1. EUDET Networking Activity 2 “Detector R&D Network”
- What is NA2?
- NA2 tasks
K. Desch, University of Freiburg 1

2. What is NA2? Objectives (from Annex 1, description of work):
create a network of European institutions which are participating in ILC detector R&D
ensure close cooperation
provide common framework for exchange of information
This is rather abstract – individual sub-tasks are
much more specific
Needs openness and contribution of all JRAs to make it a success
NA2 goes beyond EUDET – build on existing activities
Had a first brainstorming meeting in Dec 06 to see how to fill this with life 2

3. NA2 structure 6 Tasks: COMP Dedicated Computer Cluster
ANALYS Software Framework
WEBINFO Web-Based Information System
VALSIM Improve modelling of hadronic showers
MICELEC Facilitate access to deep sub-micron technologies
EXCHG Annual EUDET workshop & Mutual visits 3

4. COMP – Computer Cluster
Coordinator: P. Wienemann, Freiburg
Contributing Institutions: DESY, Freiburg, Prague, Tel Aviv
Scope:
- Contribute the EU-funded resources to the ILC-VO in the LCG-Grid
- Make sure they are available for EUDET related work, though
- No need to setup sth. EUDET specific, integrate with world-wide activities
- Facilitate the use of resources
( introduction by R. Poeschl on Friday)
- Work on setting up web-based file catalogues, ‘standard’ job templates
production system (limited person power) 4

5. COMP – Computer Cluster
Status of VO ILC:
Quite significant resources already available – Make use of them!
Snapshot CPU on 14/02: o(1000) free CPUs (often shared with other VOs, mainly LHC experiments)

7. ANALYS – Analysis + Software Framework
Coordinator: F. Gaede, DESY
Contributing Institutions: DESY(~75%), Freiburg(~20%), Prague(~5%)
Scope:
Development of a common data analysis and simulation infrastructure
- framework to exchange and compare testbeam data
- allow for common data analysis
- creation of data repository
We cannot + should not do this alone - We should not reinvent wheels
EUDET effort should completely integrate with ILC software work
Basis to start + further develop + make usable for testbeam analysis:
Existing ILC software packages at ilcsoft.desy.de 7

8. ANALYS – ILC software packages
from F. Gaede 8

9. ANALYS – ILC software packages
from F. Gaede 9

10. ANALYS – ILC software packages
It is important for EUDET JRAs to make use of the packages as much as possible
Testbeam times = hectic times
 start implementation for prototype detectors early
 try to withstand the temptation of ‘quick&dirty’ hacks
Development of working tools depends critically on active feedback and participation from the JRA’s and testbeam users in general
Common software session on Friday at 9h 10

11. WEBINFO – Web-Based Information System
Coordinator: H. Abramowicz, Tel Aviv
Contributing Institutions: Tel Aviv University (+ all !)
Scope: (twofold)
1. Outside visibility of the project
2. Portal for EUDET-internal information
(documentation, meetings, link to data,…)
Again: avoid doubling of work/information
If a good information structure is already existing elsewhere (which also
might have a broader scope than EUDET, e.g. CALICE) information should
stay there – but links to and from EUDET pages desirable 11

12. WEBINFO – Web-Based Information System
A first version of is online (thanks to Yan Ben Hammou, TAU)
based on the plone CMS 12

13. WEBINFO – Web-Based Information System
Some Questions
- meeting agendas: central system? where? which one? or just a collection of links?
- user-editable project pages? authentification?
- how to keep the (sub-)pages up-to-date? responsibilities?
Parallel meeting on Friday, 9h (video-conf room in Bldg 2b)
All JRA’s should be represented and come up with questions + suggestions 13

14. VALSIM – Modelling of Hadronic Showers in G4
Coordinator: J. Apostolakis (CERN)
Contributing Institutions: CERN
Scope:
Improve the simulation tool’s modelling of hadronic showers (GEANT4) and create the validation tools for fine-grained calorimeters.
Obviously, this is highly related to the JRA3 objectives.
My view: this task (although formally in NA2) should be coordinated
within JRA3 14

15. VALSIM – Potential work items
(from John Apostolakis):
- Verification of physical processes
- Review of physical processes for key detector materials (Verification)
Materials: Si, W, gases (Ar, CO2, CH4, CF2), ...
- Verification for key processes in relevant materials (using thin target data)
- Comparison/validation of detailed interaction products d2/dE d in particular for hadronic interactions
- Benchmarking of neutron modeling
- Key aspects of use cases: neutrons as background, activation, hazard/shielding.
- Identified/candidate benchmarks
- Review / update data for data-driven neutron modelling (E<20 MeV)
- Radiation effects in silicon: joint investigation with space community
- Radiation and effects on endcap detectors 15

16. VALSIM – Potential work items
(from John Apostolakis):
- Hadronic shower development
- Neutron, EM, charged fractions
- Hadronic shower shape: comparisons with data and regression testing
- Effect of hadronic interactions in ECAL
- Effect of choice of physics models, Assessing strengths/weaknesses of available physics lists
- Other/Technical aspects
Not all of these can be realized within EUDET
Need to define priorities 16

17. MICELEC – Access to deep-subµ technology
Coordinator: A. Marchioro (CERN)
Contributing Institutions: CERN
Scope:
Facilitate access to deep submicron technologies for radiation-tolerant microelectronics developments for front-end and readout ASICs.
Design support and ILC coordinated access to a commercial silicon foundry for prototyping and production of integrated circuits in deep submicron CMOS technologies will be provided.
A user (JRA)-driven task. Make use of the offer! 17

18. MICELEC – Why a common service
(From A. Marchioro):
The entire HEP community is, even if agglomerated, only a very small customer of a modern foundry
Total LHC volume (over 5 years) was about 2 days of production of a medium size supplier
Cost of newer technology is increasing very fast
¼ mm 1 X, nm 4-5 X, nm 9-10 X
Majority of designs in community are not “commodity” design
Most HEP chips are Analog and Mixed Signal
Most chips require special care for rad-tolerance 18

19. MICELEC – Support Technical:
- Validation of rad-tolerant technologies and design techniques
- Libraries, design kit, tools, training and design guide-lines
- Sharing of resources (e.g. general purpose layout for special devices, analog and digital blocks)
Commercial:
- Organization of contract for entire HEP community to support ¼ mm, nm and 90 nm CMOS technologies
- Negotiation of common tools and IPs from third party vendors
- Global Non-Disclosure-Agreement framework for entire community whenever applicable
- Price competitive or below other silicon brokerage services
- More flexible prototyping
- Contract to cover possible commercial fall-out developments
Submission and post-design support 19

20. MICELEC – Projects
Timepix chip for Pixel readout of GEMs/Micromegas TPC
Prototype R/O chip for SILC
Modified ALTRO chip for pad TPC readout … 20

21. DAQ Not a formal task in NA2
Needs coordination & interaction of JRAs anyhow
First discussion on plans on Friday, 9h –
Interested people, please join! 21

22. Information Mailing list: eudet-na2@desy.de is existing
Should contain all names contributing to NA2
Interested people from JRA’s are encouraged to subscribe!
Send to
Do we need dedicated JRA contact persons (so far communication through JRA AC’s) ?
Mailing lists (in general):
Activities have mailing lists
DESY system tedious to maintain – look for alternatives? (e.g. CERN SIMBA) 22

23. Summary Networking activities are an important part the EUDET project
- Keep and improve contacts among ourselves and worldwide
- Establish common computing infrastructure (hard- and software)
- Tools for information flow
- Common hardware projects (Microelectronics, DAQ,…) 23
