Status of the LCTPC/LP collaboration(slides#3,4,5,6) The RC for American is Dean Karlen, for Asia is Takeshi Matsuda and for Europe the search committee (Klaus Desch and Vincent Lepeltier) is still working and want to have a result by Valencia. The LCTPC meeting at Munich was attended by the following colleagues: Ties Behnke, Klaus Desch, Ralf Diener, Keisuke Fujii, Lea Hallermann, Michael Hauschild, Leif Jonsson, Dean Karlen, Alexander Kaukher, Vincent Lepeltier, Takeshi Matsuda, Joachim Mnich, Dan Peterson, Peter Schade, Oliver Schaefer, Ron Settles, Jan Timmermans, Adrian Vogel The discussion centered around the next general steps to be undertaken by the collaboration: (1)LP1 construction --Definition of tasks for building LP1 with time table --Establish which groups have the resources to contribute to the LP1 construction-->this requires setting up an overview of the money/manpower situation of all groups --Distribution of tasks for LP1 among all groups --Figure out what to do if something is missing --Set up a simple (loose) MOA for the LP1 construction (2)LCTPC R&D --Continue defining the overall four-year program of R&D needed for the LCTPC --Identify the R&D tasks to be covered by LP1->LP2, SP, simulation studies --See how the tasks can be distributed among the groups --Figure out what to do if something is missing (3)Beijing Review --This will probably consist of a written report before Beijing and several talks at Beijing. --Identify a task force for putting together the written report --There will be an open session on the R&D status and a closed session on the funding situation. --Find out who is going to Beijing from the LCTPC groups to see who can give which talks. There may be some reports by telephone. 1b. WWS-R&D-panel tracking review at Beijing (slides#7.8.9) The mail sent by the WWSOC to all the ILC mailing lists in America, Asia and Europe is between the rows of ****: ************************ From richard@lal.in2p3.fr Tue Oct 24 17:50:55 2006 Date: Fri, 20 Oct 2006 15:05:52 +0200 From: Francois Richard To: ecfa_desy-lc@desy.de Subject: World-wide reviews of ILC detector R&D Dear colleagues, We write to inform you of a new responsibility we are giving to the WWS Detector R&D Panel, namely to implement a systematic procedure for peer-reviewing ILC detector R&D on a world-wide basis. This new system is intended to put the detector R&D on a more even basis with ILC accelerator R&D, which is already organised by the RDB (the Research and Development Board of the GDE) into world-wide task forces. Detailed plans are still being finalised, but the general procedure will be as follows. The Panel, operating within the existing structure of regional workshops, will organise the review of one set of topics at each workshop, starting as follows: Beijing (Feb 2007)--tracking, DESY (LCWS) (June 2007)--calorimetry, Fermilab (October 2007)--vertexing and Asia (tbd 2008)--particle ID, muon tracking, solenoid, beam diagnostics and DAQ. By cycling through the four sets of topics in this way, over time each region will host every topic. To help with the peer review process, we plan to invite impartial experts from outside the ILC community, as well as members of the Detector R&D Panel. Each review will start with an open session, followed by a closed session on the next day. Every group will be invited to present a status report on their work, including past and future milestones, through to completion of their R&D goals. For these purposes, a 'group' will be taken to mean any R&D activity covered by agreements with funding sources in one country. This means that there would be, in general, one report per country for a collaborative effort involving more than one country. A programme within EUDET will also be considered a group. Large collaborations such as LC-TPC or CALICE may wish to organise their open session presentations in the form of an extended introduction, followed by presentations from each of their constituent groups, who will explain what R&D plans are covered by their national resources. In the closed session, each group will have the opportunity to discuss funding issues and other possibly confidential matters related to achieving their milestones. After the closed session, the reviewers will write a report on the work of each group, to be made available to the group, the WWS-OC, the GDE, and the relevant funding agency. We anticipate that these reports will be useful to the groups seeking ongoing support for their work and to refine their R&D activities. The reports will also provide input to the existing regional review processes (such as the DESY PRC in Europe), which will continue to provide important guidance. This system will cover the transition period until R&D activities become the responsibility of experiment collaborations. We should further comment that these reviews will be held in addition to, not instead of, the existing detector sessions at the regional workshops. These sessions will continue to be important channels of communication of new results, as well as enabling young physicists to present their own work. Sincerely, [GDE EC, WWS-OC chairs] **************************************************** In the discussion that followed, doubts were expressed because of the duplication of effort (WWS + regional reviews), about the proposal that open-session reports are by country and not by topic, and about the need for a review for the detector which is regimented to the level of that for the machine. There was the thought that FALC would be more appropriate than the GDE as co-sponser. There will an session at Valencia where everyone can express their opinions/critcisms about this review proposal. 2. WP Meeting --------------------------------- -2a.Preparations for the WP meeting at Valencia (slides#10,11,12) The outline of tasks for the TPC LP was put together by Ties and iterated on by Takeshi, Keisuke, RS and the Desy TPC group before today's phonemeeting. Ties distributed this 'Project List2 LP TPC.doc' which was used to write down some points on slides #10,11 which were discussed at the meeting. Based on feedback, the list has been updated and is available on the website as 'Project_List3_LP_TPC.doc'. Several tasks are highly correlated between various topics, and this has been taken into account. Everyone is asked to study the list so that we can converge on as many questions as possible at Valencia. Below, between the $$$ lines is the outline in text format (it is long) for completeness; the Project_List3_LP_TPC.doc file is easier to read. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Project List LP TPC Ties Behnke--Original Version 1.0 23.10.2006 After phonemeeting 25.10.2006--Version 3.0 below Symbols: --WIP (work in progress) =>things to be discussed and/or decided at Valencia 0.
