DANIEL HAAS, CHIPP WORKSHOP ZÜRICH, SEP 2006

Outline



• Goal: Create infrastructure to support R&D for International Linear Collider

• 6th framework program of EU• Timeline 2006-2009• 31 european partner institutes, 20 associates

EUDET Overview



• The next big thing after the LHC:

• 0.5~1 TeV e+/e--collisions• Precision measurements

of LHC ‘discoveries’• Strong support from

Europe and CERN• Ready for construction:

2010• Start 2012-2015??

International Linear Collider

• e+e- LC operating from MZ to 500 GeV

• e- /e+ polarization • at least 500 fb-1 in

the first 4 years• Upgrade: to ~ 1 TeV

500 fb-1 /year



Final goal for inner pixels:• 5 cylindrical layers:

– R = 15 – 60 mm– |cosθ| < 0.9 – 0.96

• Ultrathin layers– 0.1% X0 / layer (50µm)

• Fast R/O (25 – 50 µs)• 300 – 800 Mio Pixels• Low power

– < 100W

EUDET Activities

QuickTime™ and aTIFF (Uncompressed) decompressor




Networking ActivitiesVery important part of the project!• Information exchange and intensified collaboration:

– web based information system– annual workshops– open for everyone!

• Common simulation and analysis framework:– development of common software framework (testbeam analysis &

ILC simulation)– small grid based computer cluster

• Validation of simulation:– e.g. Geant4 shower simulation

• Deep submicron radiation-tolerant electronics:– access through CERN contracts



Transnational Access• integral part of I3 to open trans-European access to

research facilities• perhaps not really necessary in High Energy Physics, we

are used to it• but, we could take advantage of it:• some travel support for European groups

– using the DESY testbeam (as of 2006)– using the EUDET infrastructures as soon as available (≥ 2008):

• beam telescope

• TPC

• Si TPC

• Si tracking

• calorimeter



Joint Research ActivitiesJRA2: Tracking Detectors• Large TPC prototype:

– low mass field cage (for JRA1 magnet)

– modular endplate system for large surface GEM & µMegas systems

– development of prototype electronics for GEM & µMegas

• Silicon TPC readout:– development MediPix → TimePix

– TPC diagnostic endplate module incl. DAQ

• Silicon tracking:– large & light mechanical structure for Si strip detectors

– cooling & alignement system prototypes

– multiplexed deep submicron FE electronics



Joint Research ActivitiesJRA3: Calorimeter• ECAL:

– scalable prototype with tungsten absorbers– Si-sensors & readout chips

• HCAL:– scalable protoype– multi-purpose calibration system for various light sensing devices

• Very Forward Calorimeter:– laser-based positioning system– calibration system for silicon and diamond sensors

• FE Electronics and Data Acquistion System for the calorimeters



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– DAQ system

• Note: all EUDET infrastructure is movable– construction & initial tests at DESY– later exploitation at CERN, FNAL etc. possible



JRA1 - Tasks• Infrastructure: Ingrid Gregor (DESY)• Magnet: Katsumasa Ikematsu

(DESY/KEK/CERN)• Pixel Telescope: Wojciech Dulinski

(Strasbourg)• DAQ: Daniel Haas (Genève/

Mannheim/Bonn/INFN)• Validation: David Cussans

(Bristol/Bonn/MPI)

PCMAG



JRA1 - General Purpose Infrastructure

• Generally applicable:• use for pixel sensors, large volume tracking

devices (TPC), other areas (imaging, biology, medical)

• large range of conditions (cooling, positioning, magnetic field)

• easy to use• Well defined/described interfaces• very high precision• < 2µm precision even at smaller energies • suitable to different test beam environments,

rates, energies, …



JRA1 - Pixel Telescope• Pixel telescope with sensors that

– provide high precision (~ 2 – 4 µm)

– with reasonably large area (~ 1 – 2 cm)

– can be thinned down (~ 100 µm)

– can be read out (relatively) fast (~ kHz)

• Start with an existing CMOS MAPS chip– Mimostar 3 by CNRS/IRES

(not fast enough, 10-100 Hz)

• then go to next generation chip which is fast:– … on chip discriminator

and ADC

Trigger



JRA1 - DAQ• Synchronization via

common TLU• Digitization/Sparsification

with dedicated HW or commodity equipment (USB interface)

• SW level integration with standard interfaces



JRA1 - Trigger Logic Unit

QuickTime™ and aTIFF (LZW) decompressor


• Simple Handshake via Trigger/Busy/Reseton RJ45 LVDS lines (or TTL-Lemo)

• Timestamp and event-number via USB• Eventnumber via advanced data handshake on

RJ45 available

• In collaboration with Bristol



JRA1 - DAQ Software• Reuse - don’t reinvent• Combine:

– Existing DAQ from Bonn for DUT– Existing readout for Strasbourg hardware– Bristol library for TLU

• Added functionality:– creation of ROOT-files from binaries

• Upcoming functionalities:– Data reduction (CDS and Clustering)– Tracking (via Kalman-filter)– multi-PC acquisition, platform independence (?)



JRA 1 - DAQ Planning



Common DAQ effortsDAQ 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



Upcoming events• EUDET annual review, 18-20 Oct 2006

– Review of tasks– Deliverables for EU-contract– Report to EU

• Delivery of a Pixel Telescope Demonstratorin July 2007– not all pixel planes, basic DAQ, reduced rate

• Final (fully working) telescope needed in 2009



Conclusions• EUDET program is fully incorporated in the

ILC detector R&D, giving additional funding on international scale

• BUT: EUDET is a contract between us and the EU with well defined milestones and deliverables

• Geneva is providing DAQfor JRA1 pixel telescopeand is well on track
