4. The proposed solutions ECAL : Sampling calorimeter Solution 1 : tungsten(density) - silicon(pixel size ~ Molière radius) Solution 2 : tungsten -MPPC and scintillator tile/strip Pixels size <1cm² and about 20-30 readout layers (15 to 250 Millions channels) HCAL Solution 1 : Sampling calorimetertungsten/Stainless steel(density) –digital readout (pixel size) Solution 2 : Sampling calorimetertungsten/Stainless steel(density) – scintillator tile (small size) Pixel size 1cm² and about 50 readout layers (~50 Millions channels) Pixels size 16cm² and about 50 readout layers readout by silicon PM !! J.-C. Brient (LLR)

5. Our plans A first generation prototypes, which allows to debug the concept and technologies 2001 - 2005 A second generation prototypes, much closer to the final detector 2006 - 2009 Ready for LOI, Proposal etc… in 2010 !! J.-C. Brient (LLR)

6. First generation prototypes • ECAL ready and in use at test beam • Tile HCAL using SiPM from Russia ready and in use at test beam • Digital HCAL in plan ( waiting for funding !!!) J.-C. Brient (LLR)

7. DETECTORS MATRIX ECAL Czech Russia Korea AND • Brazil (Unicamp-Sao Paulo) • BARC - India Hamamatsu not in the list !! (already some contact , but only with Hamamatsu-France) J.-C. Brient (LLR)

18. Next steps • Test with electron (may be small energy hadron) • test of running with the VFE chip INSIDE the detector • Test beam with AHCAL+ECAL for debugging • and … single layer test (new design) … • Test with Hadron CERN ?? Summer 2007 MTBF Fall 2007 • Use EUDET funding for the construction of ½ ECAL module • with all news developments + Possible Digital HCAL module 2008 – 2010 Second generation prototypes in test beam FNAL ? may be the right time for an alternative ECAL with MPPC and scintillator strips ? J.-C. Brient (LLR)

19. Second generation prototypes • Tile HCAL , ECAL in design , R&D in progress • Digital HCAL in plan ( waiting for funding !!!) (LAL, LLR, LAPP, IPNL, IHEP-Protvino, and CIEMAT ??) J.-C. Brient (LLR)

20. Second generation ECAL prototype Concept : to be the most representative of the final detector module : • A alveolar composite/tungsten structure with : - same W sampling - 3 columns of cells to have representative cells in the middle of the structure (with thin composite sheets ) - Identical global dimensions (1.5m long) and shape (trapezoidal) - fastening system ECAL/HCAL (include in the design of composite structure) • 15 Detector slabs with FE chips integrated - 1 long and complete slab (L=1.5m) - 14 short slabs to obtain a complete tower of detection (typ. L=30 cm?) and design of compact outlet. Fastening system Alveolar Structure C/W 3×15 cells Short detector slabs (14) Long detector slab (1) Complete Tower

21. Example of R&D NEW DESIGN for the ECAL Detector Slab • Better for mechanical behavior • Better Molière radius • Better for indust. assembling • DAQ based on FPGA • better for VFE • etc… Tested at industrial level J.-C. Brient (LLR)

Brient (LLR)

23. Tail Catcher HCAL Electronics Racks ECAL Beam Possible setup at FNAL MTBF J.-C. Brient (LLR)

24. Conclusion • Due to the lack of funding and Manpower , sharing is a necessity and therefore CALICE is just MANDATORY !! • It is a NO-LOOSER collaboration (at the time of decision, everybody will be already in the good boat) • the progress is important (test beam) and the road map is well established Negative point • LARGE labs are still missing in the collaboration (CERN, FNAL, KEK , LBL ) J.-C. Brient (LLR)

25. A major lab is mandatory to organise and manage the work on the silicon wafers for the ECAl W-Si > Discuss with large producers like Hamamatsu !! > Define the protocol of the data quality control (existing expertise and engineering structure and people) > Manage the sharing between smaller labs > … J.-C.
