1. 11. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

   University essay from Uppsala universitet/FREIA

   Author : Karl-Fredrik Boholm Kylesten; [2023]
   Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

   Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

3. 12. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Paul Böhm; [2023]
   Keywords : re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

   Abstract : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.

4. 13. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Laura Karina Pedraza Motavita; [2023]
   Keywords : Technology and Engineering;

   Abstract : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. READ MORE

5. 14. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

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

   Author : Saga Westerberg; [2023]
   Keywords : Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

   Abstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index.

6. 15. Investigation of Ion Extraction Anomalies at TwinEBIS

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Niek van Woudenberg; [2023]
   Keywords : CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

   Abstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE
