Crab crossing New IR b*y = σz = 3 mm SuperKEKB Crab cavities installed and undergoing testing in beam e+ 9.4 A e- 4.1 A Studies also for low-emittance scheme has started. Dampiing ring The superconducting cavities will be upgraded to absorb more higher-order mode power up to 50 kW. The state-of-art ARES copper cavities will be upgraded with higher energy storage ratio to support higher current. Higher current More RF New vacuum system + Linac upgrade The beam pipes and all vacuum components will be replaced with higher-current design. will reach 8 × 1035 cm-2s-1
Super-Belle (Baseline) ECL Wave sampling + pure CsI crystal(endcap) PID Threshold Aerogel + TOF → TOP + Aerogel-RICH KL/m detection RPC → Scintillator +SiPM(endcap) Final design ? How do we decide, and when ? CDC Super small cell Longer lever arm New Dead time free readout and high speed computing systems SVD 4-lyr DSSD → 2-lyr. DEPFET pixel + 4-lyr DSSD
Time Line • Near-term plan (preliminary) • Detector proposals (by summer 2009). • The final detector design by Dec. 2009. 2009 2010 2008 1 2 3 4 5 6 7 8 9 10 11 12 1 2 3 10 11 12 KEKB operation Internal review Detector proposals We need make clear the Time line / Milestone (also for accelerator design) Kick-off meeting (Dec 08) TDR Actions to invite new collaborators
We must get ready before the G-Light ! • Accelerator • High current scheme or Low emittance scheme • Detector • Finalization of detector design • Organization • Collaboration name ? • Funding • Phyiscs Photodetector for E-PID Need determine the time line
