被引用回数：27 パーセンタイル：55.97(Physics, Multidisciplinary)This paper reviews a series of studies that address the development and application of aperiodic multilayer structures (aperiodic multilayer mirrors) as soft X-ray (SXR) (
4-40 nm) optical elements. The paper discusses the potential of such structures for reflecting SXR radiation in a broad wavelength range, primarily at normal radiation incidence; and as polarization elements (broadband polarizer mirrors and phase shifters). Also, the capabilities of aperiodic structures as elements of attosecond SXR optics are discussed.

被引用回数：97 パーセンタイル：84.8(Physics, Multidisciplinary)The paper examines the prospects of using laser plasma as a source of high-energy ions for the purposes of hadron beam therapy - possibility which is expected not only on theoretical grounds but also on experimental grounds (ions are routinely observed to be accelerated in the interaction of high-power laser radiation with matter). Compared to therapy accelerators like cyclotrons, laser technology is advantageous in that it is more compact and is simpler in delivering ions from the accelerator to the treatment room. Special target designs allow the radiation therapy requirements on ion beam quality to be satisfied.

被引用回数：100 パーセンタイル：82(Physics, Multidisciplinary)Relativistic flying mirrors in plasmas are thin, dense electron or electron-ion layers accelerated by high-intensity electromagnetic waves to velocities close to the speed of light in the vacuum; in nonlinear media, refractive index modulations are induced by a strong electromagnetic wave. The reflection of the electromagnetic wave from the relativistic mirror results in its energy and frequency changing. In the counter-propagation configuration, the frequency of the reflected wave is multiplied by the factor proportional to the 
-factor squared. This scientific area promises the development of sources of ultrashort X-ray pulses in the attosecond range. The expected intensity will reach the level at which the effects predicted by nonlinear quantum electrodynamics start to play a key role. In the co-propagating configuration, the energy of the electromagnetic wave is transferred to the ion energy, providing a highly efficient acceleration mechanism.
