Bridges

Gusset plates are an essential component of steel bridges, used to connect beams and girders to the bridge columns, while also helping to strengthen the joint itself. Given the importance of the role these plates play among elements of a bridge's componentry, a serious issue in a gusset plate could be extremely hazardous to a bridge's structural health.

Nondestructive Evaluation Techniques : Radiography

Real-time radiography is a well-established method of NDT having applications in automotive, aerospace, pressure vessel, electronic, and munition industries, among others. The use of RTR is increasing due to a reduction in the cost of the equipment and resolution of issues

An experimental system for high temperature X

The primary constraint on the design was that of x-ray diffraction: no part of the system can interfere with either the incident or diffracted x-ray beams. The value of 2 θ c ‖ s shown in Fig. Fig.1 1 has a maximum value of 15: a value based on the detector size (410 mm 410 mm) and the typical working distance in the A2 station of 700 mm.

2017/5/16The great majority of CT systems use X-ray tubes, although tomography can also be done using a synchrotron or gamma-ray emitter as a monochromatic X-ray source. Important tube characteristics are the target material and peak X-ray energy, which determine the X-ray spectrum that is generated; current, which determines X-ray intensity; and the focal spot size, which impacts spatial

Journal of Physics B: Atomic, Molecular and Optical Physics,

Such x-ray sources usually require production of high-quality electron beams from compact accelerators. Guiding a radially polarized laser pulse in a plasma waveguide has been proposed for realizing direct laser acceleration (DLA), where the electrons are accelerated by the axial electric field of a co-propagating laser pulse (Serafim et al 2000 IEEE Trans. Plasma Sci. 28 1190 ).

Helical light: Interference and tweezers

Researchers have known for some time of monochromatic light beams, such as Laguerre-Gauss beams, which carry orbital angular momentum also have a helical phase profile. According to Ole Steuernagel of the University of Hertfordshire's Science and Technology Research Institute, UK, have helical wave fronts and can be made visible using interferometry.
