It is not unusual to place multiple accelerators in a common enclosure to save on civil construction costs. This often complicates operations, especially if accelerators are affecting each other. At Fermilab, the influence of a rapidly cycling Main Injector (MI) synchrotron on an antiproton storage ring (Recycler), placed in a common tunnel, was initially found to be unacceptable for a reliable...

In this work, to characterize the radiated emission from electronic circuits in shielding enclosure, an improved electric dipole-based source reconstruction method (SRM) is developed. Moreover, by resorting reconstructed equivalent source, estimation of electromagnetic interference (EMI) between different circuit modules enclosure can be conveniently and accurately evaluated. Different free-spa...

Electromagnetic compatibility (EMC) has become much more important especially over the last decade due to incorporating advanced driver assistance and electric propulsion systems into conventional vehicle architecture. shielding is a conductive barrier used for protecting electronic circuits against external electromagnetic interference (EMI). Shielding effectiveness (SE) measure of performance...

An analytical formulation has been developed to evaluate the shielding effectiveness (SE) of two coplanar rectangular metallic enclosures with a circular aperture excited by an internal electric dipole source. The formulation consists of three parts: First, the near-field electromagnetic interference (EMI) of the electromagnetic leakage from the aperture is represented by the electric dipole in...

Abstract This paper presents the results of our experiment, which consisted in measurement shielding effectiveness a camera enclosure that was designed and constructed order to increase susceptibility against external electromagnetic fields. All activities, from defining requirements final design measurements, were performed Laboratory Electromagnetic Compatibility at Faculty Applied Informatic...

This Note describes calculations of the shielding necessary to reduce the dose rate to less than 0.05 mrem/h when synchrotron radiations emitted by the LCLS electrons beam hit a worst type scattering target located in the hard X-ray line. The calculations were performed using the FLUKA Monte-Carlo code and as well as the STAC8 analytical code. The photon spectrum used as a source term correspon...
