Design and Construction of a Medium-energy Free-air Ionization Chamber

Graduate Investigator: Emily King

Summary of Research: Free air ionization chambers (FACs) can be used for the direct measurement of the ionizing ability of x-rays in air without calibration in a known field first. This quantity, exposure, is useful for characterizing x-ray sources and calibration purposes. The UWMRRC is interested in building a FAC for the medium x-ray energy range which requires a larger volume, and other extra considerations, than a low-energy FAC. The goal of this project is to design, construct and test a medium-energy FAC.
