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 Super. KEKB 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 16 -17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) WBS 1. 5 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 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

• Key drivers/constraints Schedule – Deliver PIN diodes, two prototype TPCs, mechanical structure, DAQ to support Super. KEKB accelerator turn-on in Jan 2015 (phase I) – Deliver 8 final TPCs for 2 nd Super. KEKB turn-on in Feb 2016 (phase II) – Demonstration of TPC prototypes before construction of 8 final TPCs – Availability of DOE FY 14 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 CD 1 - 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

Latest Belle II / Super. KEKB Schedule • Two commissioning phases Key dates: Phase I (No QCS, No Belle Detector): Jan 2015 Phase II (QCS, Belle, no VXD): Feb 2016 Phase III (QCS, Belle, VXD): October 2016 (This plan has changed repeatedly. Our mandate is to be ready for any commissioning scenario. ) 16 -17 January 2013 Sven Vahsen, Belle II Directors Review (Pre CD-2/3) 14
