Beam loading is the conventional term for the effect of beam passage through an RF cavity installed for the control of some beam parameters such as energy, bunch length, energy spread, etc... The fields developed in such a structure and their effect on the beam can be analyzed as for all other discontinuities of the vacuum chamber. In particular, F. Sacherer's theory of impedances and beam inst...

Spatial intensity distribution is one of the fundamental parameters that indicate how a laser beam will behave in an application. For example, in a materials processing situation, it is easily understandable why two beams of identical power and diameter leave different burn marks on a substrate if one beam features a Gaussian or near-Gaussian profile (maximum intensity in the beam center), whil...

In this research the sensitivity analysis of the geometric parameters such as: length, thickness and width of a single link flexible manipulator on maximum deflection (MD) of the end effector and vibration energy (VE) of that point are conducted. The equation of motion of the system is developed based on Gibbs-Appel (G-A) formulation. Also for modeling the elastic property of the system the ass...

The laser cutting parameters are dependent on the beam characteristics, the cutting rate required, the composition and thickness of the material to be cut, and the desired cut edge quality. The laser cutting process and cut quality depend upon the proper selection of laser and workpiece parameters. Deficiencies in cutting quality may be related to the slow process drifts and disturbances that a...

The present study is the first to analyze the dynamic response of a poroelastic beam subjected to a moving force. Moreover, the influences of attached mass-spring systems and non-ideal supports (with local movements in the supporting points or base due to the presence of factors such as gaps, unbalanced masses, and friction or seismic excitations) on the responses were investigated. Non-ideal s...

In this research work, investigations are carried out on Continuous Wave (CW) Nd:YAG laser welding system after preliminary experimentation to understand the influencing parameters associated with laser welding of AISI 304. The experimental procedure involves a series of laser welding trials on AISI 304 stainless steel sheets with various combinations of process parameters like beam power, beam...
