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.
