Reducing Hls-ii Emittance by Radiation Damping Partition Factor Exchange∗

چکیده
In this paper, we present some preliminary studies on reducing the emittance of the Hefei light source II (HLS-II) storage ring by redistributing the synchrotron damping partition factor using a Robinson wiggler. The studies demonstrate that it is possible to reduce the emittance by 50% using a 2-meter long wiggler on a rematched lattice. This encouraging result suggests a feasible option to significantly improve the machine performance at a relative low cost.

Emittance Reduction via Dynamic RF Frequency Shift at the SLC Damping Rings
The generation of small emittance beams is a key issue determining the luminosity at a future linear collider. Dedicated damping rings have been designed to produce such beams, but techniques to further reduce the design emittances would yield immediate improvements in terms of higher luminosity. At injection into the damping rings, the transverse beam emittances are large and the beam fills a ...
متن کاملLimit on a horizontal emittance in high energy muon colliders due to synchrotron radiation . ∗
It is shown that at a 100 TeV muon collider the synchrotron radiation in the ring will determine the minimum horizontal emittance. In all ee storage ring the horizontal emittance is determined by quantum nature of the synchrotron radiation. Emission of photons in regions with non-zero dispersion leads to growth of the horizontal emittance while the average energy loss leads to the cooling. As t...

The Cornell Electron Storage Ring is the laboratory for the CESR Test Accelerator damping ring R&D program, and the source of x-rays for the Cornell High Energy Synchrotron Source. A peculiarity of the layout of the storage ring is that horizontal emittance is generated predominantly by the strong bends in the sextant of the ring that was designed with a long straight to accommodate the interac...

In a recent NDR machine experiment the transverse emittance was studied as a function of store time and tune. To explain the observed transverse emittance damping time constants, the magnetic measurement data of the longitudinal field of the bending magnets had to be taken intoaccount. The variation of the transverse emittances with tune due to misalignments and the associated anome lous~disper...
متن کاملA Lattice with Larger Momentum Compaction for the Nlc Main Damping Rings*
Previous lattice designs for the Next Linear Collider Main Damping Rings [1] have met the specifications for equilibrium emittance, damping rate and dynamic aperture. Concerns about the effects of the damping wiggler on the beam dynamics [2] led to the aim of reducing the total length of the wiggler to a minimum consistent with the required damping rate, so high-field dipoles were used to provi...
