    • 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

Organizational progress

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


Brainstorming results 1

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

Brainstorming results 2

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

What should demonstrator demonstrate

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


Magnet

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

Desy test beam area

DESY Test beam area

Testbeam 24

EUDET JRA2 Brainstorming, 4 January 2005


Magnet @ desy

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

Open questions

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?
