A compact high-current 50 kV ion accelerator facility including a windowless gas target system, beam calorimeter, and detector telescopes in close geometry has been built tested. The data acquisition analysis involved multiparameter system Monte Carlo program. LUNA facility, presently installed at the Gran Sasso underground laboratory, is pilot project focused initially on cross section measurements of 3He(3He, 2p)4He reaction within thermal energy region sun. To achieve this goal,...
As the LHC luminosity is ramped up to 3 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">$\,\times 10^{34}~{\hbox {cm}}^{2}~s^{1}$</tex></formula> and beyond, high rates, multiplicities, energies of particles seen by detectors will pose a unique challenge. Only tiny fraction produced collisions can be stored offline immense real-time data reduction needed. An effective trigger system must maintain...
This paper describes the electronics used for ATLAS monitored drift tube (MDT) chambers. These chambers are main component of precision tracking system in muon spectrometer. The MDT detector consists 1,150 containing a total 354,000 tubes. It is capable measuring sagitta tracks to an accuracy 60 μm, which corresponds momentum about 10% at pT= 1 TeV. design and performance readout as well controlling, monitoring powering will be discussed. have been extensively tested under simulated running...
The New Small Wheel (NSW) is an upgrade for the ATLAS detector to provide enhanced triggering and reconstruction of muons in forward region. large LV power demands NSW necessitate a point-of-load architecture with on-detector conversion. radiation load magnetic field this environment, while significant, are nevertheless still range where commercial-off-the-shelf devices may suffice.
The paper describes power switching converters suitable for possible supply distribution networks the upgraded detectors at High Luminosity LHC collider. proposed topologies have been selected by considering their tolerance to highly hostile environment where will operate as well limited electromagnetic noise emission. analysis focuses on description of supplies noble liquid calorimeters, such Atlas LAr though several outcomes this research can be applied other future experiments....
Prototypes of DC/DC power and Point Load (PoL) converters were designed built with the aim satisfying foreseen working parameters High Luminosity (HL) LHC experiments, using both Silicon (Si) MOSFETs and/or more recent devices substantiated better performance, like Carbide (SiC) Gallium Nitride (GaN) transistors. Optimization their design, based on comparison between simulated measured thermal, electrical mechanical is in progress, many improvements respect to previous versions are under...
This paper investigates the use of switching converters for power supply distribution to calorimeters in ATLAS experiment when Large Hadron Collider (LHC) will be upgraded beyond nominal luminosity. Due highly hostile environment must operate in, all main aspects are considered investigation, from selection converter topologies thermal analysis components and PCBs, with attention reliability issues devices subject ionizing radiations. The focuses on particular, but crucial, case supplies...
Modern experiments search for extremely rare processes hidden in much larger background levels. As the experiment`s complexity, accelerator backgrounds and luminosity increase we need increasingly complex exclusive event selection. We present first prototype of a new Processing Unit (PU), core FastTracker processor (FTK). FTK is real time tracking device ATLAS trigger upgrade. The computing power PU such that few hundred them will be able to reconstruct all tracks with transverse momentum...
The Fast TracKer (FTK) is an extremely powerful and very compact processing unit, essential for efficient Level 2 trigger selection in future high-energy physics experiments at the LHC. FTK employs Associative Memories (AM) to perform pattern recognition; input output data are transmitted over serial links Gbit/s reduce routing congestion board level. Prototypes of AM chip have been manufactured tested, preparation imminent design final version.
The reliability of a power converter can be improved using well-dimensioned cold plate. For this purpose, it is necessary to realize state-of-the-art plate by means thermal-fluid dynamic numerical analysis and an ad hoc experimental test bench. Features metrological characterization bench for are discussed in paper. An infrared camera used measure the outer surfaces, thermocouples employed temperatures some inner points, but not all points structure under accessible probes sensing. accurate...
