This paper describes the AC-coupled, single-sided, pin -n silicon microstrip sensors used in the Semiconductor Tracker (SCT) of the ATLAS experiment at the CERN Large Hadron Collider (LHC). The sensor requirements, specifications and designs are discussed, together with the qualification and quality assurance procedures adopted for their production. The(More)
This paper describes the silicon microstrip modules in the barrel section of the SemiConductor Tracker (SCT) of the ATLAS experiment at the CERN Large Hadron Collider (LHC). The module requirements, components and assembly techniques are given, as well as first results of the module performance on the fully assembled barrels that make up the detector being(More)
The PICASSO experiment at SNOLAB reports new results for spin-dependent WIMP interactions on 19 F using the superheated droplet technique. A new generation of detectors and new features which enable background discrimination via the rejection of non-particle induced events are described. First results are presented for a subset of two detectors with target(More)
We report on the beamtests of ATLAS Semiconductor Tracker (SCT) modules carried out at the ATLAS testbeam facility at the CERN SPS H8 beamline during August and October 2001. In all, 16 different modules were tested including 11 pre-production barrel modules, 4 " K4 " prototype baseline endcap modules, and one " KB " prototype alternative endcap module. Of(More)
On 16 October 2012, five active radiation detectors (referred to by NASA as Radiation Environment Monitors, or REMs) employing the Timepix version of the technology developed by the CERN-based Medipix2 Collaboration were deployed on-board the International Space Station (ISS) using simple USB interfaces to the existing ISS laptops for power, control and(More)
Butyrate and isobutyrate (after isomerization to n-butyrate) are specific precursors for the biosynthesis of monensin A in Streptomyces cinnamonensis. High concentrations of both butyrate and isobutyrate (greater than 20 and 10 mM, respectively) were toxic to S. cinnamonensis plated on solid medium. Spontaneous mutants resistant to these substances were(More)
A combined approach, comprising PCR screening and genome mining, was used to unravel the diversity and phylogeny of genes encoding 5-aminolevulinic acid synthases (ALASs, hemA gene products) in streptomycetes-related strains. In actinomycetes, these genes were believed to be directly connected with the production of secondary metabolites carrying the C5N(More)
Vibrations of a slender U-profile in turbulent cross-flow are studied with the aid of 2D-CFD simulations and wind tunnel experiments. The simulations indicate that there are two different patterns of the flow around the stationary U-profile. Vor-tices form either towards the leeward flange of the profile, or behind its windward flange. The latter vortices(More)
Monensin A is a commercially important natural product isolated from Streptomyces cinnamonensins that is primarily employed to treat coccidiosis. Monensin A selectively complexes and transports sodium cations across lipid membranes and displays a variety of biological properties. In this study, we evaluated the Jacobsen catalyst as a cytochrome P450(More)
The ATLAS SemiConductor Tracker (SCT) is a silicon-strip tracking detector which forms part of the ATLAS inner detector. The SCT is designed to track charged particles produced in proton-proton collisions at the Large Hadron Collider (LHC) at CERN at an energy of 14 TeV. The tracker is made up of a central barrel and two identical end-caps. The barrel(More)
