  27. Conclusions 1 • Standards for hardware have passed 2 major milestones • Committees will disband when SOWs complete • Software committee continues developing guidelines for architecture and protocols • Member labs remain involved in PICMG through Coordinating Committee for oversight, servicing tweaks • Start new initiatives, SOWs, form committees as needed New xTCA Developments at SLAC - R. Larsen

  28. Conclusions 2 • SLAC new initiatives open future opportunities • Main Linac RF upgrades for LCLSII, I. • BPM upgrades for LCLSII Injector, Main Linac • Interlock systems wholly contained in MTCA.4 combined RF-Controls package • Long range: Complete replacement CAMAC controls in 2-mile accelerator, $20M program • Timeline: • RF and interlock demos complete in Q1-2 FY12 • BPM AIP completes Q2 FY13 New xTCA Developments at SLAC - R.
