  Title: SPATIAL BRIGHTNESS FLUCTUATION OF THE GALACTIC RIDGE EMISSION                   


Abstract:
 We propose to carry out a deep-pointing observation of the Galactic Plane, (l,b) =
 (28,0). The aim of this observation is to estimate the spatial brightness
 fluctuation of the galactic ridge X-ray emission (namely, GRXE). What is the origin
 of the GRXE? Is that of truly diffuse origin? or of discrete origin? Here, we want
 to reject the possibility that the GRXE is simply gathering of faint X-ray point
 sources. Judging from the results of past observations, the fluctuation of the GRXE
 seemed to be so small that interpretation of the GRXE as faint sources may be
 difficult. But statistics of the data was so poor. By this deep observation, we will
 surely come to a conclusion that the GRXE is the emission from truly diffuse galactic plasmas.
