G.Martellotti, C.Matteuzzi, CSN1 Roma 6/4/ There will be two presentations: T. Nakada (Spokesman): Stato LHCb A.Smith (Resource Coordinator): M&O cat A, CORE e CF (consuntivi 2003 e preventivi ) Overview on the LHCb RRB del 28 Aprile 2004

G.Martellotti, C.Matteuzzi, CSN1 Roma 6/4/ News of the Collaboration CB has approved in february 2004 a new collaborator: LPNHE of Paris VI and VII (software and analysis activities) within the unchanged France budget

G.Martellotti, C.Matteuzzi, CSN1 Roma 6/4/ Summary on Detector Construction Magnet assembly progressing, should be finished in June ’04; VELO: sensor and hybrid orders delayed, but still manageble, electronics: BEETLE 1.3 getting on critical path (also for ST), vacuum vessel proceeding; ST: mechanic design progressing, IT sensor order in process; OT: module production coming up with delays, electronics and support design progressing okay; RICH: RICH2 mechanics on track, RICH1, electronics and HPDs progressing, but schedule getting tight; Calorimeters: on track, installation to start in October Muon system: chamber production coming up with significant delays, electronics very tight schedule, filter construction to start in May Infrastructure installation proceeding.

G.Martellotti, C.Matteuzzi, CSN1 Roma 6/4/ Muon System: MWPC production After Production Readiness Reviews the production is now running at following sites:  CERN: planned rate 1 chamber /week, rate reached, but gain uniformity measurement missing  LNF: planned rate 2.5 chambers /week; rate shown to be reachable, not yet maintained  PNPI-1: planned rate 5 chambers /week, in training phase Three more production sites to come:  Ferrara: production just started planned rate is 2.5 chambers /week, PRR planned for April  Florence: clean room with tooling installation ready, PRR planned for May  PNPI-2: after finishing CMS production area to be converted, start-up planned for autumn this year. We will only know the actual production rate for 5 centres by summer 2004, the chamber construction and installation plan will be revised this summer, once the production rates are established.
