Six-dimensional matching of intense beam with linear accelerating structure [PDF]
Nuclear Instruments and Methods in Physics Research, A 995 (2021)
165074, 2021 Beam matching is a common technique that is routinely employed in accelerator design with the aim of minimizing beam losses and preservation of beam brightness. Despite being widely used, a full theoretical understanding of beam matching in 6D remains elusive. Here, we present an analytical treatment of 6D beam matching of a high-intensity beam onto an

Nondestructive Evaluation of Damage in Beams Using Displacement Curvature [PDF]
Journal of Rehabilitation in Civil Engineering, 2013 In this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in Euler-Bernoulli beams are assessed. Static response of a beam is obtained using the finite element modeling. In
