Abstract The number of mirror segments, geometry and orientation are essential parameters when assessing the beam-shaping capabilities deformable mirrors. Here, we use a Liquid Crystal on Silicon Spatial Light Modulator (LCoS-SLM) to mimic mechanical design quantitatively analyse effect segments their geometrical structure resulting structured modes. Our approach can be used as test bed prior d...

The diiculty encountered in designing an interaction region (IR) for a 2-TeV Muon Collider lies in the extreme constraints placed on beam parameters at the point of collision. This paper examines a relaxation of the interaction-point criterion insofar as it impacts luminosity, the design, and stability of the interaction region.

This project involves using mathematical models to optimize the performance of a diffractive optical element. Unlike the usual optimization problem, we will seek methods for finding an optimal design in the presence of environmental variability. Sources of variability can include changes in manufacturing or operating conditions. The methods will be applied to designing a diffractive optical ele...

Introduction: In electron beam treatment, because of the non-point electron beam source, inverse-square law cannot be applied for dosimetry in different treatment intervals. Therefore, providing source-surface distance (SSD) charts in all clinics is of paramount importance. This study aimed to determine the effective SSD for various electron beam energies and field sizes and to...

In this research static deflection and free vibration of homogeneous nanobeams coated by a functionally graded (FG) layer is investigated according to the nonlocal elasticity theory. A higher order beam theory is used that does not need the shear correction factor. The equations of motion (equilibrium equations) are extracted by using Hamilton’s principle. The material properties are considered...

The design requirements for current heavy-particle accelerators operated within a hospital to deliver radiation therapy must satisfy both clinical and research needs. Advances in dedicated beam delivery systems for clinical utilization and biological studies add requirements that previous accelerators did not have. Eight years experience using the Loma Linda University proton facility has empha...
