An X-ray based inspection systems providing radiographic imaging for cargo inspection and material discrimination with adaptive control dependent upon characteristics of the cargo under inspection. A packet of X-ray pulses with controllable packet duration is produced that allows multi-energy material discrimination in a single scan line and real-time adjustment of packet duration to adapt to cargo attenuation. In addition, adaptive dynamic adjustment of the operational characteristic of the detector channels increases the effective dynamic range and as a result increases the penetration and range of thicknesses where material discrimination is possible. The material discrimination technique is applied within a single packet of short pulses of several hundred nanoseconds. Feedback from the detection system is used to control the packet duration of each packet of X-ray pulses in order to adapt scan parameters to the object that is being imaged.

System and method for adaptive X-ray cargo inspection

A tapering enhanced stimulated superradiant amplification method and system which utilizes a strongly tapered undulator in reaching significant power outputs and conversion efficiencies. TESSA dramatically increases conversion/amplification efficiencies by violently (sharply) decelerating electrons and taking advantage of produced radiation to further drive interaction toward as it takes advantage of produced radiation to further drive interaction to increase overall radiation output. The system and method configures a strongly tapered undulator to operate in a new mode that is above normal input saturation levels to provide an amplified output with unexpectedly high efficiencies and power.

Tapering enhanced stimulated superradiant amplification

An additive manufacturing method for forming nearly monolithic SRF niobium cavities and end group components of arbitrary shape with features such as optimized wall thickness and integral stiffeners, greatly reducing the cost and technical variability of conventional cavity construction. The additive manufacturing method for forming an SRF cavity, includes atomizing niobium to form a niobium powder, feeding the niobium powder into an electron beam melter under a vacuum, melting the niobium powder under a vacuum in the electron beam melter to form an SRF cavity; and polishing the inside surface of the SRF cavity.

Additive manufacturing method for SRF components of various geometries

A method for testing the sensitivity of electronic components and circuits against particle and photon beams using plasma acceleration, in which the flexibility of the multifaceted interaction can produce several types of radiation such as electron, proton, ion, neutron and photon radiation, and combinations of these types of radiation, in a wide range of parameters that are relevant to the use of electronic components in space, such as satellites, at high altitudes or in facilities that work with radioactive substances such as nuclear power plants. Relevant radiation parameter ranges are accessible by this method, which are hardly accessible with conventional accelerator technology. Because of the compactness of the procedure and its versatility, radiation testing can be performed in smaller laboratories at relatively low cost.

A thermal imaging device is provided for converting an image in the terahertz radiation range to the visible range. In one embodiment, the device includes a converter having a thermochromic liquid crystal layer mounted on a sapphire base. In another embodiment, the device includes a thermal absorption layer including a metal selected from the group of iron, aluminum, tin, and copper. In a further embodiment, the device has an light source shaped as an annulus for illuminating a rearward surface of the converter, configured to permit visible light rays to pass through the annulus for capture by a digital detector. In a final embodiment, the device has a thermal adjustment device for adjusting the temperature of the thermochromic liquid crystal layer to an optimal temperature.

Terahertz camera

In an electron accelerator, a conductive housing defines a cavity. Photoelectrons are emitted from a photocathode into the cavity when light is applied to the photocathode. Via an opening formed in a wall of the conductive housing, the photoelectrons are output to the outside of the cavity. Coolant is flowed through a flow path formed in the wall of the conductive housing, to suppress a temperature rise of the conductive housing. The wall of the conductive housing is made by a metal additive manufacturing technique in such a way as to produce a flow path that has a gentle trajectory without discontinuities in gradient.
