Observation of a likely example of the decay of a charmed particle produced in a high energy neutrino interaction
Abstract In a study of neutrino interactions occurring in nuclear emulsion, an event has been found that is most readily interpreted as the decay of a charmed particle with lifetime a few times 10 −13 s.

A CMOS charge sensitive amplifier for silicon strip detectors: Design criteria and test results
Abstract A low noise charge sensitive amplifier has been developed with a commercial CMOS process. We present measurements of the amplifier's performance when used to read out a silicon strip detector exposed to a particle beam. A few prototypes have been exposed to large doses of radiation in order to study the radiation hardness.

Performance of an ARC–enabled computing grid for ATLAS/LHC physics analysis and Monte Carlo production under realistic conditions
A significant amount of the computing resources available to the ATLAS experiment at the LHC are connected via the ARC grid middleware. ATLAS ARC-enabled resources, which consist of both major computing centers at the Tier-1 level and lesser, local clusters at Tier-2 and 3 level, have shown excellent performance running heavy Monte Carlo (MC) production for the experiment. However, with the imminent arrival of LHC physics data, it is imperative that the deployed grid middlewares also can handle data access patterns caused by user-defined physics analysis. These user-defined jobs can have radically different demands than systematic, centrally controlled MC production. We report on the performance of the ARC middleware, as deployed for ATLAS, for realistic situations with concurrent MC production and physics analysis running on the same resources. Data access patterns for ATLAS MC and physics analysis grid jobs will be shown, together with the performance of various possible storage and file staging models.

The small angle tile calorimeter in the DELPHI experiment
Abstract The Small angle TIle Calorimeter (STIC) provides calorimetric coverage in the very forward region of the DELPHI experiment at the CERN LEP collider. The structure of the calorimeters, built with a so-called “shashlik” technique, gives a perfectly hermetic calorimeter and still allows for the insertion of tracking detectors within the sampling structure to measure the direction of the showering particle. A charged-particle veto system, composed of two scintillator layers, makes it possible to trigger on single photon events and provides e–γ separation. Results are presented from the extensive studies of these detectors in the CERN testbeams prior of installation and of the detector performance at LEP.

A silicon pad shower maximum detector for a "Shashlik" calorimeter
The structure of the calorimeters built with the "Shashlik" technique allows the insertion of tracking detectors within the sampling structure, in order to improve the accuracy in the determination of the showering particle direction and to enhance the e-/spl pi/ separation ability. The new luminosity monitor of the DELPHI detector at LEP was equipped with two planes of silicon pad detectors placed at a depth of 4 and 7.4 radiation lengths. A description of the silicon detectors is given, together with the results from the exposure to a test beam. >
