New Method of Dispersion Correction in the Pep-ii Low Energy Ring
نویسنده
چکیده
The sextupole magnets in the Low Energy Ring (LER) of PEP-II are grouped in pairs with a phase advance of 180 degrees. Displacing the magnets or moving the orbit to displace the beam in the magnets in an antisymmetric way creates a dispersion wave around the ring. This can be used to correct the vertical dispersion in LER without changing the local coupling. Results from simulations are shown.

PEP-N: A 0.8 GeV × 3.1 GeV Collider at SLAC
The PEP-N project is a proposed new e+e− collider at SLAC to operate in the center of mass energy range of 1.0 GeV to 3.1 GeV. PEP-N consists of a new Very Low Energy electron Ring VLER (< 800 MeV) to collide with the PEP-II e+ Low Energy Ring LER (3.1 GeV) parasitically to PEP-II operation for BaBar. Since the e+ ring has a fixed energy, the very low energy ring needs an energy range of 100 Me...
متن کاملCommissioning the 90◦ Lattice for the Pep Ii High Energy Ring∗
In order to benefit from further reduction of the vertical IP beta function of the PEP-II high energy ring (HER) the bunch length should be reduced. This will be achieved by changing the phase advance from 60◦ to 90◦ in the four arcs not adjacent to the IR region, thus reducing momentum compaction by about 30% and reducing bunch length from a present 12 mm down to 8.5 mm at low beam current. In...
متن کاملThe PEP-II Project: Low-Energy Ring Design and Project Status
We describe the present status of the PEP-II project. The project comprises four major systems: Injector, High-Energy Ring (HER), Low-Energy Ring (LER), and Interaction Region (IR). We focus in detail on the design of the LER, as its parameters and requirements are most closely related to those required for the Beijing Tau-Charm Factory rings. The PEP-II LER is a high-current, 3.1-GeV positron ...
متن کاملOptics Characterization and Correction at Pep-ii
The linear optics of both the high energy ring (HER) and low energy ring (LER) for SLAC’s PEP-II B-Factory were characterized with two algorithms: analysis of the measured closed orbit response matrix and analysis of betatron phase advance measurements. The results of the two analyses were in good agreement. When the HER was first run in a low optics in autumn 1997, the measured functions showe...
