Physics-based flow visualization techniques seek to mimic laboratory flow visualization methods with virtual analogues. In this work we describe the rendering of a virtual rheoscopic fluid to produce images with results strikingly similar to laboratory experiments with real-world rheoscopic fluids using products such as Kalliroscope. These fluid additives(More)
We present an end-to-end optimization of the innovative Arbitrary high-order DERivative Discontinuous Galerkin (ADER-DG) software SeisSol targeting Intel<sup>&#174;</sup> Xeon Phi<sup>&#8482;</sup> coprocessor platforms, achieving unprecedented earthquake model complexity through coupled simulation of full frictional sliding and seismic wave propagation.(More)
SUMMARY The main theme of this paper is the modelling error associated with the choice of constitutive equations and associated parameter sensitivity. These key concepts are ÿrst discussed in a general way and explored in detail subsequently for three ow application problems which share certain similarities not only in the ÿnite element formulation but also(More)
The heavy ion trap facility (HITRAP), which is shown in fig.1 and is being built in the re-injection channel between ESR and SIS will provide unique beams of highly charged ions up to bare uranium at very low energies for a large variety of experiments. At the HITRAP facility the ions, produced by the GSI accelerator facility, will be decelerated in two(More)
During the beam time in 2003 a carbon beam from the ECR ion source was mainly accelerated via the high charge state injector (HLI) in the UNILAC for the SIS-injection like in the years before [1]. Several UNILAC experiments used the beam with high duty factor additionally. Additionally, the ECR source was in operation for the production of various isotopes(More)
The new 1.4 MeV/u front end HSI (HochStromInjektor) of the Unilac accelerates ions with A/q ratios of up to 65 and with beam intensities in emA of up to 0.25 A/q. The maximum beam pulse power is up to 1300 kW. During the stepwise linac commissioning from April to Septem-ber 1999 the beam behind of each cavity was analysed within two weeks. A very stable Ar(More)
At present 3 prototype CH-cavities are under design and / or construction at velocity ranges from β = 0.05 up to β = 0.45 to further improve and explore the capabilities of that novel type of multi-cell superconducting cavity. A 325 MHz, 7 cell, β = 0.15 CH-cavity has been designed and is currently under construction at Research Instruments (see fig. 1)[1].(More)
