Conclusion

Dubna NA62 straw modules assembly 3 halls (S ~ 250 m2) – readyModule assembly tooling – in manufactureVacuum pump and pressure sensors – ok!Vacuum table – will be ordered

NEXT steps will be fixed on the July collaboration meeting at CERN----------------------Other ?????Straws manufacture (no tape at Dubna)Final module drawings – NO alignment/reference holes in the existing drawingsOrder module mechanics manufacture at Italy – date and quantity, cost ?Delivery module mechanics to Dubna (by track ?)

Module glue procedure (Francisco) Device for actual straw position measurement (like at CERN or …?)Straw glue procedure finalization – August 2011 ?

Materials and components: wire, pins, glue, straws supports o-rings, bushes, WEBs, gas manifolds, cowers with front end boards, …

Equipment: epoxy dispenser (2-3 pc), crimpers, wiring machine, DAQ, LV, HV, gas rack, …
