  • Target roughness study and rotating target - Bob elog-3005


  • Rotating target idea for PREX,
    • non-uniformity of the lead target is the biggest problem PREX have
    • going to rotating target would make this issue worse
    • Goal for going to rotating target is luminosity but the main issue is asymmetry widths
    • Organize a meeting to update Thia about all sides of the story about PREX target.
  • Also discuss engineering manpower issues and review for PREX with Thia
  • Get correct TOSCA model for PREX septum from Paul Brindza for Juliette
  • We need to decide Qweak scattering chamber will be used for PREX or not
    • Issue with Qweak chamber is that interfacing with the sieve box
    • Advantage of the Qweak chamber is that use of the 2D qweak target ladder
    • Reason we moved away from old target chamber was the interfacing with the sieve box
  • Hall may be open till end of November and beam in hall after thanksgiving - Kent, Bob
    • If the hall is going to be closed sooner we need to know it
  • Solid target rates
    • estimate solid target rates (11 GeV beam rates on lumi) so that we can decide about the target thickness


TO DO Lists

  • It would be nice to have real-time viewer for optics studies in commissioning (discussed in 01/16/2014 meeting)
