Abstract: X-ray transparent insulation can be sandwiched between an x-ray window and a ground plate. The x-ray transparent insulation can include aluminum nitride, boron nitride, or polyetherimide. The x-ray transparent insulation can include a curved side. The x-ray transparent insulation can be transparent to x-rays and resistant to x-ray damage, and can have high thermal conductivity. An x-ray window can have high thermal conductivity, high electrical conductivity, high melting point, low cost, and matched coefficient of thermal conductivity with the anode. The x-ray window can be made of tungsten. For consistent x-ray spot size and location, a focusing plate and a filament can be attached to a cathode with an open channel of the focusing plate aligned with a longitudinal dimension of the filament. Tabs of the focusing plate bordering the open channel can be bent to align with a location of the filament.

Abstract: A multi-pixel x-ray source is provided. The x-ray source includes a plurality of transmission target assemblies. The transmission target assembly includes a tungsten target and a diamond substrate. The substrate includes a first transmission surface and a second transmission surface opposite first transmission surface. The substrate further includes a first side surface and a second side surface disposed between the first and second transmission surfaces. The target covers the first transmission surface of the substrate. The transmission target assembly further includes a base. The base surrounds the first and second side surfaces of substrate, exposing a collimator surface of the second transmission surface and the target. The transmission target assembly is configured to transmit x-ray generated by the target through the target and the substrate.
