Abstract Large scale experiments at CERN’s Hadron Collider (LHC) rely heavily on computer simulations (CSs), a fact that has recently caught philosophers’ attention. CSs obviously require appropriate modeling, and it is common assumption among philosophers the relevant models can be ordered into hierarchical structures. Focusing LHC’s ATLAS experiment, we will establish three central results here: (a) with some distinct modifications, individual components of ATLAS’ overall simulation...
In this paper it is shown that a measurement of the relative luminosity changes at LHC may be obtained by analysing currents drawn from high voltage power supplies electromagnetic section forward calorimeter ATLAS detector. The method was verified with reproduction small using proton beams known beam energies and variable intensities U-70 accelerator IHEP in Protvino, Russia. experimental setup data taking during test run April 2008 are described detail. A comparison measured reference...
One of the main challenges for ATLAS ITk Phase II Pixel upgrade is low-mass efficient power distribution detector modules. This requires a powering scheme alternative to parallel (direct) which currently used. A serial has been chosen as baseline pixel system. serially powered prototype built with all components that are needed current distribution, data transmission, bypassing and redundancy in order prove feasibility implementing ITk. Detailed investigations electrical performance equipped...
The ATLAS collaboration will install a new inner tracker (ITk) during the phase II upgrade. innermost part be pixel detector. A Detector Control System (DCS) is being developed to provide control and monitoring of ITk MoPS CANopen based Application Specific Integrated Circuit foreseen independently monitor serial power chain. final chip required radiation hard up an ionizing dose 500 Mrad. This paper focuses on feasibility combining low supply voltage custom ASICs found in detection...
A common task in scientific computing is the data reduction. This workflow extracts most important information from large input and stores it smaller derived objects. The objects can then be used for further analysis. Typically, these workflows use distributed storage resources. straightforward setup of media would low-cost tape higher-cost disk storage. large, infrequently accessed are stored on smaller, frequently In a best-case scenario, only very well-planned pattern. However, practice...
The upgrade of the LHC to HL-LHC requires a new ITk detector. innermost part this tracker is pixel University Wuppertal developing DCS monitor and control current concept envisions three parallel paths DCS. first path, called security hardwired provides an interlock system guarantee safety detector human beings. second path path. This used supervise entire has its own communication lines independent from regular data readout for reliable operation. third diagnostics information on demand. It...
In the context of LHC upgrade to HL-LHC inner detector ATLAS experiment will be replaced completely. As part this redesign there also a new pixel detector. This requires control system which meets strict space requirements for electronics in experiment. To accomplish goal we propose DCS (Detector Control System) network with smallest form factor currently available. consists chip located close proximity interaction point and controller outer regions These two types chips star shaped several...
In terms of the phase-2 upgrade ATLAS detector, entire inner tracker (ITk) will be replaced. This includes pixel detector and corresponding control system (DCS).

In addition, irradiation introduced.
This paper argues against the claim that high-energy physics experiments done so far could not be carried out without computer simulations. We show it would possible to completely dispense with simulations for conducted date, and up now are mostly used practical reasons. Our investigation covers all elements of experimental research in which have been used. Dispensing yield an advantage regard complex theory dependence experiments. also point may play a more essential role measurements...

The University Wuppertal developing concept DCS (Detector Control System) network consisting two kinds ASICs....
The optical links for the ATLAS Pixel detector has been passed several steps of development. After design and production components itself, various tests have performed on individual smaller or larger parts full system. Finally, were commissioned in situ after installation. A lot experience gained this should be used to step into research future but also other detectors. In paper procedure commissioning work link observed issues system layout function are discussed brought an outlook designs.
We announce the forthcoming public release of Version 1.1 MGGPOD, a user-friendly suite Monte Carlo codes built around widely used GEANT (Version 3.21) package.
