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 کاملInfluence of UV-light on gene-conversion in Neurospora.
1. Crosses between wild type (dark ascospores) and the asco-mutant (light ascospores) were set up and the spores collected as unordered octads. The analysis of 1317 such octads revealed 69 with abnormal segregation of the asco-marker (5.2%). If crosses were irradiated with UV at a dose equivalent to 66% conidial killing, an increase of the number of aberrant octads was found. This increase was ...
متن کاملConversion of HOL Light proofs into Metamath
We present an algorithm for converting proofs from the OpenTheory interchange format, which can be translated to and from any of the HOL family of proof languages (HOL4, HOL Light, ProofPower, and Isabelle), into the ZFC-based Metamath language. This task is divided into two steps: the translation of an OpenTheory proof into a Metamath HOL formalization, hol.mm, followed by the embedding of the...
متن کاملForward Elastic Scattering of Light on Light , γ + γ → γ + γ
The forward elastic scattering of light on light, i.e., the reaction γ + γ → γ + γ in the forward direction, is analyzed utilizing real analytic amplitudes. We calculate ργγ , the ratio of the real to the imaginary portion of the forward scattering amplitude, by fitting the total γγ cross section data in the high energy region 5 GeV ≤ √ s ≤ 130 GeV, assuming a cross section that rises asymptoti...
متن کاملComparative study of TL created in undoped CVD diamond by rays, UV and visible light
The thermoluminescence (TL) properties of CVD diamond film irradiated with b rays and illuminated with UV and visible light (200–450 nm) have been studied. The film (23mm) was grown for 47 h on monocrystalline silicon. The TL glow curves are similar for b irradiation and short wavelength UV light. The b dose response curves and UV light time response curves exhibit linear–supralinear–sublinear ...
