When measuring the transition temperature of large numbers of high Tc superconducting samples it is desirable to have available equipment that is both easy to operate and reliable. In addition should anything malfunction, the device should be relatively simple to repair. One method of measurement involves placing a sample in the magnetic field of an inductor, the inductor being an active member of some type of oscillating circuit. There are many standard oscillator designs which can be used for this type of application. In this report two such circuits, the tunnel diode and Hartley oscillators, will be examined and evaluated on their potential as measurement devices for superconductor transition temperatures.
