  1. JRA1 – JRA2 Interface Tobias Haas DESY 4 January 2006

  2. JRA 1 Status • Brainstorming 3/4 Nov. @ DESY • Coarse outline of the project • First WBS • Results documented: • http://www-zeus.desy.de/~haas/eudet-jra1/ • DAQ workshop 14/15 Dec. @ CERN • Detailed WBS with milestones and deliverables up to middle 2007 EUDET JRA2 Brainstorming, 4 January 2005

  3. Organizational Progress • JRA1 Tasks and leaders: • Magnet → Katsumasa Ikematsu (DESY) • Telescope Sensors → Woijciech Dulinski (Strasbourg) • Telescope Integration → Ingrid Gregor (DESY) • DAQ → Daniel Haas (Genève) • Validation → David Cussans (Bristol) • Next Dates: • Meeting: 3 February (1 week before EUDET Kickoff) • MAPS Tutorial: 14 – 17 March, Strasbourg • Review 1: 4 April, CERN • Review 2: January 2007 • Review 3: July 2007 EUDET JRA2 Brainstorming, 4 January 2005

  4. Brainstorming Results 1 • Telescope layout and configuration: • A transverse size of ca 2 cm will be provided at least in one direction. The second direction can be smaller. • The longitudinal layout will be configurable and should provide at least two configurations: a very compact one (ca. 20cm) and a two-arm one with space for a larger DUT in the middle. The mounting will be such that at least one plane can be brought very close to the DUT in the compact configuration • Precision positioning for a pixel DUT will be built • Telescope chip • A CMOS Maps will be used for the telescope. • The telescope chip will have a discriminator and ADC on board • Frame R/O time will be of the order of 1 ms EUDET JRA2 Brainstorming, 4 January 2005

  5. Brainstorming Results 2 • Cooling • The temperature of the DUT must be able to be kept constant. What temperatures are needed is still open • DAQ • Telescope and DUT DAQ will be kept separate. The interface is via trigger, busy and event number. (TLU provided) • The telescope F/E will do digitization and sparsification for the demonstrator. • R/O should be over a standard interface such as USB-2 • Demonstrator (available middle 2007) • The demonstrator should be a fully usable system • It will use the MIMO* 3 chip with the MIMOSA 5 as a fall back solution EUDET JRA2 Brainstorming, 4 January 2005

  6. Compact: for pixels DUT 5mm Magnet Two-arm: TPC etc… In a magnet: DUT Magnet Planned layout 6 Telescope planes usable in different configurations: EUDET JRA2 Brainstorming, 4 January 2005

  7. What should Demonstrator demonstrate? • Show the principle: • Sensors • Demonstrate the precision • Compromise on size and DAQ integration • Mechanics/Integration • Demonstrate overall setup/flexibility • Could be one out of two arms • DAQ • Fully functional • Compromise on the rate (~10Hz) • DUT • Should be fully functional for Pixel devices • Compromise for other users (TPC) EUDET JRA2 Brainstorming, 4 January 2005

  8. Magnet • Superconducting solenoid from KEK: • B ≤ 1.2 T • 85 cm bore • 246 cm long • To be operational @ DESY by end 2006 • Limitations: • Stray field  interlock • He cost  length of operation EUDET JRA2 Brainstorming, 4 January 2005

  9. DESY Test beam area Testbeam 24 EUDET JRA2 Brainstorming, 4 January 2005

  10. Magnet @ DESY • Place magnet in one of the two EAs in beam 24 • Slight preference for B • Area A available for parallel non-B expt. • Cryo and controls outside EA which is interlocked Stray Field EUDET JRA2 Brainstorming, 4 January 2005

  11. Open Questions • What do you expect of us? • How much lateral movement? • Beam or DUT? • Do you need the telescope? • In front, behind or both? • What information from the telescope? • Move magnet to other beams? • Information exchange • Contact person on either side?
