Recommendations From the Proton Plan Directors
Review

• Strengthen accelerator physics efforts to guide
  the implementation and commissioning of the
  correction systems. In particular with respect to
  tune and resonance control, utilize the
  experiences of other accelerators, both in
  performance and calculations, to aid in this
  effort. Develop a commissioning plan for the new
  correction elements.
• At the next review, present the status of
  accelerator physics calculations for the
  injection process and for tune and resonance
  control.
• Note Id like focus on the Booser in this
  meeting. Well get to the Linac before long

2
Status of Booster Modeling

• Lots of work has been done.
• Quite a few things have been learned.
• Weve never been good at presenting this in a
  concise way.
• Not a lot of communication between different
  modeling efforts.

3
Booster Modeling Fronts

• Injection and early cycle
• Space charge, alignment, capture, painting, etc
• ORBIT (Weiren Chou, Phil Yoon, ??)
• Synergia (Panagiotis, Linda, Dan McCarron)
• ESME (Jim Machlaclan, long.)
• STRUCT (Yang Xi, Sasha Droxhdin)
• Transition
• ESME
• STRUCT
• Resonances and instabilities
• Calculation and measurement (many people)
• Collimation and Loss patterns
• MAD, STRUCT, MARS (Drozhdin, Mokhov)

The March of Progress

• When serious attempts to model the Booster began.
• It was discovered that the extraction doglegs
  (and ORBUMP a bit) were badly distorting the beam
  optics
• The beam position mismatch at ORBUMP made
  fundamental understanding at injection very
  problematic
• Now
• Lattice distortions reduced to small perturbation
• Long 3 rearrangement
• Long 13 removal
• New ORBUMP system
• New ORBUMP system gives us much greater control
  of injection, including the ability to exactly
  match the orbiting beam.

5
Goal of This Meeting

• Find out what everyones done and what theyre
  doing.
• Begin to work toward a standard stump speech
  about the general state of Booster Modeling.
