- The first results from the Stopped Beam RISING experimental campaign performed at the GSI laboratory in Darmstadt, Germany, are presented. RISING (Rare ISotope INvestigations at GSI) constitutes a major new experimental program in European nuclear structure physics research aimed at using relativistic‐energy, projectile‐fragmentation reactions to study nuclei with exotic proton‐to‐neutron ratios. This paper introduces the physics aims of the Stopped RISING collaboration and presents some technical details and initial results from experiments using the RISING array to study decays from metastable nuclear states in both proton and neutron‐rich nuclei.

Konferensbidrag (refereegranskat)abstract
- In the last couple of years, many e-Science infrastructures have begun to offer production services to e- Scientists with an increasing number of applications that require access to different kinds of computational resources. Within Europe two rather different multi-national e-Science infrastructures evolved over time namely Distributed European Infrastructure for Supercomputing Applications (DEISA) and Enabling Grids for E-SciencE (EGEE). DEISA provides access to massively parallel systems such as supercomputers that are well suited for scientific applications that require many interactions between their typically high numbers of CPUs. EGEE on the other hand provides access to a world-wide Grid of university clusters and PC pools that are well suited for farming applications that require less or even no interactions between the distributed CPUs. While DEISA uses the HPC-driven Grid technology UNICORE, EGEE is based on the gLite Grid middleware optimized for farming jobs. Both have less adoption of open standards and therefore both systems are technically non-interoperable, which means that no e-Scientist can easily leverage the DEISA and EGEE infrastructure with one suitable client environment for scientific applications. This paper argues that future interoperability of such large e-Science infrastructures is required to improve e-Science in general and to increase the real scientific impact of world-wide Grids in particular. We discuss the interoperability achieved by the OMII-Europe project that fundamentally improved the interoperability between UNICORE and gLite by using open standards. We also outline one specific scientific scenario of the WISDOM initiative that actually benefits from the recently established interoperability.

Monolithic Bidirectional Switch (MBS) - A novel MOS-based power device
- 2005
-
Ingår i: PROCEEDINGS OF ESSDERC 2005. - 0780392035 ; , s. 473-476

Konferensbidrag (refereegranskat)abstract
- A novel MOS-based power device, the Monolithic Bidirectional Switch (MBS), is investigated in this work. An analytical model is used to explain basic device operating principles. A self-aligned fabrication process of lateral MBS devices with Schottky contacts and local oxidation of silicon technique (LOCOS) is described. Experimental results are compared with the analytical model to analyze the influence of device parasitics. Bidirectional switching and an on/off-current ratio of more than 100 is demonstrated for MBS devices for the first time.

Open standards-based interoperability of job submission and management interfaces across the grid middleware platforms gLite and UNICORE
- 2007

Ingår i: Proceedings - e-Science 2007, 3rd IEEE International Conference on e-Science and Grid Computing. - : IEEE Computer Society. - 0769530648 - 9780769530642 ; , s. 592-599

Konferensbidrag (refereegranskat)abstract
- In a distributed Grid environment with ambitious service demands the job submission and management interfaces provide functionality of major importance. Emerging e-Science and Grid infrastructures such as EGEE and DEISA rely on highly available services that are capable of managing scientific jobs. It is the adoption of emerging open standard interfaces which allows the distribution of Grid resources in such a way that their actual service implementation or Grid technologies are not isolated from each other, especially when these resources are deployed in different e-Science infrastructures that consist of different types of computational resources. This paper motivates the interoperability of these infrastructures and discusses solutions. We describe the adoption of various open standards that recently emerged from the Open Grid Forum (OGF) in the field of job submission and management by well-known Grid technologies, respectively gLite and UNICORE. This has a fundamental impact on the interoperability between these technologies and thus within the next generation e-Science infrastructures that rely on these technologies.
