The ITER divertor design is the culmination of years physics and engineering effort, building confidence that this critical component will satisfy requirements meet challenge burning plasma operation. With 54 cassette assemblies, each weighing ∼9 tonnes, nearly 3900 actively cooled high heat flux elements rated to steady-state surface power densities 10 MW m−2 a total ∼60 000 carbon fibre composite monoblocks ∼260 tungsten monoblocks/flat tiles, be largest most advanced its kind ever...
The paper describes the results of a physics analysis modified divertor cassette for ITER. issues addressed are impact on operational window, effect gas leaks through broader gaps between cassettes and radiation power loading different components cassettes. shows that new design ensuring more flexibility ITER operation remains acceptable within framework usual trade-off target helium removal efficiency. load side walls structures in inter-cassette is identified as constraint not previously...
The full tungsten divertor qualification program was defined for the R&D activity in domestic agencies. consists of two steps: (i) technology development and validation (ii) a full-scale demonstration. Small-scale mock-ups were manufactured Japanese European industries delivered to ITER test facility Russia high heat flux testing. In parallel program, both agencies demonstrated that W monoblock technologies withstanding up 20 MW m−2 available.
The goal of the DIRAC experiment at CERN (PS212) is to measure $\pi^+\pi^-$ atom lifetime with 10% precision. Such a measurement would yield precision 5% on value $S$-wave $\pi\pi$ scattering lengths combination $|a_0-a_2|$. Based part collected data we present first result lifetime, $\tau=[2.91 ^{+0.49}_{-0.62}]\times 10^{-15}$ s, and discuss major systematic errors. This corresponds $|a_0-a_2|=0.264 ^{+0.033}_{-0.020} m_{\pi}^{-1}$.
In September 2011, the ITER Organization (IO) proposed to begin operation with a full-tungsten (W) armoured divertor, objective of taking decision on final target material (carbon fibre composite or W) by end 2013. This period 2 years would enable development full-W divertor design compatible nuclear operations, investigation further several physics R&D aspects associated use W targets and completion technology qualification. Beginning brief overview reference heat load specifications which...
The DIRAC experiment at CERN has achieved a sizeable production of $\pi^+\pi^-$ atoms and significantly improved the precision on its lifetime determination. From sample 21227 atomic pairs, 4% measurement S-wave $\pi\pi$ scattering length difference $|a_0-a_2| = (.0.2533^{+0.0080}_{-0.0078}|_\mathrm{stat}.{}^{+0.0078}_{-0.0073}|_\mathrm{syst})M_{\pi^+}^{-1}$ been attained, providing an important test Chiral Perturbation Theory.
We report on measurements of the differential cross section $d\ensuremath{\sigma}/d\mathrm{\ensuremath{\Omega}}$ and first measurement analyzing power ${A}_{y}$ in $\mathrm{\ensuremath{\Delta}}(1232)$ excitation energy region reaction $pp\ensuremath{\rightarrow}{{pp}}_{s}{\ensuremath{\pi}}^{0}$ where ${{pp}}_{s}$ is a $^{1}S_{0}$ proton pair. The experiment has been performed with ANKE spectrometer at COSY-J\"ulich. data reveal peak dependence forward section, minimum zero degrees its...
The ITER divertor, in its full-power operation phase, will need to withstand steady-state heat fluxes of up 10 MW•m−2. In addition, "slow" plasma transients such as re-attachment events must be considered, during which the surface increase significantly a short period time (∼few seconds). To mitigate transients, plans use divertor gas injection system (GIS) introduce radiating impurity species (probably using hydrogenic carrier improve response time) into plasma. We consider here various...
The vector and tensor polarizations of a deuteron beam have been measured using elastic deuteron-carbon scattering at 75.6 MeV deuteron-proton 270 MeV. After acceleration to 1170 inside the COSY ring, deuterons were checked by studying variety nuclear reactions cluster target ANKE magnet spectrometer placed an internal position storage ring. All these measurements consistent with absence depolarization during provide number secondary standards that can be used in subsequent experiments facility.
