Barcelona 1 Development of new technologies for accelerators and detectors for the Future Colliders in Particle Physics URL

Barcelona 2 Working Plan for future Colliders Off-detector and transfer electronics –Module controller (UB) Design of this module is to be done closely with interconnection and data transfer. –Interconnection and data transfer. Data transfer rate from ASIC to module controller and finally to readout and off-detector electronics can be as high as 20GB/s if occupancy is high and data sparsifying is not possible [ILC-RDR2007]. Physical connections: optical fiber or LVDS serialization. –Objective: reduce noise, cabling and connectors. –Study of EMC and signal integrity required. Task is closely related to System Integration and Engineering. ILC Santiago 2008

Barcelona 3 Working Plan for future Colliders Off-detector and transfer electronics –DAQ: Design and test of a stand-alone portable setup. –Same setup for Lab and testbeam. FPGA-based dedicated boards connected to PC for analysis. –VHDL FPGA firmware. –Acquisition and analysis software on PC. –Testbeam preparation: Adaptation boards for signal format/level conversion. Overcome limitations of available facilities. Real-time data analysis to allow in-site test decisions to better profit from available beam characteristics. ILC Santiago 2008

Working Plan for future Colliders DHP for Belle II –SEU protection for memory cells (Hamming correction or others…) FPGAs -> URL ASIC -> MPI (Andreas) –Interface DHP-DHH and DHH-back-end electronics To be done in close contact with KEK (URL) Gigabit TX (physical, coding, FEC…) –FPGAs -> URL –ASIC -> U.Bonn Barcelona 4 DHP Meeting UB 2008

Working Plan for future Colliders Project Status: DEPFET officially approved for Belle II !!! –But geometry of beam pipe and cooling system not decided yet Will affect number and size of modules …which in turn will affect data rate –Must not make strong assumptions, find flexible solution that can be adapted to either outcome E.g. serializing ratio, channel coding –Fortunately, we are in the FPGA part Barcelona 5 KEK Meeting 2008

Working Plan for future Colliders Better understanding of mechanical issues, cooling. But nothing fixed yet, number of pixels and readout time not decided  data rate unknown. Must be very flexible, foresee different options Barcelona 6 Ringberg 2009

Current System level integration on Belle –Physics and overall Participation on meetings and following discussions –Radiation dose study Will affect FPGA family selection, code selection, etc… CERN (July’2009 ?) –Willing to participate. Great opportunity to connect to DEPFET people and take a global system picture. But… very few manpower on our group Barcelona 7

Current Gigabit TX –First Tests on LVDS TX Very FPGA dependent (Stratix w/o DPA, Stratix II ok, Stratix II+ GX version may be required). Parameter tuning is critic: lots of things to be understood. 1 Gbps on Stratix II GX done Barcelona 8

Current Gigabit TX –Development board acquisition Transceiver Signal Integrity Development Kit, Stratix II GX Edition –Preparing lab setup for BER test (with perturbations) –Protocols Serial RapidIO (up to 3.125Gbps) Gigabit Ethernet Barcelona 9

Current SEU Protection & FEC codes –SEU Protection for memory cells Hamming correction implementation cost on FPGAs FPGA vendor and family comparison considering radiation dose, system performance, etc… (Altera, Actel, Xilinx …) –Coding and FEC cost and alternatives Barcelona 10

Current System integration on FPGAs –NIOS II evaluation and setup Useful on lab setups and prototyping –Firmware development Defining collaboration with U.Giessen Barcelona 11
