1. Laser-Driven Plasma Waves for Particle Acceleration and X-ray Production
Sammanfattning : This thesis presents experimental results related to laser plasma accelerators. These rely on very different principles from conventional particle accelerators. LÄS MER
2. Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme
Sammanfattning : The work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion) can be used as a local probe to sense the quantum state of a neighbouring single-ion qubit via a state-selective interaction between the readout and qubit ion.

3. Quantum computing with naturally trapped sub-nanometre-spaced ions
Sammanfattning : The main aim of this work, was to lay the foundations for the experimental realisation of a quantum mechanical controlled NOT gate in rare-earth-metal-ion-doped crystals. Small amounts of rare-earth elements, added during the growth of some inorganic crystals, will become substituted into the crystal lattice as trivalent ions. LÄS MER

5. Laser-arc treatment of aluminium alloys
Sammanfattning : The increasing use of aluminium alloys in high demand applications has lead to the development of a number of surface treatment technologies designed to improve hardness and wear characteristics. This thesis investigates the combination of a high power laser beam and an electric arc to produce new surfaces on aluminium alloys. LÄS MER
