This report presents improvements of investigations on the Tethered Satellite System (TSS)-1R electron current enhancement due to magnetic limited collections. New analytical expressions are obtained for the potential and temperature changes across the pre-sheath. The mathematical treatments in this work are more rigorous than one past approach. More experimental measurements collected in the ionosphere during the TSS-1R mission are adopted for validations. The relations developed in this work offer two bounding curves for these data points quite successfully; the average of these two curves is close to the curve-fitting results for the measurements; and an average of 2.95 times larger than the Parker-Murphy theory is revealed. The results indicate that including the pre-sheath analysis is important to compute the electron current enhancement due to magnetic limitations.

“…As discussed in the introduction it was the intent that the SPESs would track the spacecraft potential (possibly as high as +5000V) as the current was varied in the tether circuit by various techniques (see Dobrowolny and Stone, 1994). This would be accomplished by observing the accelerated thermal electron spectrum.…”

Abstract. Particle measurements up to 27,000 eV were made on the TSS-1R (Tethered Satellite System) satellite. The TSS satellite developed a positive bias due to the Lorentz force. It was the intent that electron measurements on the TSS satellite could be used to track the spacecraft potential and collected current. What was observed was quite different. Accelerated ionospheric electrons were observed to only ~70 eV even though larger spacecraft potentials were observed by other diagnostics on the TSS satellite. When observed they agreed with these independent measurements of the potential. In addition to the anticipated accelerated thermals, a suprathermal population of

“…Although the tether break eliminated planned observations, a "target-ofopportunity" measurement provided the first ever simultaneous, dual-point, in situ measurement of ionospheric structures using space tethers, and resulted in direct measurement of tilt and horizontal density variations in vertically correlated plasma structure. A summary of the TSS-1R mission and details of primary mission goals and hardware are given in Stone and Bonifazi [1998] and Dobrowolny and Stone [1994a].…”
