With the LHC operation at 6.5 TeV and with 25 ns bunch spacing after LS1, the understanding and control of beam instabilities in 2015 has become at least as challenging as during Run 1 and a crucial point to be followed to guarantee a smooth intensity ramp up. As expect...

The Compact Muon Solenoid (CMS) detector installed at the CERN Large Hadron Collider (LHC) has an extensive muon system which provides information simultaneously for identification, track reconstruction and triggering of muons. As a consequence of the extreme particle r...

ADCs and DACs are crucial components in the relentless drive to replace analog circuitry with more controllable and less costly digital processing. This paper reviews the technologies available for measurement and control as applied to accelerators. It covers much of th...

We search for the Standard Model(SM) Higgs boson in the two photon decay channel (H\rightarrow \gamma \gamma), produced in pp-collisions at a center-of-mass energy of 7TeV with the ATLAS detector at the LHC. The search is performed for the Higgs mass range between 110 a...

The calculation of missing transverse momentum (ETmiss) has been and will continue to be vital for physics analyses at the ATLAS experiment. Quantifying the momentum imbalance of the event gives physicists the ability to identify non-interacting standard model particles...
