We examine events where the TIDE and TIMAS ion instruments on board the Pol
ar spacecraft have observed transversely accelerated ions (TAI) at altitude
s greater than 20,000 km. We report both H+ and O+ populations that have be
en heated perpendicular to the local B field but that also have a sharp low
-energy cutoff to the distribution occurring at 20 - 100 eV. Analysis of an
event on 21 April 1996 indicates that the formation of ion toroids may be
related to solitary structures or low frequency wave pulses observed during
the event. We address some of the implications of using time (as opposed t
o frequency) domain techniques to analyze wave/particle energization events
