1. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.

2. Magnetic nozzle plume plasma simulation through a Particle-In-Cell approach in a 3-D domain for a Helicon Plasma Thruster. : A collaboration with REGULUS project T4i Technology for Propulsion and Innovation s.p.a.
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Recent advances in plasma-based propulsion systems have led to the development of electromagnetic Radio-Frequency (RF) plasma generation and acceleration systems, called Helicon Plasma Thrusters (HPT). One of the pioneer companies developing this new type of space propulsion is T4i Technology for Propulsion and Innovation s.p.a. LÄS MER
3. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : In the last 30 years, numerical models have been developed to properly analyze Hall eect thrusters (HET),leading to a bridge between analytical prediction/empirical intuition and experiments. For companies in thespace sector, these codes serve to much more than simply simulating the thruster, but it provides a fast, cheapand reliable tool for processes such as validation and verication procedures, as well as for technical developmentof the thruster.

4. Evolution of the signal induced by ChemCam on Mars as a function of focus
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : ChemCam, mounted on the mast of the Mars Science Laboratory (MSL) rover, uses Laser-Induced Breakdown Spectroscopy (LIBS) to perform remote-sensing science on Mars. ChemCam’s telescope is used to simultaneously focus the laser on martian rocks up to 7 meters away from the rover and collect the light emitted as the plasma plume created on the target cools down.

5. Investigation of the electron density close to the rings of Saturn and Prediction of the F-ring plasma characteristics
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : Saturn has the second strongest magnetic field among the planets of the solar system, creating the second biggest magnetosphere, after Jupiter. The magnetosphere is similar to Earth's, as both of them are created by a dipole magnetic field, produced by a planetary dynamo. Despite the similarities, they have some major differences. LÄS MER
