  5. Formation of the LCTPC/LP collaboration The proposal is to have: 1)Three coordinators, one chosen by each region. These spokespersons (SP) coordinate the work of the following two boards: 2)The collaboration board (CB), consisting of one representative from each group or set of groups (the group leader, principle investigator or other chosen member). Each CB member looks after the resources for its group(s) (money and people). 3)The technical board (TB), consisting of the existing workpackage (WP) conveners. The TB will ensure the technical integrity of their WP and compatibility with other WPs while maintaining close contact with the collaboration. This structure now exists. 1) We are three interim coordinators and are to be replaced by chosen ones in the course of this formation phase. 2) The CB is (almost) complete. 3) The workpackages and WP conveners were identified during the first half of this year. The names of CB and TB members are listed in the next slide. Ron Settles MPI-Munich/DESY 8th WP phonemeeting 30 August 2006

  9. AGENDA • -1a.Formation of the LCTPC/LP collaboration We shall be sending an email this week on the next steps for the formation of the LCTPC/LP collaboration… Ron Settles MPI-Munich/DESY 8th WP phonemeeting 30 August 2006

  10. AGENDA -1b.Tracking review at Beijing: As announced at the VLSW06, the WWS-R&D Panel is starting regular reviews of the different R&D projects for the LC detector. Chris Damerell has sent the email that they want to start with tracking (Si and TPC) at the Asian LC meeting in Beijing (3-7 February 2007). The modus operandi is still being discussed… Ron Settles MPI-Munich/DESY 8th WP phonemeeting 30 August 2006

  11. AGENDA -1c.PIRE As announced by Dan, this is the “Partnerships for International Research and Education” program at Cornell. More details from Dan… Ron Settles MPI-Munich/DESY 8th WP phonemeeting 30 August 2006

  12. AGENDA -2a.Next iteration on the goals for LCTPC/LP. For your info: we (Fabio Sauli, Madhu Dixit, Martin Killenberg, Akira Sugiyama, RS, a.o.) have started on thinking about ways to test Gem gating with (a) small prototype(s). Martin thinks we might have a scheme that works, but it has to be tried out. If you are interested or have suggestions, let us know… Ron Settles MPI-Munich/DESY 8th WP phonemeeting 30 August 2006

  13. AGENDA -2b. Gem endplate (a.o.) for the LP Akira (WP convener for the LP Gem endplate) sent a mail asking which groups want to participate in the work of making/testing the Gem endplate(s) for the LP. The division of work among groups will be a part of the general organization of the LCTPC/LP collaboration which has to be done within the next few weeks. For the Gem-endplate question, more from Akira… Ron Settles MPI-Munich/DESY 8th WP phonemeeting 30 August 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 8th WP phonemeeting 30 August 2006

  36. 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.
