New apparatus for precise synchronous phase shift measurements in storage rings
Measuring a synchronous phase shift as a function of beam current is commonly done in accelerator physics to estimate the longitudinal impedance of a storage ring vacuum chamber. This measurement is normally done with RF techniques that don’t have enough accuracy to detect small phase shifts typical to the newer storage rings. In this paper we report results from a new method for precise measur...
متن کاملEmittance Measurements in Low Energy Storage Rings
The development of the next generation of ultra-low energy antiproton and ion facilities requires precise information about the beam emittance to guarantee optimum performance. In the Extra-Low ENergy Antiproton storage ring (ELENA) the transverse emittances will be measured by scraping. However, this diagnostic measurement faces several challenges: non-zero dispersion and systematic errors due...
متن کاملLuminosity and Tune Shift in e + e - Storage Rings
Luminosity and tune shift have been the subject of numerous papers and talks since the invention of electron-positron storage rings. In this paper we derive an equation for luminosity and one for the linear tune shift based upon two simple assumptions. The first assumption is that the storage ring be designed such that the linear tune shifts in the two transverse planes, x and y, are equal; i.e...
متن کاملMass and lifetime measurements of exotic nuclei in storage rings.
Mass and lifetime measurements lead to the discovery and understanding of basic properties of matter. The isotopic nature of the chemical elements, nuclear binding, and the location and strength of nuclear shells are the most outstanding examples leading to the development of the first nuclear models. More recent are the discoveries of new structures of nuclides far from the valley of stability...
