Silicon Vertex Detector Schedule 23 July 2012 Christian Irmler (HEPHY Vienna) 12 th Open Meeting of the Belle II Collaboration

SVD construction schedule 2Christian Irmler (HEPHY Vienna)23 July 2012 MS Project Considers dependencies between tasks Not complete yet Need information from collaborating institutes! Latest version (and history) online

Responsible persons Mechanics  I. Gfall Cooling & Services  A. Frankenberger End flanges, support shell  KEK? Electronics  C. Irmler, M. Friedl Ladder assembly  C. Irmler, Y. Onuki –L3, L4  India, Melbourne? –L5  Vienna, C. Irmler –L6  IPMU, Y. Onuki Sensors –Barrel sensors, HPK  T. Tsuboyama –Trapezoidal sensors, Micron  T. Bergauer Mockup  KEK? –who is responsible for which mockup?  need detailed information SVD assembly and installation –all groups –is not very detailed now 3Christian Irmler (HEPHY Vienna)23 July 2012

Mechanics – Ladder design Design of L4-6 has been fixed in March L3 design was critical task at March B2GM L3 solved now –Immanuel will present actual design –minor changes possible –improvement of APV cooling 4Christian Irmler (HEPHY Vienna)23 July 2012

Mechanics – End mounts Several designs (sliding mechanism / pin + screws / mixture) First prototypes available Evaluation & improvements SLM requires high precision Details  I. Gfall 5Christian Irmler (HEPHY Vienna)23 July 2012

Mechanics – CF parts Cooperation with IFCA / INTA –MoU not signed yet  costs! Ribs –use ready-made sandwich for ribs –MPI offered to assist, will try to mill ribs out of CF sandwich plate Cones –other CF manufacturer –can they made from metal? 6Christian Irmler (HEPHY Vienna)23 July 2012

Mockup Above schedule is a rough estimation. Needs to be defined in detail! Who is responsible? Work can be started, after (almost) final design has been fixed. 7Christian Irmler (HEPHY Vienna)23 July 2012

Cooling services & APV cooling Design in progress Details by Immanuel First prototypes in autumn 8Christian Irmler (HEPHY Vienna)23 July 2012

Front-end electronics prototypes successfully tested 9Christian Irmler (HEPHY Vienna)23 July 2012 design in progress prototypes available designed but yet not ordered prototypes tested  ok design very similar to +z L4-6  soon!

Back-end electronics Slightly postponed to speed up front-end design. Level translation daughter boards ready and tested. Controller board, FADC mainboard and FPGA daughter board will be designed soon. Prototypes scheduled for 1 st quarter 2013 Firmware development will be done once HW is designed (~ beginning of 2013) Details will be presented by Markus. 10Christian Irmler (HEPHY Vienna)23 July 2012

Sensors 11Christian Irmler (HEPHY Vienna)23 July 2012

Sensors 12Christian Irmler (HEPHY Vienna)23 July 2012 Micron DSSD –expect final prototypes end of July –will be tested in a combined beam test & irradiation in October 2012 –Need to be ordered in Dec (as soon as beam test results are available!) L3 sensor –should be specified & ordered from HPK soon. Please send me detailed information about HPK delivery plans!

Ladder assembly Detailed plan for L5 Need detail plans for other layers! Production can / must start in summer 2013! 13Christian Irmler (HEPHY Vienna)23 July 2012

SVD assembly & installation (preliminary) Many dependencies –ladder production –mechanics –global schedule We are still within the baseline schedule (physics run from end of 2015) 14Christian Irmler (HEPHY Vienna)23 July 2012

Thank you 15Christian Irmler (HEPHY Vienna)23 July 2012
