Measurement of elastic proton-proton scattering at $\sqrt{s} = 7$ TeV with the ALFA sub-detector of ATLAS at the LHC

The ATLAS experiment with the ALFA sub-detector, provides a unique opportunity to measure elastic proton–proton scattering at the LHC at a centre-of-mass energy of √ s = 7 TeV, that has never been

Search for the Production of a Standard Model Higgs Boson in Association with Top-Quarks and Decaying into a Pair of Bottom-Quarks with 13 TeV ATLAS Data

This thesis presents the search for the Standard Model Higgs boson produced in association with a pair of top-quarks (tt̄H). The analysis uses a 36.1 fb−1 dataset of proton-proton collisions at a

Proton-Proton Central Exclusive Pion Production at $\sqrt{13}$ TeV with the ALFA and ATLAS Detector

The cross section for proton-proton central exclusive dipion production, pp→ p+π+π−+ p, has been measured at the center of mass energy √ s = 13TeV, where double Pomeron exchange is expected to

A scintillating fibre beam profile monitor for the experimental areas of the SPS at CERN

The CERN Super Proton Synchrotron (SPS) delivers a wide spectrum of particle beams (hadrons, leptons and heavy ions) that can vary greatly in momentum and intensity. The profile and position of these

The ALFA Roman Pot detectors of ATLAS

The ATLAS Roman Pot system is designed to determine the total proton-proton cross section as well as the luminosity at the Large Hadron Collider (LHC) by measuring elastic proton scattering at very



The DAQ for the EUDET pixel telescope

The DAQ system presented is platform independent, lightweight but scalable and outputs data as lcio streams for the ILC software framework.

Online luminosity monitoring with liquid Argon calorimeters at ATLAS and D0

This note discuss a luminosity monitoring method for the high energy hadron colliders Tevatron and LHC, based on the measurement of the high voltage current of liquid Argon calorimeters. This method

Absolute luminosity from machine parameters

The expected rates for proton proton collisions in the LHC are rather high. Monitoring can be based on several detector components and different physics channels can be used together and should allow

Basic Considerations on the Overlap Detectors of the ATLAS ALFA system

We discuss the motivation and possible implementation of Overlap Detectors for the relative alignment of the two halves of the ATLAS Roman Pot detectors. We propose a system design and a set of

Beam-induced heating / bunch length / RF and lessons for 2012

The observations made in 2011 in the LHC are first compared to expectations and the possible implications for the operation in 2012 are then discussed.

Energy Calibration of the LHC Beams at 4 TeV

The mixed proton and lead ion run in January and February 2013 (p-Pb run) provided an excellent opportunity to measure the beam energy at the LHC. The beam energy of the LHC was determined at 4 TeV
