Super B Factory Workshop
19 January 2004
Improvement in luminosity with
different tunes (~KEKB)
Beam Optical Parameters of SuperKEKB:
LER dynamic aperture
Red: injected beam
Total number of RF units at KEKB and SuperKEKB.
One unit = one klystron + 1 SCC or 1(2) ARES at SuperKEKB (KEKB)
T0 = revolution period (10 usec)
k = loss factor
I = beam current
nb = number of bunches
Pulse beam kicker installed
before positron target for
quick switching between
beams (50 Hz).
Prototype C-band structure
installed and tested at linac
using actual beam (2003).
Measured field gradient of
41 MV at 43 MW agrees with
RF: Use KEKB ARES cavity (509 MHz)
FODO cell w/alternating bends
Green = injected beam, red = 4000 turns max deviation
(thick = ideal machine, thin = machine errors included)
Evolution of luminosity and beam size in
weak-strong (PIC) and exact solution
