ACR Intensities in Interplanetary Space

Posted August 31, 2007

From: Berndt Klecker, MPE

These interplanetary particle intensities and plots are from the HILT instrument on SAMPEX. HILT was launched with a ~1000 day supply of isobutane for the proportional counter. Thus, these data cover from 20 August 1992 through 7 July 1995.

• Polar Cap Averages
  Polar cap intensities of He, O, N, and Ne in several energy ranges between 4 and 28 MeV/nuc, averaged over 1 day with the provision that the spacecraft is at magnetic latitudes of 70 degrees or higher. These data are NOT selected for quiet times. The energy ranges are provided in the following table:

  Element	Energy Range (MeV/nuc)
  Helium	4-6, 6-8
  Oxygen	8.2-16, 16-28
  Nitrogen	7.6-16
  Neon	9.2-28

  Note: Date stamps in plots are in DD/MM/YYYY format.
