The theoretical model of large-scale ray structure formation proposed in a preceding paper (Verkhoglyadova et al., 1993) resides in filamentation instability development due to the solar wind flow partially penetrating into the cometary plasma tail. In order to study a real form of the filaments and instability development in space a study of the proposed mechanism in three dimensions is made. Cometary plasma ions and those of the solar wind seem to be collisionless, otherwise collisions of electrons dealing with scattering on ion-acoustic oscillations are characterized by effective collision frequency. The cometray plasma filaments, which are observed as bright rays, are formed due to instability development and take the form of cylindrical plasma fibers with the thickness determined by cometary plasma parameters and those of the solar wind. Under some assumptions we obtain the characteristic length which may be thought of as the maximum ray size. We evaluate the number of rays within one lobe of cometary plasma tail which varies at a range of 2-30 rays. The observational evolution of the ray structure is discussed.
