  1. 1. Discovery potential and characterisation of the parity properties of a new spin-0 boson at the LHC and HL-LHC.

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :AN Di; [2020]
    Nyckelord :hierachy problem; beyond Standard Model physics; LHC phenomenology; HL-LHC;

    Sammanfattning : We investigated the discovery potential and possibilities of characterizing the parity of a new spin-0 boson at LHC and HL-LHC only using di-photon channel. Our results show that it is possible to have a 5σ discovery and characterize the parity at 2σ level for given combinations of couplings and masses. .. LÄS MER

  2. 2. A Linear Framework for Orbit Correction in the High-Luminosity Large Hadron Collider

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Andersson; [2019]
    Nyckelord :CERN; HL-LHC; LHC; accelerator physics; orbit correction; error correction; closed orbit; Twiss; beam dynamics; dynamical systems; Python; Mathematics and Statistics;

    Sammanfattning : In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. LÄS MER

  3. 3. Phased Array Ultrasonic Testing of Austenitic Stainless Steel Welds of the 11 T HL-LHC Dipole Magnets

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Marcus Lorentzon; [2018]
    Nyckelord :Phased Array Ultrasonic Testing; PAUT; Non-Destructive Testing; Austenitic Stainless Steel; Welds; CERN;

    Sammanfattning : A routine non-destructive test method based on Phased Array Ultrasonic Testing (PAUT) has been developed and applied for the inspection of the first 11 T dipole prototype magnet half shell welds, and the test results are compared with the radiography and visual inspection results of the same welds. A manual scanner and alignment system have been developed and built to facilitate the inspection of the 5. LÄS MER

  4. 4. A study of underground rescue chambers as alternative to several egress paths

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Johannes Corbee; [2016]
    Nyckelord :Rescue chamber; refuge alternatives; refuge chamber; safe haven; emergency cabin; underground environment; evacuation; Technology and Engineering;

    Sammanfattning : This study has investigated the usage of rescue chambers as an alternative to additional egress paths. The new underground facilities at CERN that are planned as a part of the HL-LHC project have two proposed designs with rescue chambers or additional egress paths. LÄS MER

  5. 5. Comparative study of risk analysis methods from a fire safety perspective - Case study of new underground facilities at CERN

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Frida Olin; Erik Isaksson; [2016]
    Nyckelord :Risk analysis methods; design fires; event tree analysis; preliminary hazard analysis; What-if; ROGA; Gretener method; NFPA 101; comparative analysis; CERN; technical risk analysis methods; case study; LHC; HL-LHC; complex methods; simplified methods; Technology and Engineering;

    Sammanfattning : This report has investigated which type of risk analysis methods that can be used in an early design phase in a unique facility from a time and quality perspective. Two planned underground facilities for the HL-LHC at CERN have been used as a case study. LÄS MER
