Development and application of low power X-ray tube excitation system for energy dispersive XRF analysis
Description
The results achieved with an excitation system developed by using a low power, changeable anode X-ray tube are presented. The X-ray tube was fitted to vertical Si(Li) spectromter and supplied by an X-ray power supply developed for low power X-ray tubes. The X-ray yields and detection limits were investigated as a function of tube voltage and current in the range of atomic numbers Z = 13 to 58. The detection limits obtained with the X-ray tube are compared to ones achieved by using 55Fe, 125I, and 241Am. A new detection - excitation system was also constructed consisting of a 450 Si(Li) cryostat and a flexible measuring chamber. The details of this system are also given. (author)
