  2. 11. Development of the read-out link and control board for the ATLAS Tile Calorimeter Upgrade

    Author : Eduardo Valdés Santurio; Samuel Bryant Silverstein; Costas Foudas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HL-LHC; ATLAS; Tile Calorimeter; TileCal; Demonstrator; Daughterboard; Read-out; Digital electronics; Data acquisition; Radiation tolerant; GBTx; TID; NIEL; SEU; SEL; FPGA; Kintex 7; Ultrascale; Ultrascale ; Optic Links; fysik; Physics;

    Abstract : The Phase-II upgrade plan for the ATLAS Hadronic Tile Calorimeter facing the High-Luminosity LHC (HL-LHC) era includes approximately 1000 radiation tolerant read-out link and control boards (Daughterboards) that will provide full-granularity digital data to a fully-digital trigger system off-detector through multi-Gbps optic fibres. Different Daughterboard (DB) revisions have been developed, each successively aiming to meet the demanding HL-LHC requirements. READ MORE

  4. 12. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

    Author : Pawel Klimek; Christophe Clément; Barbro Åsman; Freya Blekman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS experiment; particle physics; high energy physics; supersymmetry; SUSY; beyond standard model; chargino; neutralino; slepton; vector boson fusion; VBF; Tile calorimeter; TileCal; pile-up; quality factor; Large Hadron Collider; LHC; CERN; fysik; Physics;

    Abstract : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. READ MORE

  5. 13. Testing large samples of PCM in water calorimeter and PCM used in room applications by night-air cooling

    Author : Rickard Bellander; Ove Söderström; Gudni Jóhannesson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change material; PCM; water calorimeter; air heat exchanger; durability; thermal properties; heat capacity; Building engineering; Byggnadsteknik;

    Abstract : The latent-heat-storage capacity in Phase-Change Materials can be used for storing or releasing energy within a small temperature interval. Upon the phase transition taking place in a narrow temperature span, the material takes up or releases more energy compared to sensible heat storage. READ MORE

  6. 14. Design of the HIBEAM/NNBAR Calorimeter and Upgrades to the ATLAS Tile Calorimeter Readout Electronics

    Author : Katherine Dunne; Samuel B. Silverstein; Klas Hultqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : The Standard Model has been greatly successful in predicting the laws that govern our universe. Yet there are still seemingly missing pieces to the model. READ MORE

  7. 15. Counting Calories : Studies of Energy Loss in a Segmented Calorimeter

    Author : Sara Bergenius Gavler; Per Carlson; Oscar Adriani; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : The Gamma-ray Large Area Space Telescope (GLAST) is a space mission with anticipated launch in 2007. The aim is to study the gamma-ray sky in the energy range 10 keV – 300 GeV. The GLAST electromagnetic calorimeter is 8.6X0 deep and has a total of 1536 CsI(Tl) crystals each measuring 32. READ MORE
