In this work, solar flare energetic particle fluxes (Ee > 42 keV) observed by the ULYSSES/HI-SCALE and ACE/EPAM experiments are utilized as diagnostics of the large-scale structure and topology of the interplanetary magnetic field (IMF) embedded within well-identified magnetic clouds and non-cloud Interplanetary Coronal Mass Ejection (ICME) structures observed at high and low heliolatitudes. On the basis of the energetic particle observations firm conclusions are drawn on whether the detected ICMEs have been detached from the solar corona or are still magnetically anchored to it when they arrive at the spacecraft. The observation of solar electron event onsets within some ICMEs with energetic electrons streaming for long intervals along the magnetic field implies that open field lines rooted to the Sun at only one end are threading through these ICMEs. Based upon the time history of the angular distributions of the particle intensities we infer that parts of some ICMEs comprised both open and closed magnetic field topologies. The detection of counterstreaming electrons in certain portions of some ICMEs during solar particle events is consistent with the trapping of the injected electrons within closed magnetic structures. Moreover, our particle observations suggest that some ICMEs involve more complex intertwined structures including regions both connected to and disconnected from the Sun.
