    Author : Shelley Brown; Göran Lindbergh; Robert Spotnitz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithium-ion battery; LixNi0.8Co0.15Al0.05O2; LixMn2O4; LiyC6; ageing; three-electrode measurements; impedance modelling; surface film characterisation; hybrid electric vehicle; low-earth-orbit satellite; litiumjonbatteri; åldring; treelektroduppställning; impedansmodell; ytfilmskarakterisering; hybridfordon; satelliter; Electrochemistry; Elektrokemi;

    Abstract : Lithium-ion batteries are a possible choice for the energy storage system onboard hybrid electric vehicles and low-earth-orbit satellites, but lifetime performance remains an issue. The challenge is to diagnose the effects of ageing and then investigate the dependence of the magnitude of the deterioration on different accelerating factors (e.g. READ MORE

  5. 3. The Anticoincidence Shield of the PAMELA Satellite Experiment

    Author : Silvio Orsi; KTH; []
    Keywords : astrophysics; particle physics; antimatter; organic scintillators;

    Abstract : The PAMELA space experiment is scheduled for launch towards the end of 2004 on-board a Russian Resurs DK1 satellite, orbiting Earth at an altitude of 300– 600 km. The main scientific goal is a study of the antimatter component of the cosmic radiation. The semipolar orbit (70. READ MORE

  6. 4. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

    Author : Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

    Abstract : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). READ MORE
