The L10711 microfocus x-ray source manufactured by Hamamatsu Corp. delivers the resolution (0.25 µm minimum) and stability required for x-ray nondestructive inspection, 3-D imaging and computed tomography (CT). The stable operation benefits customers performing x-ray CT scans. The built-in power supply and the improved cathode materials and design produce a stable x-ray focus spot size and stable, continuous output. The cathode design also makes it easy to replace. Two types of cathodes, one for high resolution (S mode) and the other for high intensity (W mode) are available. With the high-resolution cathode, the source produces a minimum resolution of 0.25 µm and a tube voltage range of 20 to 100 kV. With the high-intensity cathode, it produces 8 W of intensity, a minimum resolution of 0.8 µm and a tube voltage range of 20 to 160 kV.
