Twelve years of SR monitor development at the KEK

Abstract
The synchrotron radiation (SR) monitor based on visible optics is one
of the most fundamental diagnostic tools in the high energy circular accelerator.
The monitor gives a visible beam profile, beam size, longitudinal profile,
etc. These greatly improve the efficiency of commissioning and operation
of the accelerator. We have worked on the development of SR monitors over
the past twelve years at KEK. During these years, the development of the
SR interferometer has been the most significant topic. The idea of
the SR interferometer for measurement of beam profile and size struck me
while I was performing experiments to investigate the coherence of synchrotron
radiation in 1994. After basic investigation of beam profile and
size measurements with the SR interferometer, this apparatus was applied
to daily monitoring of beam size. Nowadays, the SR interferometer
is recognized as a powerful tool for easily measuring small beam sizes.
I review the development of the SR interferometer. History, theoretical
background, some experimental results and practical notes on using the
SR interferometer are
described.
