The dipole strength of the nuclide Zn66 was studied in photon-scattering experiments using bremsstrahlung produced with electron beams energies 7.5 and 13.4 MeV at γELBE facility as well quasimonoenergetic linearly polarized photon 30 within range 4.3 to 9.9 HIγS facility. A total 128 J=1 states were identified, among them 9 1+ 86 1− assignments. quasicontinuum unresolved transitions included analysis spectra intensities branching estimated on basis simulations statistical γ-ray cascades.

High energy attosecond electron bunches from the laser-plasma wakefield accelerator (LWFA) are potentially useful sources of ultra-short duration X-rays pulses, which can be used for ultrafast imaging motion in biological and physical systems. Electron injection LWFA depends on plasma density gradient, laser intensity. Recent research has shown that is possible using a short ramp. For controlled it necessary to keep both intensity background constant, but set just below threshold injection....
It is suggested that the combined effect of a resonant magnetic field (dynamic Zeeman effect) and fluctuations due to spin-spin spin-lattice interactions could give rise inelastic components in emission spectrum paramagnetic system. also shown similar can be expected second harmonic emission. found if Rabi frequency much larger than relaxation rates, both spectra show two side lines typical atomic fluorescence. The results are illustrated by means semiclassical model. Plots as function given...
With the increase of laser power at facilities reaching petawatt-level, there is a need for accurate electron beam diagnostics wakefield accelerator (LWFA), which are becoming important tools wide range applications including high field physics. Electrons in several 100s GeV expected these levels. Precise diagnostic systems required to enable such as advanced radiation sources. Accurate measurement energy spread beams will help pave way towards LWFA based free-electron lasers and plasma...

Abstract Laser wakefield accelerators (LWFAs) are promising sources of high brightness particle and radiation beams with many possible applications, ranging from scientific research to medicine, industry border security. The Scottish Centre for the Application Plasma-based Accelerators (SCAPA) is a university-based facility employing use two high-power, ultrashort pulse lasers advance research, development application laser-plasma accelerators. Here we report on recent advancements in LWFA...
Abstract Isotopes for nuclear medicine are scarce and expensive. Researchers worldwide exploring new production methods to avoid the dependence on reactors as sources satisfy future isotope demands. Photo-nuclear reactions have hitherto been used a tool studying structure. Laser wakefield accelerators (LWFAs) very compact capable of producing high energy electron beams. In this paper we investigate possibility using LWFAs produce 225 Ac via photo-spallation reactions.
Here we explore ways of transforming laser radiation into incoherent and coherent electromagnetic using laserdriven plasma waves. We present several examples based on the wakefield accelerator (LWFA) show that electron beam from LWFA has unique characteristics compared with conventional devices. energy spread can be much smaller than 1% at 130-150 MeV. This makes LWFAs useful tools for scientists undertaking time resolved probing matter subject to stimuli. They also make excellent imaging...
