A beam diagnostic system for the test is discussed in this paper. The beam position and bunch length will be measured by using a standard button-pickup BPM; while the beam emittance will be measured by using a CCD-based synchrotron light detector. Especially, accurate time measurement is essential to carry out OSC experiments with a single particle. Desired time resolution is the order of 100 ps to study the cooling decrement in various lattice parameters. SiPM is an attractive solid-state device to detect a time domain synchrotron radiation photon. It can realize a fast rise time < 100 ps with a short time width 1-2 ns FWHM and its quantum efficiency is > 40 % at 420 nm. The beam instrumentation required to tune timing in the OSC insert is also discussed. It is based on the interference of radiation coming from the pickup and kicker undulators.
