Radiation protection at synchrotron radiation facilities.
A synchrotron radiation (SR) facility typically consists of an injector, a storage ring, and SR beamlines. The latter two features are unique to SR facilities, when compared to other types of accelerator facilities. The SR facilities have the characteristics of low injection beam power, but high stored beam power. The storage ring is generally above ground with people occupying the experimental...

With the successful commissioning and achievement of significant milestones at both the 7-GeV Advanced Photon Source (APS) at Argonne National Laboratory and the 1.5-GeV Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory, synchrotron radiation research capability in the United States holds the promise of many important discoveries in the decade to come. An overview of current ...
متن کاملSynchrotron Radiation and Pretzeled Orbits Geometry of Synchrotron Radiation Illumination
Turning on a `pretzel' , or any closed orbit distortion, can substantially alter the path of synchrotron radiation (SR), in some instances causing it to strike components not designed to absorb the radiation. In this paper I develop equations useful in determining the source position and angle of dipole SR as a function of the pretzel amplitude and angle. Formula for linear power deposition and...

We calculate the emission rate and spectrum for radiation of neutral electroweak bosons (Z”) f rom an electron in a weak external homogeneous electromagnetic field satisfying 1 f Fcly Fp”/1/2 < Fc 3 mzc3/eti. The calculational method is based on the source theory formulation of quantum field theory introduced by Schwinger. In particular for ultra-relativistic electrons, we find that the 2’ emis...
