  1. Dubna modules assemblystatus (March 31 2014) • Status of: • CH2 M2 X-Y • CH4 M1 U-V • CH4 M1 X-Y • Shipment to CERN: • CH2 M2 X-Y+CH4 M1 U-V • Presented by S.Movchan 9-Oct-14 S.Movchan Straw manufacturing and QC 1

  2. CH2 M2 X-Ystatus 9-Oct-14 S.Movchan Straw manufacturing and QC 2

  3. 3 support tubes per each corner Central support tube Vacuum set up 9-Oct-14 S.Movchan Straw manufacturing and QC 3

  4. CH2 M2 X-Y frame leak to vacuum (July 2013) Leak estimation for final time interval dT=(4200-5600) min: dP=7.8-7.5 = 0.3 mBar dT= 5600 – 4200 = 1400 min Volume V=2.2x10**6 cm3 Leak: L = dP*V/dT = 0.3 mBar/1 * 2.2x10**6 cm3/1400 min ~ 0.5 cm3/min 9-Oct-14 S.Movchan Straw manufacturing and QC 4
