  28. VISA I ® VISA II • VISA 1998 - 2001 • Funding stopped in Mid 2001 • VISA II Proposal 2002 (Collaboration UCLA-SLAC-Brookhaven-...) • New Funding from ONR arrived! Heinz-Dieter Nuhn, SLAC / SSRL email: nuhn@slac.stanford.edu

  30. Physics Goals of VISA II Install bunch compressor in the ATF Mitigate severe non-linearity of bend beamline Diagnose beam completely at end of transport Study FEL with compressed beams Use FEL as diagnostic of compressor… Study FEL with chirped, but uncompressed beams Impact LCLS schemes using chirping Study gain v. chirp Direct diagnosis of FEL longitudinal pulse characteristics Heinz-Dieter Nuhn, SLAC / SSRL email: nuhn@slac.stanford.edu
