Abstract
An electrostatic probe for measurements in a magnetized plasma is proposed. It consists of a cylindrical rod with insulating end plugs, and is operate d by obtaining the current-voltage characteristic and its first derivative for different orientations of the rod with respect to the magnetic field. T he probe provides a simple estimate of ion temperature and ion density and an improved measurement of the electron energy distribution function. (C) 1 999 American Institute of Physics.
