Accl. Field 21 -> 41 MV/m e+ Damping Ring for lower emittance Achieved 40 MW (0.5ms, 50pps), > 40 MV/m (1m structure) Goal: 40 MW 40 MV/m Octl 9th, 2003Nobu Katayama39 Summary Belle and KEKB have achieved 1.0610 34 cm 2 s 1 and 158 fb 1 We have installed SVD2, two more RF cavities and come back online in 2 wks We are hoping to upgrade KEKB and Belle to reach luminosity and to accumulate 3000fb 1 before 2010 when LHC starts producing results Simulation tells us that we may reach 5 with head-on collision with crossing angles using the crab cavities
