  3. 12. Criticality of fast failures in the High Luminosity Large Hadron Collider

    Författare :Björn Lindström; Roger Ruber; Daniel Wollmann; Maja Olvegård; Annika Nordt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine protection; failures; beam losses; accelerator physics;

    Sammanfattning : Each of the two Large Hadron Collider (LHC) beams contain 362 MJ of energy. This will be further increased to 678 MJ in the upcoming upgrade to the High Luminosity LHC (HL-LHC). In the event of an uncontrolled beam loss, a significant hazard occurs, that can damage the machine components. LÄS MER

  4. 13. Crowded Field Photometry and Luminosity Function Analysis as Probes of Galactic Evolution

    Författare :Ralph Snel; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; observational; Methods: data analysis; statistical - Techniques: photometric - Stars: luminosity function; imaging; evolution - Galaxies: stellar content; mass function; space research; cosmic chemistry; Astronomi; rymdvetenskap; kosmisk kemi; Fysicumarkivet A:1998:Snel;

    Sammanfattning : Crowded field photometry is a powerful method to investigate stellar evolutionary processes in astrophysically interesting regions such as nearby external galaxies and globular cluster cores. While detectors are approaching the physical limits for photon detection, data analysis methods for crowded stellar fields are not yet equally sophisticated. LÄS MER

  7. 15. Luminosity Measurements and Two-Photon Physics with the DELPHI VSAT at LEP

    Författare :Per M Jonsson; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; kvantfältteori; Elementarpartikelfysik; quantum field theory; Fysicumarkivet A:1998:Jonsson;

    Sammanfattning : This thesis describes analysis of data from the DELPHI Very Small Angle Tagger (VSAT) calorimeter at LEP1. The VSAT consists of four Silicon-Tungsten calorimeter modules symmetrically positioned 7.7 meters away from the interaction point. LÄS MER
