Summary of Working Group on Accelerator Physics and Machine Design and R&D.

Working Group on Accelerator Physics and Machine Design R&D at Nufact-2007 focuses on topics on accelerator physics and technical issues of hardware components associated with a Neutrino Factory or its subsystems. There were 32 presentations given at the working group. A special session was held to discuss collaboration opportunities with the Muon Collider Task Force (MCTF) at Fermilab in consideration of many overlaps in the machine R&D between a Neutrino Factory and a Muon Collider. Two more sessions were held jointly with Working Group 2 on muon collection schemes and other related subjects. [ABSTRACT FROM AUTHOR]
