   Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

3. 2. Multi-ion radiotherapy treatment planning

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Gustav Lidberg; [2023]
   Nyckelord :multi-ion radiotherapy; heavy-ion radiotherapy; carbon-ion radiotherapy; treatment planning; LET optimization;

   Sammanfattning : Multi-ion radiotherapy has been suggested as a new way to treat cancer, combining the radiological advantages of lighter and heavier ions in a single treatment to improve plan robustness and increase LETd in the target. To succeed, multi-ion radiotherapy requires a treatment planning system capable of computing dose for and optimising multi-ion treatment plans. LÄS MER

4. 3. Neutron backgrounds in neutrino-nucleus scattering at the European Spallation Source

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :José Guilherme Rodrigues de Albuquerque Vale; [2023]
   Nyckelord :Neutrino-nucleus scattering; background; PHITS; weight window; ESS; Physics and Astronomy;

   Sammanfattning : Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). LÄS MER

5. 4. Non-Diffractive Nuclear Excitations In Angantyr

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Carl Rosenkvist; [2023]
   Nyckelord :Heavy-ion; non-diffractive; nuclear excitation; secondary interactions; Physics and Astronomy;

   Sammanfattning : To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. LÄS MER

7. 5. On the Energy Dependence of Parameters in PYTHIA8 Heavy-ion Collision Simulations

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Felipe Abedrapo; [2022]
   Nyckelord :Heavy-ion Collisions; PYTHIA; Angantyr; Physics and Astronomy;

   Sammanfattning : Particle collisions are an essential component to the research methodology of particle physics. These investigations are not only conducted in experimental laboratories but also through programs such as PYTHIA that simulate a collision or ``event" and then compare its results to known experimental data.
