  1. SPARC activitiesat Roma2 • INFN-Roma2 • L. Catani, E.Chiadroni, A.Cianchi, E. Gabrielli, M.Raparelli, S.Tazzari, M. Sabene(DAQ), G. Salina (DAQ), A. Salamon (DAQ) • INFN-LNF (Emittance-meter) • M.Castellano, A.Clozza, M.Ferrario, V.Fusco, D.Filippetto, V.Lollo, G.Di Pirro, C.Ronsivalle (ENEA)

  2. Presentations • Emittance-Meter (this talk) • Console System Design & E-Logbook (E.Gabrielli) • Bunch Length Measurement (E.Chiadroni) • data collection system for DAQ (this talk)

  3. Emittance-meter Layout (1)

  4. Emittance-meter Layout (2)

  5. Emittance-meter Layout (3)

  6. bellows delivered • new design for bellows support • table design completed • ready to order • design requirements (e.g. minimum distance from cathode are fulfilled) MechanicalComponents

  7. longitudinal movement designed (100 µm accuracy) • differential encoder + potentiometer for position read-out • stepper motors defined • ready to order • X-Y steerings under study • similar design as for linac steerings Long mover and steerings

  8. goniometer stage + rotating stage for h-v pepper-pots tilt control • originally selected from Micos catalog have now been custom designed (suited for our purposes and cheaper) • 0.6 mrad accuracy/resolution Results obtained so far cannot confirm the reliability of measurements even when the alignment of the pepper-pot is as low as 1–2 mrad, i.e. we cannot guarantee that emittance measurement results will not be effected by a 1–2mrad tilted pepper-pot Pepper-pot

  9. accuracy of the pepper-pot vertical movement will be better than 2µm. • this accuracy is needed for the single-slit (or multi-shot) emit.meas • diff. encoder + potentiometer will provide position read-out • second pepper-pot ready to order • firm will assure machining precision of 5 µm • all slits will be measured and certified • YAG screens delivered and ready to be tested at BTF Pepper-pot (2)

  10. Camera System

  11. Camera System (2) • preliminary results: Macro Objective resolution: ~25 µm @ 13 cm • improvements are possible • remote focus control under study

  12. DAQ

  13. Data Hub for DAQbased on PCI-PCI link

  14. Reflective memory board with fiber optic interface • Reflective memory board • 64 bit x 66 MHz Master/Slave PCI interface with DMA engine • 1 MByte Synchronous Static Dual Port RAM • Fiber optic full-duplex high-speed link (850 nm VCSEL laser) • To be added: block diagram

  15.

  16. Printed Circuit Board • 12 layers • 5 routing layers • 7 ground and power planes • Controlled impedance for external layers(for high-speed link)

  17. FPGA Firmware • 64 bit x 66 MHz DMA engine:instruction loaded by the driver with PCI target operationand then data transfer is performed by the board with PCI master RD and WR operations (the CPU is freed) • DPRAM: can receive data from the link and send data to the PCI interface at the same time • Fast alert via PCI interrupt when DPRAM given memory locations are written • TO BE ADDED: Dataflow and bottleneck description • Customizations upon request

  18. Costs • Altera ACEX 1K 100 FPGA: 82,00 Euro (bought) • Cypress CY7C0853V-100BBC SDPRAM: 130 Euro (bought) • Texas TLK2501CP SerDes: 16,00 Euro (www.ebv.com) • Agilent HFBR5720-AL Transceiver: 50,00 Euro (bought) • AMP Surface Mount socket 1367073-1 (50 Euro ? To be confirmed) • Other components (100 Euro ? To be confirmed) • Board manufacturing (ELCO, agreement):700,00 Euro (NRE)+ 460,00 Euro/PCB (4 pcs, 10 working days)+ 110,00 Euro/PCB (20 pcs, 25 working days) • Board population (100-150Euro/board ? To be confirmed) • OVERAL COST: ~700 EURO/board* *(IVA not included)

  19. Time schedule • Components selection: OK • Schematic: OK • PCB: placement OK, routing FPGA<=>PCI OK, routing FPGA<=>Serdes and FPGA<=>DPRAM to do • Firmware: most of the work has been done (M. Sabene) • Board manufacturing: 10 working days • Board population: 10 working days • Driver: to do (Emiliano has already experience !)

  20. Communication Protocol • A “C” version of the LabVIEW-based communication protocol for the Control System in under study to be used • .. for DAQ as alternative to the PCI board under development • .. to integrate components that cannot be controlled with LabVIEW

  21. Conclusions • development of the Emittance-meter system is going on according to schedule • critical components have been either ordered or ready to order • studies for the Console System have been completed and the project specs have been given to the SPARC Control Group • next step in Control System schedule is completion of software for E-meter components (motors, read-out, ..) and DAQ • preparation of bunch length experiment at TTF provided very good experience for the design of the SPARC measurement system
