We have examined features in the structure of the heliosheath using the finescale time variations of termination shock particles (TSP) between ~0.5 - 20MeV and electrons between 2.5-14 MeV measured by the CRS instrument as the V2spacecraft crossed the heliospheric termination shock in 2007. The verydisturbed heliosheath at V2 is particularly noteworthy for strong periodicintensity variations of the TSP just after V2 crossed the termination shock(2007.66) reaching a maximum between 2007.75 and 2008.0. A series of 42/21 dayperiodicities was observed at V2 along with spectral changes of low energy TSPand the acceleration of 6-14 MeV electrons. Evidence is presented for theacceleration of TSP and electrons at the times of the 42/21 day periodicitiesjust after V2 crossed the HTS. Spectra for TSP between 2-20 MeV and electronsbetween 2.5-14 MeV are derived for three time periods including the time of theHTS crossing. The energy spectra of TSP and electrons at these times ofintensity peaks are very similar above ~3 MeV, with exponents of a power lawspectrum between -3.0 and -3.6. The ratio of TSP intensities to electronintensities at the same energy is ~500. The electron intensity peaks and minimaare generally out of phase with those of nuclei by ~1/2 of a 42 day cycle.These charge dependent intensity differences and the large periodic intensitychanges could provide new clues as to a possible acceleration mechanism.

Large periodic time variations of termination shock particles between  ~0.5-20 mev and 6-14 mev electrons measured by the crs experiment on Voyager  2 as it crossed into the heliosheath in 2007: An example of freshly  accelerated cosmic rays?
