The present study reports the successful fabrication of CTO/Ag/CTO multilayer thin films with different sandwiched layer (Ag) thickness on a glass substrate by E-beam evaporation Method. influence and stacking layers electrical optical properties was investigated. Several analytical tools such as X-ray diffraction, Atomic Force microscopy, Hall Effect measurement, UV-visible spectroscopy were u...
Self-propagating exothermic formation reactions have been intensively studied in a variety of reactive multilayer foils, such as Ni/Al, Ni/Si, and Nb/Si foils. These foils contain numerous alternating nanoscale layers of elements with large negative heats of mixing. With a small thermal pulse, atoms diffuse normal to the layering and result in a rapid exothermic reaction. The heat produced is c...
A variety of microscopic techniques are employed to characterize fluence limiting defects in hafniakilica multilayer coatings manufactured for the National Ignition Facility. This work was performed under the auspices of the U.S. DOE by LLNL under contract No. W-7405-Eng-48. Characterization of fluence limiting defects in hafniakilica multilayer coatings manufactured for the National Ignition F...
For the European x-ray free electron laser (XFEL) a split-and-delay unit (SDU) based on geometrical wavefront beam splitting and multilayer mirrors is built which covers the range of photon energies from 5 keV up to 20 keV. Maximum delays between ∆τ ± 2.5 ps at hν=20 keV and up to ∆τ ± 23 ps at hν=5keV will be possible. Time-dependent wave-optics simulations have been performed by means of Sync...
Reflective optics is one of the most useful techniques for focusing a neutron beam with a wide wavelength range since there is no chromatic aberration. Neutrons can be focused within a small area of less than 1 mm 2 by high-performance aspherical supermirrors with high figure accuracy and a low smooth substrate surface and a multilayer interface. Increasing the mirror size is essential for incr...
