To groups active in - or planning - detector R&D for the ILC INVITATION FOR INPUT TO THE DETECTOR R&D PANEL OF THE WWS --------------------------------------------------------- (WWS = the Worldwide Study of Physics and Detectors at the ILC) At LCWS in Stanford at the end of March the WWS organising committee established a panel to promote and co-ordinate detector R&D for the ILC. Its chair is Chris Damerell (other members listed below*). Before the Snowmass workshop in August the panel wishes to get a complete picture of all the R&D projects now happening around the world. They will maintain the picture on a webpage so that new groups can see what is already being done. They will also be in touch with the three teams who are developing whole-detector concepts for the ILC (SiD, "LDC" and "GLD" - see e.g. talks at LCWS on Monday 21 March at 16.30, on http://www-conf.slac.stanford.edu/lcws05/program.htm). On the Snowmass timescale we need to know which R&D topics that are urgently needed for the detectors are covered by funded programmes and which topics are missing. Could you please, therefore, confer with colleagues in your own R&D project and choose a contactperson who will send a message to Chris <[log in to unmask]>. He, or another panel member, will get in touch with your contactperson and explain how to get your project publicised through the new international website. The list of topics being considered by the Detector R&D Panel comprises: Measurement of luminosity, beam energy and polarisation; Vertexing; Tracking; Calorimetry (ECAL, HCAL, forward region) Muon tracking Particle ID DAQ systems Electromagnetic interference Further detector R&D topics can be suggested.
