survey and data analysis
Survey and data analysis
  • December, 1993(S. Shukla)
    • F-magnet, D-magnet
  • April, 2005 (O. Oshinowo, P. Kasper)
    • F-magnet, D-magnet
    • BPM
  • August , 2009(O. Ohinowo)
    • F-magnet, D-magnet
    • Corrector magnet
    • RF cavity

Proton Source Workshop

magnet move
Magnet move
  • December, 1993(S. Shukla)
    • Moved magnets and improved aperture
  • April, 2005 (J. Lackey)
    • Moved F & D in horizontal & vertical

Proton Source Workshop

lattice calculation
Lattice calculation
  • Shukla’s program - Java application (A. Wallace)
    • Last update was in 2006
  • MAD v8 – Console application (W. Marsh)
    • 1994 (C. Johnstone)
      • Calculated with alignment error on F & D magnet and compared with ideal lattice
    • 2001-2003 (A. Drozhdin)
      • Calculated Dog leg magnet at injection and compared with measurement.
    • 2010 (J. Lackey)
      • Put all components including new correctors

Proton Source Workshop

aperture scan
Aperture scan
  • November, 1994 (D. McGinnis, S.Shukla)
    • B75
    • Moved magnets
  • December, 2003 (B. Pellico)
    • Before septa was moved to MI-8 from L13.
  • December, 2004 (B. Pellico)
    • Measured lager aperture after septa was moved.

aperture scan with b75
Aperture scan with B75
  • Using 3bump
  • DCCT
  • Need to be modified for the new correctors
    • CAMAC card (465  473)
    • Bump ratios
    • Current limit

Next…
  • Aperture scan
    • 1 bump, 3 bump or 5 bump
    • Modified B75
  • Survey data analysis
    • Data from August, 2009
  • Lattice calculation
    • Make sure that all elements are in MAD file.
    • Put in alignment error.
    • Compare with Shukla’s.
