Summary
"A well characterized, variable plate separation ion chamber was utilized as a detector to collect x-ray attenuation data for generating information on the Laplace transform predicted spectrum of a 50 KvCP conventional x-ray tube. The variable plate separation feature allows one to include a wavelength dependent correction to the detector response which is associated with the hardening of the x-ray spectrum as it traverses the attenuating material. With this correction, the conventional two-term Laplace transform was shown to approximate independently the bremsstrahlung and characteristic L radiation from the tungsten target. The detector provides an absolute statement of the target-referenced x-ray spectrum which can be employed to specify the energy deposition in any arbitrary material system for which adequate data on the mass energy transfer coefficients are available. The aluminum attenuated derived spectrum was applied to polyethylene, and experimental and predicted data agreed to within 1% for thickness of polyethylene extending to one centimeter and exhibited a maximum average error of less than 3% for thickness up to 2.5 centimeters. The results of this study are critically compared with the literature available to-date and sources of error inherent in the published information generated with window type, fixed plate separation ion chambers are analyzed"--Abstract, p. ii
