Mechanical Induced Beam Motion in Srrc Storage Ring
It had been observed that the mechanical stability of some magnets had influences on the closed orbit in the storage ring. In this paper, a mechanical shaker in low vibration level was applied on the quadrupole magnet. The perturbation of the closed orbit was measured. The thermal induced distortion of magnet supporting structure was discussed. The motions of BPM and quadrupole magnet were meas...
متن کاملX-band Crab Cavities for the Clic Beam Delivery System
The CLIC machine incorporates a 20 mrad crossing angle at the IP to aid the extraction of spent beams. In order to recover the luminosity lost through the crossing angle a crab cavity is proposed to rotate the bunches prior to collision. The crab cavity is chosen to have the same frequency as the main linac (11.9942 GHz) as a compromise between size, phase stability requirements and beam loadin...
متن کاملHarmonic Cavities and Longitudinal Beam Stability in Electron Storage Rings∗
Harmonic cavities have been used in storage rings to increase beam lifetime and Landau damping by lengthening the bunch. The need for lifetime increase is particularly great in the present generation of low to medium energy synchrotron light sources where the small transverse beam sizes lead to realitively short lifetimes from large-angle intrabeam ( Touschek) scattering. We review the beam dyn...
متن کاملOne-dimensional beam ordering of protons in a storage ring.
The ordering of protons has been observed at a new storage ring, S-LSR, at Kyoto University. Abrupt jumps in the momentum spread and the Schottky noise power were observed for protons for the first time at a particle number of approximately 2000, upon applying electron cooling with electron currents of 25, 50, and 100 mA. The transition temperature was 0.17 and 1 meV in the longitudinal and tra...
متن کاملLongitudinal Momentum Mining of Beam Particles in a Storage Ring
I describe a new scheme for selectively isolating high density low longitudinal emittance beam particles in a storage ring from the rest of the beam without emittance dilution. I discuss the general principle of the method, called longitudinal momentum mining, multiparticle beam dynamics simulations and results of beam experiments. Multi-particle beam dynamics simulations applied to the Fermila...
