Fiducialization in « statistical loop » instead of to ITP20 • It consists in : • apply an offset (coming from statistics) to the dipole central support • carry out the fiducialization : if V1-V2 extremities are outside tolerance (0.87 mm) adjust to ITP20 • Results (42 dipoles treated from week 5, 2 benches, 1.5 teams) : • achieved 12 dipoles/week, one of them corrected to ITP20, one of them adjusted to ITP20 • out of 42 dipoles only 2 (5%) needed correction to ITP20 due to V1-V2 extremities out of tolerance • What we will try to do (with 3 benches, 2 teams) • 15 dipoles/week, 11 from cold tests, 3.5 adjusted to ITP20, 0.5 corrected to ITP20 • Impact on LHC activities • no more dipoles stored without fiducialization • all dipoles will go in the tunnel with full fiducialization • backlog of about 120 dipoles to adjust to ITP20 will be treated by end of 2005
