AB  - Plasma and particle observations on Ulysses during its passes through the southern and northern heliosphere have revealed that, inside the streamer belt, the large-scale structure of the quiet global heliosphere is dominated by corotating interaction regions (CIRs). Therefore, considerable attention is now being given to the internal plasma structure of CIRs, and in particular, to the mainfestations of the stream interfaces that should mark their origins as interactions between low speed solar wind (in the low-latitude streamer belt) and high speed solar wind (from the equatorial extensions of the high latitude polar coronal holes). The SWICS and HI-SCALE experiments on Ulysses combine plasma and energetic particle measurements that are of considerable utility for such studies because, between them, they cover the proton energy range from 10 eV to 5 MeV. We use these measurements, together with magnetic field data, to study the remarkable series of CIRs that occurred during the period beginning July 1992 and the end of 1993 as Ulysses rose from the ecliptic to a southern heliographic latitude of 48 degrees. We make use of the identification of interfaces recently published by Wimmer-Schweingruber et al., 1997. The structure of the regions between the forward and reverse shocks has previously been analyzed in terms of the proton specific entropy argument log (n/T3/2) that should exhibit a discontinuous jump at the stream interface. It has been claimed that the stream interface, defined with respect to specific entropy, is also associated with a discontinuity in energetic proton intensities. This paper examines the energetic particle data (> 60 keV) and how they were ordered with respect to interfaces and with respect to the magnetic field.
