High-sensitive magnetometers to be installed on space vehicles have been developed under a scrupulous schedule. The first program on mamufacturing of a two-core type magnetometer with a 50-cm length sensor and the second program on a comparative test of twelve kinds of ring-core sensors were already executed successfully. On the basis of the successful geomagnetic routine observation by the plot-type ring-core magnetometer mamufactured as the second program, a new ring-core type magnetometer was ordered to Sokkisha Co. as the third program with which the present report concerns. This magnetometer is characterized by a digital electronic circuit to avoid a phase mismatching due to a temperature effect on both exciting and output waveforms. It is also characterized by an automatic cancelling of parametric DC magnetic fields so as to facilitate high-sensitive recording. The output signals are registered on a magnetic tape with a transport speed of 1.524 mm/s. The signals are also registered on monitoring pen-recorders with two ways; vertical recording with 60 mm/h and with 0.3 nT/mm, and lateral recording with 250 mm/h and with 0.1 nT/mm on a routine base. The sensitivity can be changed up to 0.036 nT/mm for the vertical-writing recorder. The sensitivity is so strikingly high that even the Pc3 pulsation was registered with the maximum range of more than 170 mm at about 01h23mUT on August 25, 1979. The merits of this magnetometer are compared with those of other types of magnetometers. Possible applications of the ring-core type magnetometers to various research fields are described. |
