1 NA62 SILICON PIXELS DETECTOR COOLING VESSEL PROTOTYPE STATUS REPORT COOLING VESSEL PROTOTYPE STATUS REPORT 1Vittore Carassiti - INFN FECERN, 26/10/2009

2 Vittore Carassiti - INFN FE2CERN, 26/10/2009 PARTS MATERIAL PARTMATERIAL PCBGLASS FIBER VESSEL WALLKAPTON TYPE H VESSEL FRAMEALUMINUM RESINEPOXY (ARALDITE 2012) MATERIALS

3 Vittore Carassiti - INFN FE3CERN, 26/10/2009 MATERIAL PROPERTIES MATERIALDENSITY (Kg/m^3) THERMAL CONDUCTIVITY (W/mK) CTE (K^-1) ELASTIC MODULUS (Pa) POISSON’S RATIO TENSILE STRENGTH (Pa) GLASS FIBER20760,836,7E-0645E+090,2848E+06 KAPTON TYPE H14200,1645E-062,5E+090,34230E+06 ALUMINUM ,5E-0670,6E+090,345120E+06 EPOXY (ARALDITE 2012) 11800,2230E-062,5E+090,3460E+06 MATERIALS

4 Vittore Carassiti - INFN FE4CERN, 26/10/2009 MAKING THE PARTS THE ALL PARTS MADE BY FERRARA WORKSHOP

5 Vittore Carassiti - INFN FE5CERN, 26/10/2009 ROOM TEMPERATURE THE FOLLOWING TESTS HAVE BEEN DONE :  KAPTON CREEP  KAPTON FAILURE PRESSURE KAPTON-RESIN-ALUMINUM  QUALITY OF THE JOINT KAPTON-RESIN-ALUMINUM

6 Vittore Carassiti - INFN FE6CERN, 26/10/2009 BONDING ALUMINUM FRAME & KAPTON FOIL PREPARATION OF THE JOINTS : ALUMINUM JOINT ABRADED AND DEGREASED KAPTON JOINT LIGHTLY ABRADED AND DEGREASED CURING TIME : 16 40°C

7 Vittore Carassiti - INFN FE7CERN, 26/10/2009 BONDING ALUMINUM FRAME & KAPTON FOIL

8 Vittore Carassiti - INFN FE8CERN, 26/10/2009 KAPTON CREEP TEST Working pressure Wp = 1 bar Test pressure Tp = 2Wp = 2 bar AFTER TWO Tp NO EVIDENCE OF CREEP SMALL RESIDUAL DEFORMATION AFTER VENTING

9 Vittore Carassiti - INFN FE9CERN, 26/10/2009 KAPTON FAILURE PRESSURE STRESS ON THE VESSELBOUNDARY CONDITIONS Pi = 0,1 Mpa (inner pressure) Pe = 0 (outher pressure) s = 5E-05 m (wall thickness) Di = 47E-03 m (inner diameter) EQUIVALENT TENSILE STRESS (Guest criterion) FAILURE PRESSURE CALCULATION

10 Vittore Carassiti - INFN FE10CERN, 26/10/2009 KAPTON FAILURE PRESSURE TEST FAILURE PRESSURE = 5 bar ACCORDING TO CALCULATION

11 Vittore Carassiti - INFN FE11CERN, 26/10/2009 JOINT KAPTON-RESIN-ALUMINUM LENGTH OF THE OVERLAP CALCULATION

12 Vittore Carassiti - INFN FE12CERN, 26/10/2009 JOINT KAPTON-RESIN-ALUMINUM THE JOINT AFTER KAPTON FAILURE

13 Vittore Carassiti - INFN FE13CERN, 26/10/2009 COOLING VESSEL THE COOLING 1,5 bar

14 Vittore Carassiti - INFN FE14CERN, 26/10/2009 THE POWER OF THE DETECTOR 16 RESISTORS 222 Ω – 2W 3 THERMOCOUPLES K TYPE (from -50°C to +250°C)

15 Vittore Carassiti - INFN FE15CERN, 26/10/2009 THE ASSEMBLY

16 Vittore Carassiti - INFN FE16CERN, 26/10/2009 NEXT STEP : CECKING THE COOLING IN VACUUM DN 160 CF FLANGE ELECTRICAL CONNECTIONS & POWER SUPPLY NITROGEN IN-OUT COOLING VESSEL
