Dear Colleague, There will be an International Workshop on Linear Colliders at Jeju island, Korea, from August 26 to 30, 2002. We are now organizing the sessions H for calorimetry, muon, and other detectors, and would like to invite you to submit your contribution to this session. The topics in this session include: 1) Calorimetry (barrel, endcap, forward, very-forward,...), 2) Muon Detectors, 3) Dedicated Particle-Identifier, 4) Luminosity Detector (Spectrometer), (Instantaneous luminosity monitor for beam handling will be covered in session K) 5) Instrumented Mask, Forward Energy Tagger/Veto, 6) Simulation studies relevant to above detectors and all other possible detectors, while *) trackers (central, intermediate, vertex, forward,...) will be covered by session G, and *) beam diagnositcs (BPM, pair-monitors, polarimeters,...) will be covered by session K. We have already received several contributions (including un-official ones), and have made a list of expected talks as http://www.slac.stanford.edu/xorg/lcd/calorimeter/LCWS02_cal_agenda.html In addition, we are considering to organize a joint session of H and J for extensive discussion on simulation studies. You can submit your contribution via the web page http://lcws2002.korea.ac.kr/abs.mktable.php We are looking forward to having your contributions. With best regards, Paul Dauncey Ray Frey Yoshiaki Fujii Marcello Piccolo
