| Abstract: | This paper describes balloon-borne two spheres electric field instrument formeasuring the magnitude of the vertical component of the electric field inthunderclouds. It consists of two hollow, copper spheres which are 14.3cm indiameter and helds 4cm apart. The spheres spin around an axis which is perpendicularto and at the center of the line between the centres of the spheres. The sinusoidallyvarying charge induced on the spheres by the electric field is amplified andtelemetried to ground. The amplifier and power cell are inside the two spheresseparately. This instrument is also configurated temprture, pressure and moisturesensors and can either mesure the routine meteorological factors, or the particularparameters of thunderclouds electric field. The instrument has joined in about twentysatellites safe blastoff ensure (guarantee) since 1994, and played an important role inthe safe blastoff of "australian B3 satellite" etc satellite during thunderclouds. Theinstrument can measure the magnitude of the vertical component of the electric fieldranging from IkV / m to 100kV / m with good linearity. |
