Abstract:

The development of a rocket-borne Langmuir probe system for ionospheric research is described. Particular emphasis is placed on D- and E-region electron temperature and density measurement techniques. Present theory is discussed and found to be unsatisfactory for the rocket probe in the collision dominated D region. The development of the electronic instrumentation is cataloged and the results from a number of rocket flights are analyzed. The probe system that is recommended consists of a function generator that biases the electrode alternately between the electron acceleration region and the positive ion acceleration region and a high input impedance logarithmic amplifier capable of compressing five decades of data in the 0 to 5-volt output range. Currents can be monitored over the ambient temperature range of -10C to 50C. Author
