How does the plasmasphere affect the electron population in the outer belt?

Answer

It can block the acceleration of electrons

The plasmasphere consists of cold, dense plasma found near Earth. It acts as a regulator for the electron population in the outer belt. When the plasmasphere expands, it physically restricts the acceleration of electrons. Conversely, when it is compressed during solar storms, it allows for increased energetic activity, which can lead to dangerous electron events for orbiting spacecraft.
