Afa, Iduabo John (Date of defense: 2018-01-24)

Control is important for transferring theoretical scientific knowledge into practical technology for applications in numerous fields. This is why coherent control study is significant on every timescale to have a complete ...

Understanding secondary emission processes and beam matter interactions for optimization of diagnostic wire grid system in particle accelerators : thermal modeling for beam power limits calculation

Navarro Fernández, Araceli (Date of defense: 2023-03-21)

(English) Thin targets, in form of foils, stripes or wires, are widely used in beam instrumentation to measure various beam parameters, such as intensity, position and size. All these monitors can differ in geometry and ...

World-wide analysis and modelling of the ionospheric and plasmaspheric electron contents by means of radio occultations

Shao, Yixie (Date of defense: 2019-02-25)

The research of this dissertation is studying the ionosphere by GPS radio occultation (RO) techniques. It is mainly divided into two parts. The first part focuses on the methodology in electron density profile retrievals ...
