AN ANALYSIS OF THE BEHAVIOR OF A MULTI-GRID SPHERICAL SENSOR IN A DRIFTING MAXWELLIAN PLASMA

Abstract

A theoretical derivation of the characteristic of a spherical probe in a flowing Maxwellian plasma is given together with various limiting forms of the equations. The limitations imposed on the validity of the theory by the characteristics of the sheath are discussed. The theory is then extended to the case of an n-grid sensor. Finally, the application of the theory to the determination of plasma parameters from the probe characteristic is discussed. (Author)
