We give direct experimental evidence for the observation of full transverse self-modulation a long, relativistic proton bunch propagating through dense plasma. The exits plasma with periodic density modulation resulting from radial wakefield effects. show that is seeded by ionization front created using an intense laser pulse copropagating bunch. extends over length following seed point. By varying one order magnitude, we frequency scales expected dependence on density, i.e., it equal to...
The seeded self-modulation of a relativistic, charged particle bunch in plasma is shown to grow both along the and plasma, resulting transverse wakefield amplitudes that far exceed initial seed values.
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here ready for systematic study of seeded self-modulation 400\,GeV proton bunch in 10\,m-long rubidium with density adjustable from 1 to 10$\times10^{14}$\,cm$^{-3}$. short laser pulse used ionization vapor propagates all way along column, suggesting full vapor. occurs bunch, at time and follows affects bunch.
The laser field dependence of the intersubband optical absorption in a graded quantum well (GQW), under an applied electric is calculated effective mass approximation. We have theoretically shown that, GQW structures, not only 'dressed' potential but also direction external plays very important role transitions.
Abstract The nonlinear optical rectification, the second harmonic generation coefficient, and third coefficient in parabolic-inverse parabolic-parabolic quantum wells (PIPPQWs) inverse parabolic-parabolic-inverse parabolic (IPPIPQWs) are calculated varying intense laser field (ILF) parameter ( <?CDATA ${\alpha _0}$?> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msub> <mml:mi>α</mml:mi> <mml:mn>0</mml:mn> </mml:msub> </mml:mrow> </mml:math> )....
The intersubband absorption in symmetric double quantum wells under the laser field is theoretically calculated within framework of effective mass approximation. Results obtained show that intersubbband optical transition and energy levels well can significantly be modified controlled by intense field. This statement gives a new degree freedom various device applications based on electrons.
