Permeable Materials in the CLEO III Magnetic Field
نویسنده
چکیده
Two pairs of superconducting magnets will be inserted into CLEO as part of the CESR/CLEO phase III upgrade. Stray elds from the superconducting magnets will a ect the eld quality of the solenoid in the sensitive region of the CLEO detector. This problem was analyzed in [1]. In addition, the superconducting magnets will be supported by an active, high precision positioning system. Parts of the positioning system will be made from permeable materials which will magnetize in the CLEO eld and generate undesireable elds. These elds could a ect beam dynamics as well as the calibration of the drift chamber. An analysis of these e ects is presented in this paper.

متن کاملMagnetohydrodynamics Fluid Flow and Heat Transfer over a Permeable Shrinking Sheet with Joule dissipation: Analytical Approach
A laminar, two dimensional, steady boundary layer Newtonian conducting fluid flow passes over a permeable shrinking sheet in the presence of a uniform magnetic field is investigated. The governing equations have converted to ordinary nonlinear differential equations (ODE) by using appropriate similarity transformations. The main idea is to transform ODE with infinite boundary condition into oth...

متن کاملOn Global Energy Release Rate of a Permeable Crack in a Piezoelectric Ceramic
A permeable crack model is proposed to analyze crack growth in a piezoelectric ceramic. In this model, a permeable crack is modeled as a vanishing thin, finite dimension, rectangular slit with dielectric medium inside. A first-order approximation solution is derived in terms of the slit height, h0 . The main contribution of this paper is that the newly proposed permeable crack model reveals tha...
