Optimization of Elliptical SRF Cavities for β < 1
Elliptical superconducting radio-frequency (SRF) cavities are widely used for accelerating electrons and positrons that travel close to the speed of light (β = v/c ≈ 1). For the acceleration of heavier particles, such as protons and ions, β can be considerably less than one. In these cases there are many different cavity designs used, with the choice depending upon the respective goals and cons...
متن کاملTorsion of Elliptical Composite Bars Containing Neutral Coated Cavities
Using complex variable methods and conformal mapping techniques, we establish the existence of coated cavities of various shapes that do not disturb the warping function in a host elliptical bar. These cavities are known as ‘partly neutral cavities’. Our results show that the two axes corresponding to the neutral elliptical coating are parallel to those of the host elliptical bar and that the c...
متن کاملConstructal Theory Applied to the Geometric Optimization of Elliptical Cavities into a Solid Conducting Wall
This work reports, according to Bejan’s Constructal theory, the geometric optimization of an elliptical cavity that intrudes into a solid conducting wall. The objective is to minimize the global thermal resistance between the solid and the cavity. There is uniform heat generation on the solid wall. The cavity is optimized for two sets of thermal conditions: isothermal cavity and cavity bathed b...
متن کاملReliability analysis of tube hydroforming process
In this paper, we propose a reliability–mechanical study combination to treat the tube hydroforming process (THP). This process consists to apply an inner pressure combined to an axial displacement to manufacture the part. Our goal is the computation of the failure probability of the hydroforming process. Normally, this process is particularly complex and have to be solved numerically. There ar...
متن کاملSimulative Analysis of Tube Hydroforming Process
The tube hydro forming process (THF) is an unconventional metal forming process, where in tube is deformed internally and thus it is forced to expand and conform to the shape of the surrounding die. The performance of this process depends on various parameters like internal pressure, axial loading etc. For FEA simulation, it requires proper combination of material selection, part design and bou...
