Project Overview James Fast Pacific Northwest National Laboratory
Why we are here • From O 413. 3 b: “Complete and review the Final Design or determine that the design is sufficiently mature to start procurement or construction. The FPD will ensure a constructability review is completed as part of the Final Design. ” 13 -December-2013 James Fast, US Belle II Technical Design Review 2
KEK Upgrade for Belle II New IR e- 2. 6 A KM mechanism does not explain cosmic asymmetry • e+ 3. 6 A Falls short by 10 orders of magnitude Primary purpose of upgraded facility Belle II/Super. KEKB Observe violations to the Standard Model and elucidate mechanisms to explain the matter/anti-matter asymmetry observed in the universe 40 x luminosity of KEKB • Positron source Damping ring New positron target / capture section Low emittance gun 13 -December-2013 Produce 100 Billion b-quarks 65 x luminosity of SLAC B-factory Japanese funding is $400 M and expect foreign contribution to detector of $23 M James Fast, US Belle II Technical Design Review 3

US Belle II Program • This is a Technical Design review of (part of) the US Belle II Project – one element of a US Belle II Program • US Belle II Program is supported by DOE & NSF programmatic grants, US-Japan Funds and the DOE US Belle II Project – Programmatic funding for US Belle II • Supports scientists working on US Belle II – US-Japan (Nichibei) funding in JFY 11, 12 ($1. 8 M total) • Enabled procurements to keep US effort on KEK schedule – US Belle II Project • Contribute detector systems for Belle II • Integrated management of US Belle II Program – Grants, US-J, Project 13 -December-2013 James Fast, US Belle II Technical Design Review 5
US Belle II Project • US Belle II project will contribute to a suite of detector systems • WBS 1. 2 imaging Time of Propagation (i. TOP) – Cherenkov radiation in quartz optics – Particle identification system to distinguish p and K • WBS 1. 3 Readout Systems – ASICs, circuit boards, firmware, DSP/FPGA code – Common electronics for i. TOP and KLM systems • WBS 1. 4 KLM Detector – Instrument flux return with scintillator and fiber – Particle identification system to identify KL and m • WBS 1. 5 Commissioning Detector – Monitor particle rates during accelerator commissioning prior to the installation of the Belle II inner detectors 13 -December-2013 James Fast, US Belle II Technical Design Review US Belle II Project 1. 1 Project Integration and Support (PNNL) 1. 2 i.

Commissioning Detector • Commissioning detector will characterize radiation near Super. KEKB interaction point during beam commissioning. • Sub-systems supplied by a number of Belle II institutes, mounted on common mechanical support structure. KEKB commissioning detector in 1998 – effort led by U. Hawaii
Arrays of 64 PIN diodes to monitor both unshielded radiation levels, and dose going into calorimeter (Wayne State University) 8 micro-TPCs for monitoring fast neutrons. (Hawaii)
Charge to the Committee • Technical Design Review of i. TOP already held last week in Tokyo – Reviewed WBS 1. 02 (i. TOP quartz), i. TOP readout portion of WBS 1. 03 as well as i. TOP integration – WBS 1. 04 (KLM modules) already received CD-3 A and are completed • This review covers the remaining portion of WBS 1. 03 (KLM readout system) and WBS 1. 05 (commissioning detector). • The review committee is asked to address the following: – – – The quality of the design. Have the operational and functional objectives been met? Is the design biddable, constructible, and cost-effective? Interface compatibility. Has a detailed, unbiased, analytical approach been used for all of the above items? I would appreciate receiving your committee's report within 30 days of the review's conclusion. 13 -December-2013 James Fast, US Belle II Technical Design Review 11
