Electron cloud dynamics in the Cornell Electron Storage Ring Test Accelerator wiggler
The interference of stray electrons (also called ‘‘electron clouds’’) with accelerator beams is important in modern intense-beam accelerators, especially those with beams of positive charge. In magnetic wigglers, used, for instance, for transverse emittance damping, the intense synchrotron radiation produced by the beam can generate an electron cloud of relatively high density. In this paper th...
متن کاملInvestigation of Chromaticity Sharing at the Cornell Electron Storage Ring
A potential advantage of the “Möbius” scheme, or any other strongly coupled lattice, is that the normal-mode oscillations are damped at rates which depend on both the horizontal and vertical chromaticities. This opens up the possibility of maintaining adequate damping even for quite negative chromaticity in one plane, provided the other is appropriately increased to compensate. This “chromatici...
متن کاملAn Upgrade for the Beam Position Monitoring System at the Cornell Electron Storage Ring
We describe the design and initial characterization of a fast (nanosecond time scale), high resolution (micron level) beam position monitoring system for use in the Cornell Electron Storage Ring (CESR). Beam position monitoring requirements at CESR include 1) precision orbit measurements in the interaction region and near the synchrotron xray beam lines, 2) monitoring of individual bunch positi...
متن کامل1 . 1 Colliding Beams at the Cornell Electron Storage Ring CESR
The electron-positron collider CESR was constructed as an upgrade to the Cornell Electron Synchrotron in the late 1970’s, originally designed to operate at 16 GeV center of mass with a maximum luminosity of 1x10 cm-sec. [1] The parameter list specified a single 100 mA (1.5x10 e-) bunch in each beam and beam-beam parameters of 0.06 in each plane. The fortuitous discovery of the Upsilon family of...
متن کاملBetatron phase and coupling measurements at the Cornell Electron/Positron Storage Ring
Errors in the lattice parameters of a storage ring can come from many sources. For example, the calibration constants used to set quadrupole magnets may be inaccurate, the orbit may pass through the sextupoles off center, or there may be unsuspected quadrupole fields associated with machine elements. To verify that a design lattice has actually been implemented correctly, one or more selected l...
