  1. Status of Chamber Construction QC at CIEMAT B. de la Cruz CIEMAT (Madrid) CMS Week February 2003

  2. Number of SL and Chambers produced up to now: • 54  SL • 28  SL • 24 assembled chambers, 19 already sent to CERN. Next week, shipment of 5 more chambers. Summary showing continuous trend in construction items: • Wire positions and tensions • Corner Block positions • Chamber thickness & planarity Muons DT QC Meeting - February 2003 CMS Week B. de la Cruz CIEMAT (Madrid)

  17. Public Info Public Information on chamber constructionand tests is available at http://wwwae.ciemat.es/cms/QC.html At the moment we are moving our information on DT construction into the Oracle DT Production Database at CERN, proposed by Pablo, see: http://oraweb03.cern.ch:9000/pls/cms_mb_prod/chambers.main Shortly this will beour unique reference database. Asccii files, if needed, will be automatically produced from it. Muons DT QC Meeting - February 2003 CMS Week B. de la Cruz CIEMAT (Madrid)
