This book describes the application of a novel technology for beam instrumentation and luminosity measurement and first results on a cutting edge technology potentially to be used after the upgrade of the Large Hadron Collider to higher luminosity.

It presents a unique diamond-based luminometer with a detailed performance study.

The online bunch-by-bunch luminosity measurements provide an invaluable feedback to the Collider for beam optimisation and for the understanding of beam dynamics.

The precision of the luminosity measurement is crucial for all physics analyses. This book highlights the Van der Meer method, which is used for the calibration of the luminometers of the CMS (Compact Muon Solenoid) experiment, and describes the estimate of systematic uncertainties, e.g. due to radiation damage of sensors and electronics and uncertainties of beam parameters.

For the future high-luminosity upgrade of the collider, sapphire sensors are investigated in atest beam. It is demonstrated for the first time that sapphire sensors can be used as single particle detectors. A model for the charge transport in sapphire is developed and successfully applied.

Nominated as an outstanding Ph.D thesis by DESY, Germany Offers a cutting-edge technology for beam instrumentation and luminosity measurement Presents a unique diamond-based luminometer with detailed performance description Proposes an alternative detector material to lower the costs of the experiment

Autorentext

Olena Karacheban was born in the small city of Izmail in Ukraine. Following school she entered Kiev National University, where she received a bachelors and then a masters degree. Thanks to her university supervisor and the collaboration with DESY and Fermilab she was able to gain work experience on major physics experiments whilst still a student. Her dreams were realized when she started the PhD program at the Brandenburgische Technical University, Cottbus, supported by a grant from the German-Israel Foundation, and thence she began her career at CERN.
