Abstract: A structurally robust radiation detection system is provided, the system having a radiation detector, a first encasement encasing the radiation detector, a second encasement encasing the first encasement, and a pair of rigid support frames each configured to couple the first encasement to the second encasement such that the first encasement does not contact the second encasement, the support frames respectively comprising an inner ring configured to be coupled to the first encasement, an outer ring configured to be coupled to the second encasement, and a plurality of curvilinear connecting members connecting the inner ring to the outer ring, the connecting members being periodically spaced apart along a circumference of each of the inner and outer rings and respectively configured to have connecting points at the inner ring that are radially offset from corresponding connecting points at the outer ring.

Abstract: A lightweight handheld radiation detector for use in detecting radioactive materials, including a cylindrical vacuum housing having an inner volume, a detector material encasement disposed within the inner volume, a cooling element disposed within the inner volume and integrally formed with the detector material encasement to cool detector material within the detector material encasement.

Abstract: A salient pole machine and method of forming the same comprising a rotating field assembly and at least one inter-pole cap connected to the rotating field assembly and/or at least end coil cap connected to the rotating field assembly. Each inter-pole cap preferably includes a top surface that has a curvature and/or at least one cavity. Each end coil cap may include at least one support. The salient pole machine may also include at least one fan assembly independent of the rotating field assembly. In a preferred embodiment, the salient pole machine includes at least one mounting plate, wherein each fan assembly is mounted on the mounting plate. The inter-pole caps and the end coil caps preferably comprise composites, polymers, alloys, ceramics, or naturally occurring materials.

Abstract: A rotor assembly for a generator includes a rotor hub, a first rotor pole, a second rotor pole, and an element (e.g., wedge). Each rotor pole extends from the rotor hub, and includes a winding of conductive wire coupled thereto and a pole head. The pole head is positioned on an end of the rotor pole opposite to the hub, and the pole head has an arcuate outer periphery. The element is positioned between the first and second rotor poles, and includes an open volume and an aperture. The open volume is formed in the element, and is positioned proximate to the windings of the first and second rotor poles. The aperture is on an outside portion of the element, and provides access to the open volume such that air may travel to and from the open volume for cooling of the rotor assembly. The outside portion of the element is substantially flush with at least one of the pole heads, and is contoured to continuously extend the arcuate outer periphery of the at least one of the pole heads.
