| Summary: | The development of a high sensitivity ac susceptometer is outlined in this thesis. The
intended use of this device is for the measurement of the magnetic field dependent penetration
depth of high temperature superconductors in the Meissner state. The nature of
the field depence may be useful in discerning the superconducting pairing state in these
materials.
Test measurements on the completed ac susceptometer show that its field dependent
background is too large to extract any meaningful results from this experiment. However,
the device has been used successfully to measure the temperature dependent penetration
depth and the vortex melting transition of the high temperature superconductor
