Quasi-isochronous storage rings

Quasi-isochronous storage ring

In tins article we study the possibility of designing storage rings with a reduced by two or more orders of magnitude with respect to existing rings, thus making the bunch length shorter by a factor of 10 or more . We will, with an appropriate design, show that this bunch length reduction can be achieved while simultaneously increasing the beam peak current. With this approach one can increase ...

Collective Effects in Isochronous Storage Rings

We studied the collective instabilities in isochronous storage rings using a linac-type analysis. Simple criteria for avoiding the longitudinal and transverse instabilities are developed by employing a two-particle model. Numerical examples show that these conditions do not impose serious performance restrictions for two of the currently proposed isochronous storage rings. Presented at ICFA Wor...

Storage Rings.

The design, construction, and performance of a streamer-chamber system for the study of inelastic proton-proton collisions at the CERN ISR are described. The chambers have specially shaped ground electrodes to accommodate the ISR vacuum chamber and to obtain an almost 4r~ solid angle. Problems arising from the non-fiat electrodes and the insertion of converter plates into the sensitive volume o...

Quasi-Primitive Rings and Density Theory

Quasi - Reduced Rings

Let R be an arbitrary ring with identity. In this paper, we introduce quasi-reduced rings as a generalization of reduced rings and investigate their properties. The ring R is called quasi-reduced if for any a, b ∈ R, ab = 0 implies (aR) ∩ (Rb) is contained in the center of R. We prove that some results of reduced rings can be extended to quasi-reduced rings for this general settings. 2010 Mathe...
