Abstract

Operating the microfocus X-ray source at high power is required to achieve high temporal resolution. Howev-er, the thermal loading of the anode focal spot is a limiting factor in determining the maximum power of an x-ray tube. In this paper, a transmission window based on polycrystalline diamond, for improved brightness in microfocus X-ray tube was demonstrated. The polycrystalline diamond films which were deposited by hot fil-ament chemical vapor deposition (HFCVD) approach revealed good intrinsic thermal properties. We devel-oped a reliable method to fabricate and estimate the windows/target assembly, quantitatively analyzed the an-ode heat load of the X-ray source operating under the electron beam irradiation, and then tested in a micro-focus X-ray tube. It's believed that the experiment and calculation results presented here can be generally ap-plied for the design and the fabrication of a high brightness microfocus X-ray tube employing polycrystalline diamond windows.
