Local beating corrections with orbit bumps in the LHCThe purpose of this Master thesis is to explore further possibilities to increase the Luminosity of the Large Hadron Collider (LHC) by improving the optics correction. As a basic principle, the beta function describes the envelope of the beam motion if multiplied by the emittance and can be extracted from the turn-by-turn data by utilising the N-BPM method after a spectral analysis. If there are lattice imperfections, then they will perturb the beam motion and the distortion oscillates around the ring. This phenomenon is generally called beating. In order to increase the Luminosity, the beta function at the interaction point (IP) has to be reduced to a minimum. This is realised by the achromatic telescopic squeezing scheme (ATS-optics) for the High Luminosity Large Hadron Collider (HL-LHC). The disadvantage of a small beta function at the IP is a very large beta function in the triplets. Hence, any error of the magnets in the triplet causes a significant beating of the optics functions and perturbs the beta function at the IP as well. Fortunately, the triplets are powered individually, wherefore the field strengths can be adjusted separately. After applying corrections based on measurements, the distortions within the lattice are equalized as much as possible by varying the knobs. The special optics configuration of the ATS sequence also enlarges the beta function in the arcs, where the quadrupoles are powered in series. A possible correction strategy for the arcs is to use feed-downs from sextupoles by applying orbit bumps to the beam. The feasibility of this approach has been demonstrated. This Master thesis focuses on the validation of the correction method and investigates potentially degenerated orbit bumps. In addition, the measurement principle for the lattice functions is tested at the ELENA synchrotron.

Development of a test bench for the Mu3e pixel detectorAs a summer student at the University of Oxford I was affiliated with the OPMD lab. The OPMD lab provided me the unique opportunity to be part in the Mu3e collaboration. The Mu3e experiment is looking for the charged lepton flavour violation of muons and the experiment will be hosted at PSI in Switzerland. The task of the OPMD lab within the collaboration is to build the silicon-pixel modules of a low mass detector. Con- cretely, I investigated the placing accuracy of the pixel chips with the gantry. For this purpose I developed a correction strategy for systematical uncertainties by applying iterative learning control and using innovative concepts. Furthermore, I was involved in the development of a testing procedure for the Mupix chips to validate the functionality of the detector.

Analysis of tune modulations in the LHCDuring my Bachelor thesis I analyzied tune modulations in the LHC. In detail, I characterized the natural tune jitter of the LHC depending on the electromagnetic optics configuration. For this purpose, I devolped a new analysis procedure. In a nutshell, single natural tune measurements were used to perform multivariate pro- file likelihood analyses. The resulting expectation values for the parameters were used as the input of a toy Monte-Carlo study, which utilizes a modified bootstrapping sampling method. As a result, a probability den- sity distribution of the RMS-jitter of the LHC is obtained. Hence, the expectation value of the RMS-jitter as well as the corresponding uncertainty can be extracted from the pdf. The results of the thesis supported the decision process for selecting a suitable measuring scheme in the high luminosity LHC.

Apprenticeship as a physical laboratory technician
-
Sep 2009 - Feb 2013
During my vocational training at the primary laboratory of the Testo industrial services GmbH I learned the principles of metrology. The primary laboratory is responsible for calibrating the working standrards of the company. The reference devices are traced back to the standards of the Physical Technical Bundesanstalt (PTB). Physics and mathematics are the foundations of science. Hence, physical laboratory technicians need a broad knowledge in those subjects in order to be able to develop new measurement processes. Various measurement techniques are teached in several physical and chemical lab courses and the students learn different kind of crafts, like: soldering, milling and threading.
