  1. Dubna straws and assembly site status (28/09/2012) • Dubna straws • - stored • - manufactured • Assembly site: • - module vacuum testresults • - straw installation tooling test • - straw position scanner status • Plans • Presented by S.Movchan 25-Oct-14 S.Movchan Straw manufacturing and QC 1

  2. Dubna straws Last straw serial number - #2784 For Dubna Module: 418 straws – stored 653straws – manufactured Total: 1071 straws For CERN Module: 506 straws will be delivered to CERN - end of October 25-Oct-14 S.Movchan Straw manufacturing and QC 2

  3. Module vacuum test at Dubna 25-Oct-14 S.Movchan Straw manufacturing and QC 3

  4. Set up for Module vacuum test Sensors r/o Pumps Table He leak detector Table gas leak is about 0.1 mbar/10h (V~0.8 m3, T=23 degree) Leak L = 170 mbar*cm3/min 25-Oct-14 S.Movchan Straw manufacturing and QC 4

  5. Module deformations control Common view 6 micrometers: 4 –> on side + 2 –> on top Elastic deformations are about (60+/-20) μm 25-Oct-14 S.Movchan Straw manufacturing and QC 5

  6. Leak dP=0.7 mbar dT=2964 min V=2200000 cm3 dP/dt=2.36*10-4 mbar/min Leak ~ 520 mbar*cm3/min (video film is available) 25-Oct-14 S.Movchan Straw manufacturing and QC 6

  15. Plans • October 2012 • Installation and tuning of straw supports - 1 week • Tooling for straw gluing check • Laser scanner preparation • Technology verification: • Step 1 (without gluing): - 1 week • - installation of 14 straws (will be used 1/2 set of tooling) • - measurement position of 14 straws by laser scanner • Step 2: - 1 week • - gluing of 14 straws • - measurement position of 14 straws • November 2012 - 4 weeks • Start straw mass-gluing • December 2012 - 4 weeks • Continue straw gluing 25-Oct-14 S.Movchan Straw manufacturing and QC 15

  16. Conclusion Straws: Straw manufacture rate– 100 straws per week Dubna Module: stored - 418 straws manufactured - 653 straws Delivery 506 straws to CERN – end of October 2012 Dubna assembly site: Module vacuum test: leak L ~ 500 mbar*cm3/min Technology verification - October 2012 Start straw mass-gluing – November 2012 25-Oct-14 S.Movchan Straw manufacturing and QC 16
