Material procurement Panels 1300 produced (over 5700 planned) – Stop of the production in August (still at 50% of FR4 sheets delivered by ELTOS) – Restarted in Sept. PNPI : M3R4-M2R4 under production LNF : production of M5R3 started CERN : waiting for M2R2-M2R1 (should be moulded together !) PZ-FE – FI : in stand-by (enough already done) – Additional material needed Problems Quality tests at the company have improved Still some problems with the new moulds – Erratic quality - may be due to thickness of FR4 sheets (0.8 mm up to 0.95 mm, marginally in acceptance) - under investigation, probably solved Feedback to Eltos given – promise not to exceed 0.9 mm Production yield 60/1300 + panels discarded in PZ/FE LNF team (Alvaro & co.) continuing to check the planarity of all panels ROME2 panel-o-meter with new measuring technique ????? P. Campana – LHCb Week – Chia – September 2004
HV bars 40% of the material delivered: M3R3-M3R4-M1R3 finished, M2R3-M2R4-M5R3 under completion the rest by the end of the year FR4 frames M2R4-M3R4-M3R3-M2R3 delivered M5R4 1/3 ordered the rest to be ordered now (waiting for offer) Faraday cages Finalizing INFN layout – to be replicated to PNPI (order next year) OPB 2100 red+1400 yellow +120 DCRO delivered (needed INFN 1300 red+950 yellow; CERN ? Which type ? In total 752) SPB needed to test chambers >> PZ <<!
