2 ILC Physics Precision Terascale elementary particles well defined: energy angular momentum uses full CoM energy produces particles democratically can mostly fully reconstruct particles LHC will lead the way, ILC will have a 2nd, more precise look Page 2

4 ILC Design & Goals E CM adjustable between GeV Int. Luminosity ~500 fb -1 in 4 years Energy stability/precision below 0.1 % Electron polarization of at least 80% 2 Detectors, maybe in push-pull! Cost estimate: ~6.6 Billion (machine only) Page 4

5 EUDET Overview Goal: Create infrastructure to support R&D for International Linear Collider 6th framework program of EU (21 M, 7 M from EU) Timeline Feb 06) 31 european partner institutes, >20 associates Page 5

6 EUDET Activities Page 6

7 Calorimeter 33% Management 4% Tracking 33% EUDET Budget Networking 9% TA 2% Magnet & Pixel Telescope 18% most of the resources for the development of the infrastructures ramp-up first half 2006 full swing activities for 2.5 years last year: phase-out and exploitation of infrastructures Page 7

8 JRA1 - Testbeam Infrastructure Large bore magnet: 1 Tesla, Ø 85 cm, stand-alone He cooling, supplied by KEK infrastructure (control, field mapping, etc.) through EUDET Pixel beam telescope 4-6 layers of MAPS detectors CCD and DEPFET pixel detectors for validation, maybe TPC easy-to-use DAQ system incl. Trigger Logic Unit Note: all EUDET infrastructure is movable construction & initial tests at DESY exploitation at CERN, FNAL etc. possible Page 8

9 Pixel Telescope Box 1 Box 2 y x z Box 3 (DUT) Up to 6 telescope planes DUT is moveable via X-Y-Table Cooling can be provided Flexible telescope geometry High resolution planes close to DUT possible Carsten Muhl (DESY) Page 9

10 Sensor Boxes Carsten Muhl (DESY) 3 planes on one main structure Each has different geometry depending on position Each plane movable individually with small tool Minimal distance between planes: 7mm Maximum lever arm: 200 mm Material: aluminum All material non-magnetic Materials were optimised for minimal thermal stress Page 10

11 MAPS technology: Baseline Sensor: MIMOTEL 256x256, 30 µm pitch, 7.6x7.6 mm 2 HR tracker 512x512, 10 µm pitch, 5x5 mm 2 Initial Sensor Page 11

12 Final Sensor (end 2008) extension of Mimosa 22+ integrated zero suppression column // readout 1088 columns of 576 pixels (20.0x10.5 mm 2 ) Readout time ~ 100 µs thinned sensor High rates and low data volume possible Full exploitation in 2009 for users possible Page 12

13 Performance Standard setup gives ~2 µm resolution HRT can go as low as ~1 µm Low energy dominated by multiple scattering Mimotel Mimotel + HRT Page 13

14 The Demonstrator 3 to 6 sensor planes Mimotel sensors (256x256, 7.6x7.6 mm) 2 tests (@DESY) with 3 and 5 planes to: qualify the concept test the DAQ measure sensor performance Current DEPFET (and later SILK) as first users Page 14

15 Readout Hardware by INFN Ferrara mother board built around an ALTERA CycloneII FPGA (clock rate: 80MHz) and hosting the core resources and Interfaces (VME64X slave, USB2.0, EUDET trigger bus) NIOS II, 32 bit soft microcontroller (clock rate: 40Mz) implemented in the FPGA for on board diagnostics on-line calculation of pixel pedestal and noise remote configuration of the FPGA via RS-232, VME, USB2.0 Two readout modes: Zero Suppressed readout to minimize the readout dead-time while in normal data taking. Non Zero Suppressed readout of multiple frames for debugging or off-line pedestal and noise calculations analog daughter card based on the successful LEPSI and SUCIMA designs clock rate up to 20 MHz digital daughter card drives/receives control signals for the detectors and features a USB 2.0 link Page 15

16 JRA1 - Trigger Logic Unit Simple Handshake via Trigger/Busy/Reset on RJ45 LVDS lines (or TTL-Lemo) Timestamp and event-number via USB Eventnumber via advanced data handshake on RJ45 available In collaboration with Bristol Page 16

17 Key: Application Buffer DAQ-Architecture JRA1 Thread Signal /data Listening Socket Command Data Logging Page 17

18 JRA1 DAQ Features Platform independent (Linux, MacOS X, Windows under Cygwin) and highly modular current suite of ILC software (LCIO/Marlin etc) also runs under MacOS, but no official support yet DUTs could (and should) be easily integrated in our DAQ, simple examples and help will be provided First users currently at CERN testbeam: (DEPFET from Bonn) SVN Repository and Documentation at: Page 18

19 Testbeam results From 1st DESY Testbeam 3-6 GeV electrons 200 GB (!!) of raw data on disk (2 MB/event) All raw data have been converted to LCIO format, pedestal corrected, scanned for clusters and transformed to space points Data have been moved to tapes and are available to ILC virtual organisation members through the GRID Data processing has been done using the GRID infrastructure as a proof of principle for future and more compelling data challenge Page 19

20 Testbeam results 3x3 cluster distributions telescope hit map Page 20

21 Testbeam results 2nd DESY testbeam (August), 5 planes Page 21

22 Testbeam results 3rd testbeam at CERN since yesterday at SPS (high energy, so low multiple scattering, main disadvantage of DESY tests) Setup in barrack completed, first dry run succesful Waiting to move the telescope into the beam DAQ upgraded with disks (4 TB in RAID x400 GB system disk) Page 22

23 Common DAQ efforts... DAQ has been identified as key issue of EUDET part of the infrastructures easy-to-use for users cross-jra issue combined testbeam run of several sub-detectors relations to software framework ( NA2) DAQ is also an important issue for ILC detectors EUDET is not going to design/build anything close to the final ILC DAQ system but we must stay connected to the international R&D efforts to go into the same direction Page 23

24 ...Common DAQ efforts Conclusions from DAQ group discussions (March 07): JRA1 to JRA3 will keep independent DAQ systems in the beginning JRAs will try to use common TLU for triggering JRAs will (try to) use LCIO as data format Common DAQ session at Paris annual meeting (Oct.) Page 24

25 Conclusions EUDET Pixel telescope to qualify detector technologies for Vertex detectors (and others) High resolution and reasonable readout frequencies for most R&D Demonstrator available NOW DUT integration at any level possible Final telescope end of 2008 Free choice of the beam, system is portable Geneva contribution: Modular/platform independent DAQ with high data throughput Page 25
