# CERN Accelerating science

The theses collection aims to cover as well as possible all theses in particle physics and its related fields.
The collection starts with the thesis of Feynman, defended in 1942, and covers now alltogether more than 3000 theses. Most of the documents are held as hard copies, theses from later years are available electronically. (Note also that many theses are not physically held by the CERN Library.)

 Optimizing a Calorimetry Chamber for the RF Characterization of Superconductors / Keckert, Sebastian (Universität Siegen) ; Knobloch, Jens. (dir.) (HZB) ; Jankowiak, Andreas (dir.) (HZB) In this thesis an optimized calorimetry chamber is developed, providing at and easy mountable samples. Furthermore, it enables exchangeability of samples between the resonators at HZB and CERN. The thesis is structured as follows: First, a short introduction into SRF is given [...] CERN-THESIS-2015-339.- Siegen : Universität Siegen, 2015 Fulltext: PDF;

 Measurement of Top-Quark Pair Production Cross Sections and Calibration of the Top-Quark Monte-Carlo Mass using LHC Run I Proton-Proton Collision Data at square $\sqrt{s}= 7 and 8 TeV with the CMS Experiment. / Kieseler, Jan (DESY) ; Lipka, Ekaterina (dir.) (DESY) In this thesis, measurements of the production cross sections for top-quark pairs andthe determination of the top-quark mass are presented. Dileptonic decays of top-quarkpairs (tt) with two opposite-charged lepton (electron and muon) candidates in the ﬁnalstate are considered. [...] CERN-THESIS-?; CMS-TS-2016-007.- 2016 - 166 p.
