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 CERN, 12 April 2011CLIC/ACAS Update - Mark Boland9
