Abstract : A description is given of the construction and operation of an X - band microwave system for measurement of the dielectric constant of ferroelectric materials, and also the construction of a broad band, coaxial sample holder. Preliminary measurements of the dielectric constant of potassium dihydrogen phosphate (KDP) at approximately 9.4 Ghz show this to be above the dielectric relaxation frequency of this solid. Extensive measurements made to detect the coupled proton tunneling - soft mode in KDP show that the mode does not reach this low a frequency, which is attributed to the slight first order nature of the transition.
