Summary • Scope of DCO components for XPP, CXI, and XCS instruments has not changed significantly since CD-02 • The design of key diagnostics devices and optical components is mature and based on proven developments – at synchrotron sources worldwide – by XTOD and LCLS e-beam groups • No major risks associated with the design or procurement of the DCO components – Bought components (slits) are “off the shelf” items – Assembly components (CCD cameras, zoom lens, actuators, connectors) are commercially made with known performance – In-house electronics design are based on proven technology and implementations – ARRA bureaucratic strings could delay awarding contracts • DCO is on track to support early science!
