Production and installation sequence

Material procurement flow PANELS

Material Specifications

Preproduction organization Prepare material for the startup of CERN, PNPI, LNF, Ferrara (5% of production) and ensure a safe margin before large tenders are completed (hopefully by beginning ’04) This plan already financed by INFN in 2003

By the end of April - mid May sending out orders for Fr4 panels and cathode pads HV bars Lateral and closing bars Gas connectors Panel preparation (300 pieces) R & C Consumable material (glue, pins, etc...) (100 km of wire already in hand) In June we should start panel preparation

“Back of the envelope” costs numerology Total cost of the material for MPWC (as of today) : 2.2 MSF No. of chambers : 1400 (approx, incl some spare) Cost per chamber = 1.57 ksf Active area covered 470 m2 (x 4 wire layers) Cost per m2 = 4.7 ksf

Conclusions The production plan is at a good level of understanding and will be validated by the experience to be acquired with the startup (>> yield) We acknowledge the tightness of the plan, although we would like to stick to it as much as possible as the contingency of the production is very little A potential problem is represented by the long time needed for material procurement both for the complicated financial environment of the LHCb Muon System (after Brasil default) and the bureaucracy of tenders A green light on an item today means having it not earlier than six-to- eight months. This is a difficult problem for procurement and we are thinking how to circumvent it
