1. 21. Optimising the present and designing the future: a novel SPS injection system

   University essay from Uppsala universitet/FREIA

   Author : Elias Waagaard; [2022]
   Keywords : Numerical optimisation; injection; Super Proton Synchrotron; neural networks;

   Abstract : The Super Proton Synchrotron (SPS) injection system plays a fundamental role to preserve the quality of injected high-brightness beams for the Large Hadron Collider (LHC) physics program and to maintain the maximum storable intensity. The present system is the result of years of upgrades and patches of a system not conceived for such intensities and beam qualities. READ MORE

3. 22. Simulation of a prototype of the LDMX hadronic calorimeter and analysis of test beam data

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

   Author : Péter György; [2022]
   Keywords : LDMX; HCal; TS; prototype; Physics and Astronomy;

   Abstract : The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of dark matter in the mass range of 1 MeV - 1 GeV. It does so by looking for missing momentum and energy in collisions of an electron beam and a tungsten target, which could potentially indicate the existence of dark matter. READ MORE

4. 23. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
   Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

   Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

5. 24. Designing a New SPS Injection System With Numerical Optimisation

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Elias Waagaard; [2022]
   Keywords : Hierarchical optimisation; injection system; kicker magnet; septa; genetic algorithms;

   Abstract : The Super Proton Synchrotron (SPS) injection system plays a fundamental role to preserve the quality of injected high-brightness beams for the LHC physics program and to maintain the maximum storable intensity. The present set-up is the result of years of upgrades and patches of a system that was not conceived for such intensities and beam qualities. READ MORE

6. 25. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

   University essay from

   Author : Louise Strandberg; [2021-04-06]
   Keywords : Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

   Abstract : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. READ MORE
