A simplified Recycler lattice was created to fine tune injection straight, ring tune, and phase trombone. In this paper, we will present detailed modifications for further optimization of Recycler lattice which require the investigation of tune footprint and dynamic aperture based on higher order momentum components of the magnetic fields, together with the space charge effects.

One of the initial motivations for replacing the aging Fermilab Proton Source was to support the 120 GeV Neutrino program at the 2 MW level while supporting a broad 8 GeV Physics program. Over the years the design parameters of the new Proton Source have evolved from the 2005 Proton Driver configuration of a 2MW 8 GeV pulsed H- linac injecting directly into the Main Injector or Recycler ; to a 2MW 2 GeV CW linac supporting a 2 GeV Experimental Program while injecting into a new 2-8 GeV Rapid Cycling Synchrotron which would then supply protons to the Main Injector. The current design parameters of the project include a 3 GeV CW linac accelerating up to 1 mA (average) H- and a 3 GeV Experimental Area with the connection to the Main Injector Complex as an upgrade. Whether the upgrade path includes a new 6(or 8)GeV CW or pulsed linac, or 3 to 8 GeV RCS and the ultimate linac current remains to be determined. The basic issues of injection insertion design, foil and laser stripping options, foil survivability and loss issues will be discussed in context of the present options. Both analytical estimates and simulation results will be discussed.

We review the presentations and discussions of the Accelerator System Design, Injection and Extraction working group at the 46th ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams.
