  6. SciFi Target Tracker option cost • Fiber: 1/8.6 of the total fiber length for the LHCb SciFi. 2750 kCHF /8.6 = 320kCHF (12 stations, 15 x 7 ribbons) • Honeycomb panels: 50 kCHF • FE Electronics: The same number of boards, but no -40 C cooling and simple serial Ethernet interface :~1000 KCHF. • Special production equipment: 30 kCHF • Consumables, chemicals, and CR maintenance: 40 kCHF. Total ~1500 kCHF 11 February 2016 SciFi TT Option 6

  16. SciFi production status update • The KI personnel is trained at RWTH, Aachen, to operate the production and the QA equipment (October 2015). • Winding machine is being shipped to NRC KI (pickup date was January 29th ) and is expected to be delivered this week. The first winding wheel is ready; • The production zone at KI, the clean room, will be integrated by March 14th. • All necessary production and QA equipment will be operational by the LHCb SciFi Production Readiness Review in May 2016. • The fibers and other consumables delivery contracts are being negotiated (delivery profiles, batch sizes and rates). 11 February 2016 SciFi TT Option 16

  17. Fiber and ribbon QA status update • Fiber QA scanner is at the final stage of the integration (all the mechanics parts and motors are integrated, all the electronic boards and power supplies are produced and delivered, the light leak detector is ready, the laser micrometers and the control electronics are the last to be integrated). The software is ready. • Ribbon QA custom made optical stand is ready. The software to detect and to measure fiber's positions and diameters is ready. • The neural net based code to detect the fiber's shape defects and as well as the optical output variations (brightness, color) is being tested. • The Sr90 SciFi light yield and uniformity stand is being built. 11 February 2016 SciFi TT Option 17

  18. Plans towards CDR • Securing R&D funds. • Target tracker geometry optimization (together with the neutrino target detector). • Detailed tracker MC simulation together with the neutrino detector to evaluate its performance. • Production of the qualification module and electronics (Module 0, or technology demonstrator) and its mechanical study. • The Beam tests of the Module-0 • Engineering Design Review 11 February 2016 SciFi TT Option 18

  19. Conclusions: • Big way ahead, but the work done for the LHCb SciF tracker makes it a lot shorter. • We welcome motivated people to join it. Thank you! 11 February 2016 SciFi TT Option 19
