Abstract:
The REPT instrument aboard the Van Allen Probes (RBSP) mission has provided high-quality measurements of energetic and ultra-relativistic electrons and protons in the Earth’s radiation belts for over 7 years. However, the electron data below L~2.8 are affected by a background signal that is due to high energy particles, associated with the inner proton belt, penetrating the instrument. This background has proven difficult to subtract as the background varies from orbit to orbit and has an underlying intensity relationship with L-shell. This background signal has hindered quantitative studies of electron injection into this region. We will discuss recent efforts to create a correction algorithm to remove this background signal. The correction algorithm identifies trends between the proton counts and electron counts in each pass of the spacecrafts through the inner zone. The subtraction significantly reduces the background signal and can help reveal the behavior of real electrons in the inner zone.
