2. February 17-18, 2010 R&D ERL Gary McIntyre ERL Status & Schedule Although important to C-AD, ERL must compete for resources with machine operations – –Sharing resources limits the work that can be performed…  During shutdown periods  Operations maintenance days  Anytime ERL work is in conflict with operations efforts –Best efforts are being made by all ERL-involved groups but schedule slip can and does occur. 2
