What is it about?
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 (${\bm E}$ = 1.1~GeV) for the positron beam transporting from the linac to a damping ring towards the Super KEK B-factory.

Why is it important?
The energy-spread monitor (ESM) is a very useful monitoring tool to cater to such requirements. The ESM will detect both the transverse beam positions and the energy spread at large dispersion sections by measuring any variations in the electromagnetic field distribution induced in the multi-stripline electrodes located in the monitor.
Perspectives
The ESM has been newly designed by numerical simulations based on the electrostatic analysis of a charged beam. It is expected that with such ESMs, the energy spread could be made as small as possible under real-time operation within a relative resolution of the order of 10$^{-4}$ along with transverse resolution of the order of less than 0.1~mm with the use of suitable detection electronics.
