Implications of multiply-charged anomalous cosmic rays

Abstract
During the acceleration of anomalous cosmic rays (ACRs) some singly-charged ions are stripped of additional electrons. The resulting multiply-charged ions are accelerated more efficiently, and most ACRs with >=30 MeV/nuc are multiply-charged. This paper considers some implications of multiply-charged ACRs, including limits that they place on the time scales for ACR acceleration and transport, and their use in defining the cutoff in the accelerated ACR spectrum. Possible causes of the spectral cutoff in three ACR acceleration models are discussed.
