Title	Interaction between the Precipitating Electrons and the Auroral Plasma
Contributors	R Bingham (SERC Rutherford Appleton Lab.), DA Bryant (SERC Rutherford Appleton Lab.)
Abstract	The excitation of Langmuir turbulence due to the presence of a directed high energy electron stream in the aurora plasma can modify the behaviour of ion acoustic waves and lead to a modulational type instability. The effect of the turbulence on the plasma is to provide a low frequency force, the ponderomotive force, this force· interacts with the low frequency modes changing their dispersion relations. The high frequency turbulence undergoes a roodulational type instability leading to a bunching of the Langmuir turbulence in space. An effective temperature T(subscript)eff due to Langmuir turbulence can be derived.
