The instability is due to the poloidal magnetic field and/or the rotation of the cylinder in combination with the densityprofile. Quite unexpectedly, the contributions of the two terms of the master equation to the densityprofile are of the same order of magnitude. The plasma densityprofile is defined by (4.4). In an underdense plasma layer with linearly descending densityprofile, the accelerated electrons move together with the laser pulse which propagates with increasing group velocity. Characterization of neutral densityprofile in a wide range of pressure of cylindrical pulsed gas jets. As one can see, the profiles are converging to a well-defined, stationary, densityprofile. The resulting equation of evolution of the densityprofile involves a convolution in time. The transverse intensity gradient generates a ponderomotive force, which modifies the plasma densityprofile in the transverse direction. The calculation can be modified without difficulty to a different ion correlation function and corresponding radial electron densityprofile. An algorithm for reconstructing the densityprofile from a measured wake-field spectrum is given and illustrated with a numerical example. It should be noted that the axial gradient in the initial densityprofile due to the expansion fan is enough to initiate the instability. The neighbouring stable state is associated with a less concave or more convex current densityprofile. So, the effect of increasing group velocity can be extruded in such an imaginary densityprofile. However, the actual radial plasma densityprofile is known to be far from uniform. In reality such a piston has to move through an inhomogeneous densityprofile. The densityprofile at this time is superimposed. We then assume a plasma and neutral gas densityprofile (2.12b). Continuing in this manner, one finds that the procedure does converge to a stationary densityprofile. To obtain the simple-wave solution, one specifies the initial densityprofile at time t l 0 : (5.17) (x, 0) l i(x). The densityprofile has a minimum on the axis. The results of the simulation show that the required plasma densityprofile can be obtained in this way. We gradually increase the number of electrons per mesh to track the obtained densityprofile up to 200 electrons per mesh at twice critical density. The densityprofile of photoreceptors in wholemounts varied from the dorsal to the ventral retina. The implied steepening of the densityprofile indicates that the reduction of neutral pressure is accompanied by a change in the source profile. The initial densityprofile shows a spectrum with larger amplitudes at longer wavelengths. The spreading of the densityprofile results in a larger flux of ions accelerating through the sheath and impacting on the wall. The overlapping of the electron densityprofile with that of the ions is expected to maximize the two-stream interaction and therefore the growth rate. The density is calculated relative to the background densityprofile for a given value of the x coordinate. These examples are from corpora and from sources on the web.
