Bachelor Theses

The BCM1F detector at the CMS experiment is responsible for the measurement of theluminosity, as well as the beam-induced background. It is assumed that the sensors will haveto be replaced during Run 3 of the LHC, which is why work is already underway to build areplacement system [...]

Diese Bachelorthesis umfasst die Änderungskonstruktion einer verkürzten Variante eines 5m-Undulators unter Berücksichtigung des Magnetträger-Verformungsverhaltens.Die Magnetträger sind symmetrisch, maximal zu kürzen. Alle weiteren Komponenten sollen möglichst unverändert bleiben. [...]

In this thesis a nano-electrospray ionization source gets developed. Since nano-electrosprayionization has an increasing importance for single particle imaging we want to optimizethe developed nano-electrospray ionization source for single particle imaging applica-tion. [...]

Aligning the gratings of an optical compressor for femtosecond pulses, as used inchirped pulse amplification, is a nontrivial task. In order to simplify this task a portabletunable continuous-wave laser, with automated wavelength tuning, was designed, constructedand automated. [...]

The Free Electron Laser in Hamburg FLASH provides short X-Ray and ultraviolet pulses with high repetition rates in bursts. Optical laser systems create synchronized bursts in various wavelength ranges for pump-probe-experiments. [...]

Filamentous fungi are fo high biotechnological interest. Their fermentation products can beused for producig various goods. [...]

In this thesis, a new method of performing total X-ray scattering measurements of photo-electrochemically (PEC) active CuBi2O4 thin-films in operando was investigated. The thin-films were fabricated via spin-coating of a precursor solution containing Cu and Bi ions onto an FTO-coated glass substrate. [...]

Obwohl etwa 85% der gesamten Materie im Universum aus Dunkler Materie besteht (vgl.Eidemüller 2017: 5), ist ihre Natur bisher noch ungeklärt. Lediglich die Gravitationswirkung, die Dunkle Materie auf sichtbare Materie zu hab en scheint, ist erwiesen. [...]

Laser beam induce current (LBIC) and X­ray beam induced current (XBIC) are effective tech­niques for mapping the spatial electrical performance of solar cells. Conducting precise currentmeasurements up to the femto­Ampere range is challenging and susceptible to noise [...]
