Electron Cloud Buildup in the Isis Proton Synchrotron and Related Machines
نویسنده
چکیده
Electron cloud formation and the associated effects of beam loss and instabilities have been observed in high intensity proton machines such as the LANL PSR and the CERN SPS. A program has recently been launched at the Rutherford Appleton Laboratory (UK) to understand the lack of electron cloud induced instabilities in the operations of the 160 kW 70-800 MeV ISIS synchrotron. Simulations have been carried out using a newly developed version of the CERN ECLOUD code [1, 2] to model the main features of the electron cloud build-up in a representative field-free region of the ISIS ring. A comparative study has also been undertaken to gauge electron-proton (e-p) related problems/limitations in possible future proton machines for spallation neutron sources (ESS) or neutrino factories (ISIS MW upgrade).

This report is a brief summary of the session D of the workshop ECLOUD04 about electron cloud build up simulations (Part I). In this session the status of some of the existing codes for the build up simulations has been reported and updates on the progress towards new powerful 3D and self-consistent codes have been presented. Simulations specifically applied to damping rings for linear collider...
متن کاملComparative Simulation Studies of Electron Cloud Build-up for Isis and Future Upgrades
Electron cloud effects currently limit the performance of several proton accelerators operating with high beam current. Although ISIS, the 160 kW 70–800 MeV proton synchrotron at the Rutherford Appleton Laboratory (UK), has never appeared to be affected by the problem in its 20 years of operations, e-p instabilities could potentially be a cause of concern for future machine upgrades to higher b...
متن کاملA Preliminary Comparative Study of the Electron - Cloud Effect
We present preliminary electron-cloud simulation results for the Proton Storage Ring (PSR) at LANL, the ISIS synchrotron at RAL, and the European Spallation Source (ESS). For each machine, we simulate the build-up and dissipation of the electron cloud (EC) in a representative field-free section of the vacuum chamber. For all three cases, we choose the same residual gas temperature, secondary em...
متن کاملElectron cloud buildup and instability: Numerical simulations for the CERN Proton Synchrotron
Gas ionization and electron multiplication due to the secondary-emission process on the inner side of the beam pipe may induce the buildup of an electron cloud, which can significantly degrade the performance of rings operating with closely spaced proton or positron bunches. The undesired electron cloud causes pressure rise and beam instability when the parameters are pushed above certain thres...
