TUIB —  Invited Talk in Tuesday-B   (02-Oct-12   10:35—12:05)
Bigger, Brighter and more Powerful
  • H. Schmickler
    CERN, Geneva, Switzerland
  The community of high energy physics has several proposals for more powerful accelerator projects. This presentation reviews all current projects with center of mass energies above 10 GeV in the field of hadron accelerators, lepton colliders and lepton-hadron colliders. Special emphasis is given on the new needs for beam instrumentation.  
Femtosecond Resolution Bunch Profile Diagnostics
  • B. Schmidt
    DESY, Hamburg, Germany
  The generation of ultrashort x-ray pulses in the femtosecond (fs) regime in FELs requires electron bunches with lengths significantly below 1 ps with a strong tendency to aim for the 1 fs scale. This greatly challenges the present beam diagnostic methods. In this paper, we will present an overview of the existing and proposed techniques of bunch profile diagnostics including transverse deflecting cavities, electro optic methods, frequency domain techniques as well as more complex approaches like "optical replica synthesizers" (ORS).
