20130270446 | IONIZATION WINDOW - An exemplary ionization window assembly includes a support layer having a thickness between a first side and a second side. There is at least one opening in the support layer extending between the first and second sides. The opening has a first width dimension near the first side of the support layer and a second, larger width dimension near the second side of the support layer. A window layer is supported on the second side of the support layer. The window layer extends across the opening to allow ionizing radiation to pass through the opening in a direction from the first side toward the second side. | 10-17-2013 |
20130277567 | IONIZATION DEVICE - An exemplary ionization device includes a pyroelectric electron accelerator that causes electrons to move away from the accelerator. A silicon target is positioned in a path of the electrons. X-ray radiation results from the electrons colliding with the target. | 10-24-2013 |
