AGM-2011 On behalf of CO/FE F.Locci - December 15 th, 2011

 About 20 years that VMEBus was officially introduced as CO standard platform (PS/SL 1990 Controls renovation)  Over 1000 FECs deployed for operation including 550 PowerPC/LynxOS  From 2007, we faced with VME platform obsolescence in LHC Injectors chain  2009 (ACCOR): Major contract with Industry to use multi-core Intel/Linux (Today: 10%  LS1: 50%)  In view of LHC upgrade phases and next generation accelerators (CLIC), we think it’s time now to provide state-of-art on Front-End architecture and assess new solutions for the future  VME is slightly behind its industrial competitors that are ready with new technologies: Compactness, Performance and High-Availability 12/15/2011AGM What's next in the COFE room?

 Indeed, since 2006 Telecom market made significant investments to define Embedded RT hardware: MicroTCA  AdvancedTCA(ATCA)  MicroTCA (yTCA)  MicroTCA opportunity?  Inherits ATCA capabilities: Bandwith, Performance, Robustness, RAS  Open architecture (PICMG consortium)  Protocol agnostic (PCIe, GbEthernet, RapidIO,..)  Global and Intelligent remote management (IPMI)  Small form factor system  Cost-effective solution  MicroTCA for Physics (xTCA)  High-data transfer rates  Rear Transition Module (extended IPMI)  Backplane timing distribution and signal triggering  Physics community already opted for xTCA architecture (SLAC, DESY,..) 12/15/2011AGM What's next in the COFE room?

 Several years of R&D resulted in the first CLIC Design Conception (CDR1 for Controls)  In particular, CO/FE has to provide Generic read-out system (ACM) for all two-beam modules (TDR 2016)  ACM Design is rather challenging:  Integration and compactness: modules  Radiation hardness: ~1kGy/year (  no CPU, no OS)  Low power consumption: <0.5W/IO ch. (100W/ACM)  Synch. LAN data transfer between ACM and CLIC control system (immune to EMC)  Remote Configuration and Diagnostic facilities  … 12/15/2011AGM What's next in the COFE room?

 BE/CO has been mandated to steer the evaluation and prototyping activities CLIC Control system  2012: Focus on Beam Instrumentation for CTF3 (LAPP)  CLIC is extremely ambitious, but it is just starting … one can bet on Technological advances and Collaboration  BE/CO has direct interest to evaluate new platform for future use (LHC included) and to invest on potential improvement of the CO multi-tier approach 12/15/2011AGM What's next in the COFE room?
