Zusammenfassung |
The Plasma Electron and Current Experiment (PEACE) instruments operate on all
four of the Cluster spacecraft and measure the 3-D velocity distribution of
electrons in the energy range from 0.59 eV to 26.4 keV during each
spacecraft spin. Pitch angle distributions and moments of the velocity
distribution are also produced. As the mission has progressed, the efficiency
of the detectors has declined. Several factors may play a role in this
decline such as exposure to radiation, high electron fluxes and spacecraft
thruster firings. To account for these variations, continuous in-flight
calibration work is essential. The purpose of this paper is to describe the
PEACE calibration parameters, focussing in particular on those that vary over
time, and to describe the methods which are used to determine their
evolution. |
