19. Detector Roadmap • Detector time line should be synchronized with accelerator time line • because detector construction time would be similar to accelerator construction time • 2010: ‘light’ two detector EDRs • To be ready together with the accelerator EDR • Not for construction • Cost accuracy consistent with that for accelerator • 2008: Select two groups to write EDRs based on LOIs. • October 4, 2007: • ILCSC announces call for LOIs, due 1 October 2008.
