  • HFT PIXEL ProgressFace to Face13 May-2009Wieman*

  • Sector structures*

  • ladder fabrication and tooling*

  • ladder fabrication and tooling*

  • ladder fabrication and tooling*finalizing mechanical designs and developing rapid production methods

  • ladder fabrication and tooling*ladder withsilicon heaterchips(50 m thick)

  • wire bonding 50 m silicon to flex PC*vacuum chuck tosecure flex and siliconflat against solid surfaceto remove bounce

    Any bounce then no bondGood Newsafter a couple of minor modifications to the vacuum chuck thewire bonding machine is happyRhonda is happy

  • ladder to sector tooling fixtures (4 stations)*

  • Air cooling of silicon detectors Computational Fluid Dynamics (CFD) analysisair flow path flows along both inside and outside surface of the sectorSilicon power: 100 mW/cm2 (~ power of sunlight)240 W total Si + drivers

  • Full sized cooling testsThermal camera window not shown> 300 CFPM air flow for verification of cooling capabilityCooling tests will begin as soon as prototype sectors completed9 inch diameter tube mocks upISC*dust collector for air supply
