28
November 9, 2004 B Physics at a Super B Factory 28 Monolithic Active Pixels Option for very high luminosity is MAPS = Monolithic Active Pixels = sensor and electronics on the same substrate. o R&D on monolithic pixels has started in several places. Possible approaches: o Integrate electronics on the high resistivity substrate usually employed for sensors Active components are not of the best quality The fabrication process is highly non-standard with large feature size (>1-2mm) o Use the low resistivity substrate of standard CMOS process as sensor Can use standard sub-micron process with state-of-the-art electronics Far from a proven technology: fundamental R&D required

33
November 9, 2004 B Physics at a Super B Factory 33 Radiation-hard calorimeter options Lutetium (+Yttrium) OxyOrthosilicate [LSO or LYSO] o Fast light output in 40ns; solves occupancy problem. o Smaller radiation length 1.15cm (CsI 1.86cm) and Moliere radius 2.3 cm (CsI 3.8cm) o Believed to be radiation hard to 100MRad! o Currently cost is ~$40/cc; pushes radius towards 700mm Liquid Xenon o Fast light output again, within ~20ns. o Radiation length is 2.9cm: need all of radial space between 700 and 1350mm for cryostat, liquid Xenon and readout. o Moliere radius 5.7cm: long. sampling to separate overlaps. o Cost of Liquid Xenon is $2.5/cc Both Rad Hard crystal and Liquid Xenon options require EMC inner radius reduction to about 70cm: need to replace DRC bars as well
34
November 9, 2004 B Physics at a Super B Factory 34 Muon/K L upgrades Forward endcap RPCs will not survive 2x10 35 o Outer layers see large LER background (part of which will be shielded after summer 2004) o Inner layers see large Lumi background at small radii Plan already in the works to replace forward endcap with LSTs (in avalanche mode) Barrel LSTs installed in summer 2004 and again summer 2005 should be ok for all scenarios Not clear if there is interest in replacing backward endcap RPCs due to limited acceptance loss

November 9, 2004 B Physics at a Super B Factory 37 Important factors in upgrade direction Project is “tunable” o Can react to physics developments o Can react to changing geopolitical situation Project anti-commutes with linear collider Will emerge from BABAR and Belle, but could be attractive to wider community in context of other opportunities o As we learn more about machine and detector requirements and design, can fine tune goals and plans within this framework Project has headroom o Major upgrades to detector and machine, but none contingent upon completing fundamental R&D o Headroom for detector up to 5 x 10 35 ; with thin pixels beyond o Headroom for machine up to 8.5 x 10 35 ; requires additional rf, which can be staged into machine over time
