Production responsibilities
Production Responsibilities

  • HedgeHogs (common production by CERN)

    • HV - INFN (all types)

    • Signal - Boston (EndCaps), Chamber-Builders (Barrel)

  • ASD - Boston U and Harvard

  • AMT-TDC - KEK

  • Mezzanine Boards - Harvard and Boston U

  • Chamber Service Module -To Be Determined!

  • ROD - (Freiburg, Munich LMU, Munich MPI) 20%, Nijmegen 41%, Saclay 33%, JINR 6%

Core cost estimate
“Core” Cost Estimate

  • HedgeHogs (32,000 HV+signal): 1,892 kCHF

    • (assumes common CERN production)

  • AMT-TDC (16,000): 1,330 kCHF

  • Mezz Boards (16,000): 2,433 kCHF

    • (includes 45K ASD chips)

  • Patch Panels 382 kCHF

    • (replaced by Mezz -> CSM cable assemblies)

  • Off Chamber Electronics 1,682 kCHF

    • (does NOT include CSM)

  • George Brandenburg – Page 4


    Cost estimate issues
    Cost Estimate Issues

    • HedgeHogs: Common production at CERN of all types now being planned to reduce costs.

    • ASD: Current HP quote is $375K ≈ 600 kCHF, but production must be finished before HP phases out process.

    • Mezz Boards: Quote for US production is $1,875K ≈ 3,000 kCHF –> CERN prod. is being investigated.

    • Patch Panels: No longer needed, but individual Mezz -> CSM cables (16,000) may cost more.

    • CSM: estimate for 1,320 modules is $1,221K ≈ 1,950 kCHF, however, funding source NOT yet determined!
