| Zusammenfassung |
| The Cluster/CODIF sensor is a time-of-flight instrument that measures the
ion composition over the energy range 40 eV e−1 to 40 keV e−1. It
operated for 4 yr on S/C 1, 9 yr on S/C 3, and is still operational on
S/C 4, after more than 12 yr. During this time the total ion detection
efficiency has decreased by a factor of 50. In this paper, we describe the
methods used to track the efficiency changes throughout the mission for the
three different spacecraft and for the different ion species. The methods
include calculations of the efficiencies using rate data collected in the
instrument, comparisons with other instruments on the Cluster satellites,
and checks based on geophysically reasonable assumptions. |
