Why ACAS?
Motivation• Grow the field of
accelerator physics• Sustain successful
accelerator based user facilities
• Develop student programs• Publish research findings• Contribute to Big Science
international collaborations
Challenges• Physics departments say it
is engineering• Engineering departments
say it is physics• “Only” user support not
science• No dedicated university
courses• Broad field to cover
