چکیده

Abstract This lecture introduces various kinds of spin rotating devices used in present particle accelerators. They include Siberian Snakes for polarization preservation and rotators creating a specific orientation experimental locations. Following the analysis rotation different types magnets, approaches designing are discussed. Considerations appropriate design choices dependence on beam energy given. Examples past accelerators as well designs considered future ones presented.

SNAKES, ROTATORS, SERPENTS, AND THE OCTAHEDRAL GROUPt

Specific configurations of horizontal and vertical bending magnets are given that, when acting on the spin polarization vector of a particle beam, generate a group of 24 operators isomorphic to the group of rotational symmetries of a cube, known as the octahedral group. Some of these configurations have the feature of converting transversely polarized beams to longitudinally polarized beams (or...

Outflows from magnetic rotators

The asymptotic structure of outflows from rotating magnetized objects confined by a uniform external pressure is calculated. The flow is assumed to be perfect MHD, polytropic, axisymmetric and stationary. The well known associated first integrals together with the confining external pressure determine the asymptotic structure. The integrals are provided by solving the flow physics for the base ...

Effects of Iranian Snakes Venom True Sea and Terrestrial Snakes on Some Bacterial Cultures

The antibacterial activities of eight snake crude venom (Macrovipera lebetina obtusa, Pseudocerastes persicus, Pseudocerastes urarachnoides, Echis carinatus sochureki, Gloydius halys caucasicus, Naja (naja) oxiana, and two species of true sea snakes Enhydrina schistose and Hydrophis cyanocinctus) were assessed against five important standard pathogenic bacterial strains (Escherichia coli, ...

Snakes and Caterpillars in Graceful Graphs

Graceful labelings use a prominent place among difference vertex labelings. In this work we present new families of graceful graphs all of them obtained applying a general substitution result. This substitution is applied here to replace some paths with some trees with a more complex structures. Two caterpillars with the same size are said to be textit{analogous} if thelarger stable sets, in bo...

’Slow’ and Fast Rotators Among Hypervelocity Stars

We measure the rotational velocities of the late B-type hypervelocity stars HVS7 and HVS8 from high resolution spectroscopy to be 60 ± 17 km s and 260 ± 70 km s. The ’slow’ rotation of HVS7 is consistent with an origin in a binary system, however, the fast rotation of HVS8 is more common of single B-type stars. Our results suggest that HVS8 could have been ejected by a mechanism other than that...
