16. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER
17. 3D Coating of Interface Materials for High-Performance RF Passive Devices
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The demand for high-performance Radio Frequency (RF) passive devices has been steadily increasing due to the growing complexity and sophistication of wireless communication systems. The Quality factor (Q-factor) is a key parameter for describing the signal losses and the energy efficiency of resonators. LÄS MER
18. Digital Microwave Control of Superconducting Qubits
Master-uppsats, KTH/Tillämpad fysikSammanfattning : We manipulate two superconducting qubits using digital microwave electronics. Starting fromtheir characterization, we develop a real-time reset scheme and implement the iSwap gate. Thequbits’ parameters are obtained using standard single-qubit characterization techniques, such asRabi and Ramsey oscillations and frequency sweep of the resonators. LÄS MER
19. Principkonstruktion för kvalitetsbedömning av medicinska slangsvetsfogar
Kandidat-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : Medicinska plastslangar har en väsentlig roll inom sjukvården, vilket även ställer krav på de maskiner som försluter dessa slangar. Den typ av förslutningsteknik som beskrivs i rapporten är radiofrekvenssvetsning, som sammanfogar en utvald del av den medicinska slangen till en svetsfog. LÄS MER
20. Tuning of the ESS Drift Tube Linac using Machine Learning
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS ABSammanfattning : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. LÄS MER
