Abstract
An x-ray source includes an x-ray transmissive window having an x-ray transmittance greater than or equal to 20% for at least some x-rays having an x-ray energy less than 1 keV. The x-ray source further includes an electron source configured to generate at least one electron beam and an anode assembly configured to generate x-rays in response to electron bombardment by at least some of the electrons of the at least one electron beam from the electron source. The x-ray source further includes at least one x-ray optic is configured to receive at least some of the x-rays from the anode assembly and to direct at least some of the received x-rays to the window to form an x-ray beam.
