ALICE (accelerator) - Principle
... A DC photoelectron gun generates short low emittance electron bunches with the length of several ps and accelerates them to a modest 350keV ... The electron beam is then injected into the superconductive linac (booster), accelerated to the energy of 8.35MeV and transported to the main linac that increases the beam energy to 35MeV ... The beam reaches the chicane after being turned by 180° in the first triple bend achromat ARC1 ...
Mass-to-charge Ratio - Charge-to-mass Ratio - The Electron
... The elementary charge-to-electron mass quotient, is a quantity in experimental physics ... It bears significance because the electron mass me is difficult to measure directly, and is instead derived from measurements of the elementary charge ... measurement convinced him that cathode rays were particles, which were later identified as electrons, and he is generally credited with their discovery ...
Swiss Light Source
... Main component of the SLS is the 2.4 GeV electron storage ring of 288 m circumference The ring is formed by 36 dipole magnets of 1.4 tesla magnetic field ... A total of 177 quadrupole magnets (magnetic lenses) focuses the beam to provide an beam emittance of 5.5 nm rad. 73 horizontal and vertical beam steerers are used to continuously correct the position of the electron beam ...
Mott Scattering
... scattering, is the separation of the two spin states of an electron beam by scattering the beam off the Coulomb field of heavy atoms ... used to measure the spin polarization of an electron beam ... Mott Scattering is similar to Rutherford Scattering but electrons are used instead of Alpha particles as they have much lower mass (by about 4 orders ...
Gold Compounds - Applications - Medicine
... In ultrathin sections of tissues viewed by electron microscopy, the immunogold labels appear as extremely dense round spots at the position of the antigen ... as plastics and glass to be viewed in a scanning electron microscope ... to earth, and its very high density provides stopping power for electrons in the electron beam, helping to limit the depth to which the electron beam penetrates the specimen ...

Famous quotes containing the word beam:

    What do we plant when we plant the tree?
    We plant the ship that will cross the sea,
    We plant the mast to carry the sails,
    We plant the planks to withstand the gales—
    The keel, the keelson, and beam and knee—
    We plant the ship when we plant the tree.
    Henry Abbey (1842–1911)
