Abstract :
A new energy-spread monitor is under development in order to control the transverse positions and energy spread of a single-bunch positron beam with charges of 4 nC. This monitor will be installed at a dispersion section of the beam transport line (E = 1.1 GeV) for the positron beam transporting from the linac to a damping ring towards the Super KEK B-factory. The author proposes the use of this new monitor consisting of multi-stripline electrodes in order to simultaneously measure not only the transverse beam positions but also the energy spread pulse-by-pulse. This report describes in detail the basic design of the energy-spread monitor, its detection sensitivity and characteristics depending on the transverse positions and energy spread of the positron beam based on numerical simulations.
