Tracking and Tolerances Study for the Atlas High-beta Optics
نویسندگان
چکیده
For luminosity and proton-proton total cross section measurement, the standard LHC Physics optics has been modied for the ATLAS experiment in the so-called High Beta optics with β*=2625 m. The high beta optics takes into account the whole LHC ring. Protons are tracked from the interaction point to the detectors. Tolerances on the β* are given and the effect of misalignment errors is checked. We show the impact of the misalignment on the measurement.

متن کاملMeasuring Elastic Scattering in the Coulomb Nuclear Interference (CNI) Region in ATLAS – Total Cross Sections and Luminosity
The Large Hadron Collider (LHC) will provide proton-proton collisions for the experiments installed at the interaction points (IP). The ATLAS detector is designed to detect high pt reactions and will focus on the discovery of the Higgs boson and new physics. However ATLAS is now also complemented by detectors in the very forward region to measure small angle elastic scattering. This will give a...

In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...
متن کاملStudy of the NLC Linac Optics Compatible with a Low Energy Scenario 1
We explore the NLC linac optics compatible with a low energy scenario where initially only part of the full linac is installed. Optics modification suitable for a low energy beam running and upgrade to the nominal energy is discussed. Linac parameters and beam tolerances in the modified lattice are compared to the nominal design. Abstract We explore the NLC linac optics compatible with a low en...
