Investigation into the mechanical response and microstructure evolution of high density polyethylene, under conditions applicable to the injection stretch blow moulding process
… x-rays analysis techniques carried out at Diamond Light Source. The results indicated that the deformation proceeded via fragmentation and recrystallisation. Furthermore, the initial crystallinity of 56% was reduced to 32% after heating and then, was further reduced to 20% immediately after …

3D detectors for synchrotron applications
… diffraction measurements at synchrotrons such as Diamond Light Source. This would allow these experiments, for example, to determine the structures of biological molecules more accurately. However, before 3D devices can be used in practical experiments, their design and fabrication must be …

Development of Serial Crystallography Methods for Synchrotrons and X-ray Free-Electron Lasers
… collection and processing strategies, applied at Diamond Light Source microfocus beamline I24, and at BL3 EH2 at the SACLA XFEL, Japan. A technique coined ‘multiple serial structures’ (MSS) has been developed and used in this thesis to assess how crystalline proteins change as a function of X-ray …

Serial and Single Crystal Studies of Ligand Binding to Radiation Sensitive Haem Protein DHP-B
… results. Single crystal data were obtained from Diamond Light Source (DLS) and Swiss Light Source, or from the protein data bank. Crystals were grown using the hanging-drop vapour diffusion method, soaked in cryoprotectant and measured at synchrotron sources. Serial data was collected using …

Interfaces between two-dimensional transition metal dichalcogenide semiconductors and oxide dielectrics for transistors
… using hard and soft X-ray photoemission at Diamond Light Source. Using X-Ray Photoelectron Spectroscopy (XPS) complemented by Raman and photoluminescence (PL) spectroscopies, it is shown that common gate oxides such as SiO₂ and HfO₂ strongly dope 2D MoS₂ and other 2D TMDs. XPS shows …

The thermal stability of bulk nanocrystalline steels
… the Deutsches Elektronen Synchrotron (DESY) and Diamond Light Source. The high-quality data that were collected allowed the symmetry of the ferrite lattice to be investigated and it was found that the lattice was best-described using a body-centred tetragonal crystal structure. This is the first …

Application of precision engineering for nanometre focussing of hard X-rays in synchrotron beam lines
Many modern synchrotron beamlines are able to focus X-rays to a few microns in size. Although the technology to achieve this is well established, performing routine experiments with such beams is still time consuming and requires careful set up. Furthermore there is a need to be able to carry out …

Emergent Critical Phases in Strongly Correlated Low-Dimensional Magnetic Systems
… both single crystal and powder samples at the Diamond Light Source. Although FePSe<sub>3</sub> shares a similar intraplanar configuration with FePS<sub>3</sub>, it exhibits differences in interplanar stacking at both ambient and elevated pressures. Pressure-induced superconductivity has only …

A study of multipacting in rectangular waveguide geometries
… that are used in a number of synchrotron light sources including the DIAMOND Light Source, have had a history of vacuum breakdown in the CESR ring at Cornell with frequencies that would be inappropriate for a reliable synchrotron facility. This work aims to understand and correct the …
