  1. 11. Interaction between High-velocity Penetrators and Moving Armour Components

    Författare :Ewa Lidén; Bengt Lundberg; Hevré Couque; Uppsala universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : This work was aimed at understanding mechanisms of importance for the design of weight-efficient armour against long-rod projectiles (LRP) and shaped charge (SC) warheads. The focus was on how to achieve effective mechanical disturbances on the threat before it hits the target. LÄS MER

  3. 12. Electron-transfer processes in fast ion-atom collisions

    Författare :Kristian Støchkel; Henning Schmidt; Henrik Cederquist; Andreas Wolf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron transfer processes fast ion atom collisions hydrogen helium; Atomic and molecular physics; Atom- och molekylfysik;

    Sammanfattning : The subject of this thesis is experimental studies of electron-transfer processes in ion-atom collisions at velocities significantly higher than typical orbital velocities of electrons in bound states of atoms or molecules. The experimental technique applied combines the high beam intensity of heavy-ion storage rings with a supersonic gas-jet target equipped with a recoil-ion-momentum spectrometer. LÄS MER

  4. 13. Interaction of Cylindrical Penetrators with Ceramic and Electromagnetic Armour

    Författare :Lars Westerling; Kristofer Gamstedt; Bengt Lundberg; Nils G. Ohlson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : Armoured vehicles have traditionally used steel armour as protection against penetrators such as projectiles and shaped charge jets. The latter produce a thin stretching metal jet, usually of copper, with a tip velocity of about 7-8 km/s. LÄS MER

  5. 14. Heavy particle interference and diffraction in fast electron transfer collisions

    Författare :Magnus Gudmundsson; Henrik Cederquist; Henning Schmidt; Erik Horsdal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; fysik; Physics;

    Sammanfattning : This thesis presents experimental results from the synchrotron cooler and storage ring CRYRING on charge transfer processes in fast electron transfer collisions using high-resolution cold target recoil-ion momentum spectroscopy. The main focus of these studies was to investigate a key concept of quantum mechanics: the wave-particle duality. LÄS MER

  7. 15. Experimental Studies of Neutron Emission Induced by Heavy-Ion Scattering

    Författare :Pawel Nadel-Turonski; Leif Nilsson; Adriaan van den Berg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; inelastic scattering; heavy ions; position sensitive silicon detectors; storage ring; cluster-jet target; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : A beam of 250A MeV 17O ions was scattered from argon and xenon targets. The large excess of fast neutrons compared with statistical model calculations that was observed earlier for xenon, was confirmed and found for argon as well. LÄS MER
