  3. AGENDA -1a.News • Formation of the LCTPC/LP collaboration: • Email from Rolf Heuer (26June/4July) announcing the start of steps towards a more formal structure for our work which is necessary, for now in order to properly plan and execute the LP work, and for later to make the transition to building the LCTPC itself. • He has asked a small committee of one person per region (Dean Karlen, Takeshi Matsuda and Ron Settles) to prepare a proposal for the organization of the LCTPC/LP collaboration. • They would appreciate it if you would send your opinions on the structure of the collaboration within one week. • The proposal will be circulated around the middle of next week (12 July), in time for a continuation of the discussion at the LCTPC meeting in Vancouver.: Ron Settles MPI-Munich/DESY 4th WP phonemeeting 6 July 2006

  4. AGENDA -1b.News • www.lctpc.orgis working in principle. At the moment is simply linked tohttp://www.mppmu.mpg.de/~settles/tpc/welcome3.html until I have finished. From there click on LP, then e.g. WP meetings, then e.g. to today’s meeting. I have cleaned up my website, and the setup for the workpackages is almost done. There I will try to keep all of the relevant files/information. Take a look and let me know if there anything is missing… Ron Settles MPI-Munich/DESY 4th WP phonemeeting 6 July 2006

  20. AGENDA -6.Future meetings Since the ideas are very diverse at the moment we need rather frequent 1-hour phonemeetings to work through the options. Next: Next week?,then 18July(Vancouver) -At Vancouver, we will discuss the LCTPC collaboration, the WP and in addition decide frequency of next phonemeetings. After Vancouver there are (in addition to phonemeetings): -Paris, WP1 workshop? (between 4 and 15 September) -Eudet annual meeting MPI-Munich (18-20 October) -Valencia LC workshop (6-10 November) Ron Settles MPI-Munich/DESY 4th WP phonemeeting 6 July 2006

  35. Some features • Zigzag structure prevented loss of tracks > θ~22° • Sectors mounted from inside using a “handling tool” • to minimize the dead space between sectors. This • straight-forward operation which was performed • at least 30 times during the lifetime of Aleph. • Alu sandwich structure stiff, lightweight to • - contain 7mb overpressure • - provide forced-air thermal insulation • between electronics and TPC volume • Water cooling of 1kW electronics/side in addition • - 22K channels per side • Combination water/air cooling blocked all heat to TPC • Overall thickness ~ 25%Xo (average) w/o cables • Bending of endplate • 20 micrometers due to 7mb overpressure • 5 micrometers due to wire tension Ron Settles MPI-Munich/DESY 4th WP phonemeeting 6 July 2006

  37. R&D Planning • 1) Demonstration phase • Continue work with small prototypes on mapping out parameter space, understanding resolution, etc, to prove feasibility of an MPGD TPC. For CMOS/Si-based ideas this will include a basic proof-of-principle. • 2) Consolidation phase • Build and operate the LP, large prototype, (Ø ≥ 75cm, drift ≥ 100cm), with EUDET infrastructure as pedestal, to test manufacturing techniques for MPGD endplates, fieldcage and electronics. Design is starting---building and testing will take another ~ 3 years. • 3) Design phase • After phase 2, the decision as to which endplate technology to use for the LC TPC would be taken and final design started.
