnetized plasma, it appears to be best to choose a probe size a few times larger than the ion Larmor radius.
• There are, however, cyclotron harmonics that can cause resonance diffusion in the velocity space leading to an unbounded Larmor radius enlargement and particle diffusion.
• Its scale is the ion Larmor radius at the sound speed, which is normally between the scales of the Debye sheath and the pre-sheath.
• If the field has a parallel gradient, a particle with a finite Larmor radius will also experience a force in the direction away from the larger magnetic field.
• As mentioned before, it might be necessary to increase the radius by about the thermal ion Larmor radius, but not above the effective area for the unmagnetized case.
• The probe consists of a conically shaped collector ( non-magnetic stainless steel, tungsten, copper, molybdenum ), which is shielded by an insulating tube ( boron nitride, Larmor radius.
• These drifts, in contrast to the mirror effect and the non-uniform " B " drifts, do not depend on finite Larmor radius, but are also present in cold plasmas.
• It is only physical reasoning, not mathematical necessity, that concludes that the ratio of the torus radius to the Larmor radius is important, and not, for example, the ratio to the Debye length.
• Here, r _ { 12 } is the distance between the centers of two current loops, e is the magnitude of the electron charge, r _ { B } = \ sqrt { 2 } \ mathit l _ B is the quantum version of the Larmor radius, and L _ B is the thickness of the electron gas in the direction of the magnetic field.
