The authors have executed succesfully three times of magnetic measurements with both proton and fluxgate magnetometers installed on balloons that were launched from the Sanriku Balloon Center, Institute of Space and Aeronautical Science, University of Tokyo. The measured magnetic data were used to study magnetic anomalies in Tohoku District especially in relation to an effect of the 1978 Miyagi-Ken-Oki Earthquake of off-Miyagi Prefecture. The purpose of this paper is to report on a project of a balloon flight in September, 1979 when a newly disigned ring-core magnetometer is to be installed. This flight is planned as a fourth program of the project of developing high-sensitive satellite-borne magnetometers. This balloon-borne magnetometer consists of three-component main sensor, one-component sub-sensor and their electonics. The main- and sub-sensors are put at the bottom and the top, respectively, of an aluminum pipe with 2 m length that is hanged at 5 m below the control gondola. The sub-sensor is used to cancell an artificial bias field due to the gondola. In the electronics, frequency of the exciting current is stabilized by a crystal oscillator, and the power supply is minimized by applying C-MOS Ic's. The high-sensitivity of the magnetometer can be hold by applying the automatically cancelling method, by which the output of the magnetometer can be always restricted within ± 2.3 V for any large magnetic field by means of a comparator, reversible counter, and D/A converter. |
