5. John N. Galayda LCLS Facility Advisory Committeegalayda@slac.stanford.edu 29 October 2007 FY2008 contingency risks and handling Limited Budget Authority in FY2008 If contingency use in 2008 is too high: Delay start of installation of undulator to “just in time” with respect to schedule for x-ray flux measurement in July 2009 - ~ $3M BA released in FY2008 The risk handling plan reduces the available commissioning time CD-4 achievable on schedule (7/2010) Reduced performance in early operations
