1. 1. Comprehensive Venus boundaries model : Empirical dependency of boundaries on the upstream conditions

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Umberto Rollero; [2023]
   Keywords : Bow shock; Ion Composition Boundary; Venus; Upstream conditions; Solar wind.; Bow shock; Bogshock; Ion Composition Boundary; Venus; Uppströmsförhållanden; Solvind.;

   Abstract : Since Venus is an unmagnetized planet, it doesn’t interact with the solar wind in the same way as planets with an intrinsic magnetic field do. Due to its conductive ionosphere, however, it still possesses an induced magnetosphere. READ MORE

3. 2. Improving the understanding of photoelectron currents on Solar Orbiter : Utilizing theory and empirical measurements

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Melker Marminge; [2023]
   Keywords : Solar Orbiter; Photoelectric Currents; Photoelectric Effect; Thermal Bending; Outgassing; Thermionic Emission; Numerical Approximation; Physical Modeling;

   Abstract : Spacecraft experience electric currents on conductive materials exposed to sunlight, which introduces noise in scientific data. These currents are mainly due to the photoelectric effect and should therefore be proportional to the inverse square heliocentric distance. READ MORE

4. 3. Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flares

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Sofia Tynelius; [2022]
   Keywords : Solar flares; the Sun; STIX; EUI; alignment; pointing;

   Abstract : Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). READ MORE

5. 4. Synchrotrons as a Source for Soft X-Ray Lithography

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Thomas Joseph Grandsaert Jr; [2021]
   Keywords : Physics and Astronomy;

   Abstract : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

6. 5. Offline study of next generation EUV pellicle materials and performances : From experimental design to material characterization

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Susanna Licheri; [2019]
   Keywords : Semiconductors; Nanotechnology; EUV Lithography; EUV Pellicle; Qualification study; Halvledare; nanoteknik; EUV litografi; EUV Pellicle; kvalificerings studie;

   Abstract : Lithography is the most crucial step in the semiconductor microfabrication workflow. Continuous features size shrinking co-occurs with the reduction of the exposure wavelength: a move from 193 nm light to extreme ultra-violet (EUV) at 13.5 nm is performed. The change poses a vast number of challenges that have been overcome in the past years. READ MORE
