1. 1. The Channeling Effect in Ultra-Thin dE-E Monolithic Silicon Telescopes

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Författare :Fredrik Parnefjord Gustafsson; [2017]
   Nyckelord :dead-layer; Channelling; The Channeling effect; Plasma effect; Nucleosynthesis; Astrophysics; Ultra-thin silicon detectors; Inhomogenous Big Bang; MST; deadlayer; Pelletron; 8Li; cross-section; Kikuchi pattern; Physics and Astronomy;

   Sammanfattning : A new method has been proposed to study the low energy resonances of 8Li(alpha,n)11B at Ecm ≅ 0.5 MeV using dE-E Monolithic Silicon Telescopes (MSTs). Each telescope consists of five ultra-thin ∼1 µm (dE) silicon detector pads on a ∼500 µm (E) silicon detector. LÄS MER

3. 2. Investigating the stability of a laser-based plasma x-ray source

   Kandidat-uppsats, Lunds universitet/Kemisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Fredrik Parnefjord Gustafsson; Jens Uhlig; Wilfred Fullagar; Amal El Nahhas; [2016]
   Nyckelord :pulse energy; pointing; TES; transmission-edge-sensor; EXAFS; spectrum; spectroscopy; absorption; emission; time-resolved; Brunel mechanism; vacuum heating; water-jet; CCD; andor; LPXS; x-ray; plasma; laser; fluctuations; stability; pixel detector; beam profile sensor; resonant absorption; beam position; Physics and Astronomy;

   Sammanfattning : The use of laser based plasma x-ray sources (LPXS) has quickly expanded during the past decades due to rapid development of ultrafast laser systems. These sources are used in many research applications such as emission, absorption and particularly time-resolved spectroscopy. LÄS MER
