WBS 1.05 Commissioning Detector Scope, Cost & Schedule Sven Vahsen University of Hawaii
Talk Outline WBS Element Scope Performance Requirements Cost Estimate Schedule Risk Summary 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 2
Scope I: Objectives 1. Determine if dose rate safe for Belle II roll-in and later operation at design luminosity (Belle I: hole in beampipe and damage to silicon vertex detector) 2. Provide real-time measurements of luminosity and backgrounds (needed by SuperKEKB during beam commissioning) 3. Validate Belle II beam background simulation (Distinguish different beam background sources (Touschek, Radiative Bhabha, Beam-gas, Synchrotron) 4. System tests for Belle II (Beam abort system, moveable mask positions, pixel detector cooling, inner detector occupancies) 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 3
Scope II: WBS Element Scope Lead design, simulation, DAQ integration (off-project) Construct support structure Prototype & construct PIN-diode radiation dose monitoring system Prototype & construct micro-TPC neutron monitoring system Perform acceptance tests at KEK WBS 1.5 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 4
Performance Requirements I Measurement of instantaneous and integrated radiation dose to 30% accuracy 64 PIN diodes with amplification circuits Sensitivity to synchrotron light shield half of PIN diodes with gold paint, rest unshielded Identification of fast neutrons & measurement of recoil direction (resolution 15 ) 8 micro- TPCs Rigid, non-magnetic mechanical support for all sub-detectors, with position accuracy 1 cm 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 5
Performance Requirements II Pre-prototypes of both the PIN diode system and micro-TPCs have met and exceeded all Key Performance Parameters Documented in Technical Design Report More detail to follow in technical presentation 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 6
CD-1 Cost Estimate Dollars in Thousands ($000s) Commissioning Detector Fiscal Year WBS Type of Cost 2012 $0 $0 2013 $104 $64 $6 $34 2014 $128 $95 2015 $0 $0 2016 Total $231 $159 01.05.02 - Prototyping Labor Material Subcontract $6 $66 $191 $50 $27 $115 $12 $5 $7 $435 $32 $165 $32 $27 $107 01.05.03 - Fabrication/Construction (62963 - MIE TEC) $26 $18 $0 $0 Labor Material Subcontract $8 $12 $5 $7 $38 01.05.04 - Acceptance Testing (62963 - MIE TEC) Labor Travel Total $0 $104 $293 $0 Only 3% of US project cost - but serves a critical role by protecting a large investment in Belle II 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 7
Cost Basis of Estimate Make up of cost estimate 50% of estimate associated with labor, to finalize production specifications and construct TPCs, diode system, and support structure Subcontract for TPC, diode system and support structure components and materials Maturity of the estimate Engineering estimate based on prior experience on original Belle commissioning detector, CLEO dose monitor, and prototype costs for micro-TPCs for other R&D efforts Pixel readout chip supply set aside at LBNL 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 8
Schedule Key drivers/constraints Deliver PIN diodes, two prototype TPCs, mechanical structure, DAQ to support SuperKEKB accelerator turn-on in Jan 2015 (phase I) Deliver 8 final TPCs for 2nd SuperKEKB turn-on in Feb 2016 (phase II) Demonstration of TPC prototypes before construction of 8 final TPCs Availability of DOE FY14 funds for fabrication 2011 2012 2013 2014 2015 Design & Simulation Prototyping Fabrication Acceptance Testing Schedule shows calendar years. 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 9
Major risks of WBS element 1.05 Initial elicitation completed prior to CD1 - all major risks mitigated: Reputation risk: commissioning detector fails to indicate dangerous rad environment and calorimeter is damaged Mitigation: calorimeter not present during initial commissioning include multiple silicon diodes produce comprehensive documentation for commissioning detector procedures. Technical Risk: TPCs do not adequately detect neutrons. Mitigation: testing of current prototype TPCs indicates ability to adequately detect neutrons in response to previous reviewer comments, supplemented TPCs with complementary thermal neutron detectors (He-3 tubes) (off project) 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 10
Conclusion Scope of WBS 1.5 well understood Specs validated by Technical Design Review Similar to past commissioning at Belle and CLEO Costs are known and fit within funding profile Costs defined by similar work Fits funding profile Effective management structure in place Clear reporting structure Coordination with Belle II management MOUs have been signed Project Ready for CD-2/3 16-17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 11
