Solenoid Effects on an Electron Cloud
نویسندگان
چکیده
Electron cloud due to beam-induced multipacting can generate transverse instabilities and beam size blow-up in both positron and proton accelerators. A solenoid satisfactorily suppresses multipacting in the drift region by confining the electrons close to the walls’ surface. There is a long drift region in the KEKB LER, wherein a solenoid occupies most of the beam’s pipe. We investigated the solenoid’s effects on the build-up of the electron cloud, the wake field and transverse coupled instabilities induced by electron cloud.

Electron Cloud Effects in Kekb
Measurements of the electron cloud effects in KEKB have been done since ECLOUD02 workshop. The results are summarized as 1) strength of the solenoid field in the present solenoid system is not enough to suppress the blow-up of the vertical beam size at high bunch currents and/or narrow bunch spacing, 2) solenoids in straight sections as well as arc sections contribute to suppress the electron c...
متن کاملElectron Cloud Studies for KEKB and ATF
I describe a few recent electron-cloud simulations for KEKB and the ATF. For KEKB the dependence of the electron build up on the peak solenoid field is studied, for the ATF the minimum bunch population required to build up an electron cloud in a possible future positron operation.
متن کاملThe Electron Cloud Instability Studies in Bepc*
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 ...
متن کاملNew Simulations of Positron-beam Electron Cloud Build- up and Electron-beam Coupled-bunch Instabilities for Kekb and Super-kekb
I summarize recent electron-cloud and coupled-bunch instability simulation studies for KEKB and SuperKEKB. The possible suppression of the electron-cloud build up inside quadrupole magnets by means of 4 permanent dipoles or by a super-imposed solenoid is investigated for the LER positron beam. Also studied is the electron accumulation in three different types of solenoidal fields, namely for a ...
متن کاملStudy of Coupled Bunch Instability Caused by Electron Cloud
Electron cloud induces a transverse wake force which makes a correlation between bunch by bunch, namely a transverse displacement of a bunch causes a perturbation of electron cloud, which affects the transverse motion of following bunches. The correlation can be regard as a kind of wake force. We study the coupled bunch instability caused by electron cloud in drift space and in weak solenoid fi...
