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

Proton Source Workshop


Aperture scan on current operation

  • Using 3bump

  • Loss monitor

    • H: F-magnet

    • V: D-magnet

Booster acceptance apertures and alignment kiyomi seiya

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.
