The Electron Cloud Instability Studies in Bepc*

چکیده
The electron cloud instability (ECI) in the BEPC was studied systematically with experiments and simulations in recent years. Several electron cloud detectors have been installed into the BEPC storage ring to measure the electron yielding. The effects of solenoid, the clearing electrode, the chromaticity and the octupole on ECI have been investigated in BEPC experimentally. To evaluate the ECI in BEPCII, the upgrade project of BEPC, a computer code has been developed to simulate the electron density in the antechamber under different conditions, as well as the progress of the single bunch and coupled bunch instabilities caused by the electron cloudy. The experimental and simulation results, as well as the activities are reported in this paper.

Photoemission Instabilities: Theory and Experiment
Synchrotron radiation in electron-positron colliders and synchrotron light sources ejects photoelectrons from the beam chamber walls. The resulting cloud of slow photoelectrons interacts with the beam, and may generate a transverse coupled bunch instability. In some high current storage rings a photoemission effect causes the dominant transverse instability, with a sub-millisecond risetime. Two...
متن کاملRecent Studies on Beam-photoelectron Instability in Bepc
An experiment investigating the photoelectron instability has been performed in BEPC at IHEP, China. The betatron oscillation of each bunch was observed and recorded by a single pass beam position monitor system which has a capability to measure the transverse position of every bunch over 16000 turns. The effect of an octupole magnet on the instability was also studied. This paper describes res...
متن کاملThe Proposed Experimental Study on Beam- Photoelectron Interactions in Bepc
A vertical collective effect suspected as photoelectron instability (PEI) has been observed at Photon Factory (PF) of KEK in recent years. This phenomena may impose a limitation on the performance of the proposed B-Factories or T-c Factories. An experiment has been planned to test it using positron beam at Beijing Electron Positron Collider (BEPC) in 1996 under the cooperation between IHEP and ...

Electron cloud has been identified as one of the highest priority issues for the international Linear Collider (ILC) Damping Rings (DR). An electron cloud Working Group (WG) has evaluated the electron cloud effect and instability, and mitigation solutions for the electron cloud formation. Working group deliverables include recommendations for the baseline and alternate solutions to the electron...
متن کاملElectron-Cloud Instability and Beam-Induced Multipacting in the LHC and in the VLHC*
fin the beam pipe of the Large Hadron Collider (LHC), photoemission and secondary emission give rise to a quasistationary electron cloud, which is established after a few bunch passages. The response of this electron cloud to a transversely displaced bunch resembles a short-range wakefield and can cause a fast instability [l]. In addition, beam-induced multipacting of the electrons may lead to ...
