Present work continues research into the viability of commercially available small dimension carbonaceous media for ionizing radiation dosimetry and radiation damage studies, in part examining the relationship between structural alterations, surface-area-to-volume ratio and carbon content. Dose dependency characterizations have been undertaken for rods and sheets for a range of sources,...

There are two principal ways to achieve ultra-high spectral resolution and maximal diffraction efficiency by blazed (with triangular groove profiles) gratings in the short-wave range (from hard X-rays to vacuum UV): (1) using high-orders diffraction with low and medium groove densities; (2) using first-orders diffraction with high and ultra-high groove densities. Due to the hard-to-solve...

The relaxation of the polarization of the medium as a result of interaction with charged particles leads to the formation of various types of radiation processes. Examples that have been studied in detail in the literature include Cherenkov radiation (CR), transition radiation, and diffraction radiation. The radiation processes mentioned above are also sources of electromagnetic radiation...

When the Chirped Pulse Amplification allowed to amplify ultrashort laser pulses, generated in mode-locking mode, it became possible to use the intense electric fields of the plasma electron waves to accelerate electrons up to a few GeV on centimeter scale. The physical mechanisms on which is based this innovative acceleration and the related applications will be presented.
