Experiments on conversion of the PHELIX laser light into soft X-rays using a hohlraum scheme
In experiments on the conversion of the PHELIX laser light into soft X-rays, the Petawatt High-Energy Laser system for Ion beam eXperiments – “Phelix” (Nd:glass, =1054 nm) was used at the basic frequency. The chirped laser pulse of 1.4 ns duration and energies up to 270 J was focused onto the target by a lens with 4 m focal length. The diameter of the focal spot on the wall of the primer hohlra...
متن کاملThe Effect of X-rays on Glutathione
Hammctt (I), using the qualitative nitroprusside reaation, demonstrated the destruction of glutathione when water solutions were irradiated with p and y rays from radium. Woodward (2) confirmed Hammett’s observations quantitatively with radon, but failed to find any destruction with as high as 15,600 r units of Roentgen rays. She used the accurate titration method of Woodward and Fry (3) for ma...
متن کاملThe Impact of Low Level X-rays on Biosynthesis of Gold Nanoparticles by Actinobacteria
Background; Gold nanoparticles (GNPs) play an important role in medical, health and environmental applications. All kinds of microorganisms were found to be able to synthesize GNPs. The optimization of laboratory conditions for achieving more economical benefits of mass production has been studied widely. Methods;This study assesses the enhancing effect of low-level X-rays on the biosynthesis ...
متن کاملOn the X-rays of permutations
The X-ray of a permutation is defined as the sequence of antidiagonal sums in the associated permutation matrix. X-rays of permutation are interesting in the context of Discrete Tomography since many types of integral matrices can be written as linear combinations of permutation matrices. This paper is an invitation to the study of X-rays of permutations from a combinatorial point of view. We p...
متن کاملExperiments on heating of low density CHO-foams by soft X-rays
Experiments, which use a combination of the PHELIX laser kJ-option and the heavy ion beam of 4-10 MeV/u energy delivered by the UNILACaccelerator, are aimed at investigation of the heavy ion energy loss in ionized matter. In these experiments a large scale (~1mm) long living (~5ns) high density plasma target with homogeneously distributed plasma density, temperature and ionization degree is req...
