Abstract: This note describes the use of the program ECloud for the simulation of the electron cloud build up, which occurs due to photoemission, ionization, and secondary emission inside an accelerator beam pipe during the passage of a narrowly spaced proton or positron bunch train. All input parameters as well as the standard output files are explained. The goal of the note is to facilitate installation and execution of the program with a minimum knowledge of its internal structure.

Electron cloud simulations: beam instabilities and wakefields
Giovanni Rumolo,Frank Zimmermann +1 more
TL;DR: The HEADTAIL simulation program as discussed by the authors is a simulation program developed at CERN which is aimed at studying the single-bunch instability arising from the interaction on successive turns of a single bunch with the cloud generated by the previous bunches.
PyECLOUD and build-up simulations at CERN
TL;DR: PyECLoudd as discussed by the authors is a newly developed code for the simulation of the electron cloud (EC) build-up in particle accelerators, which is mostly based on the physical models already used in the ECLOUD code but exhibits a significantly improved performance in accuracy, speed, reliability and flexibility.

Simulation of the electron-cloud build up and its consequences on heat load, beam stability and diagnostics
TL;DR: In this paper, the authors investigate the electron-cloud build up and related effects via computer simulation, where macroparticles representing photoelectrons are emitted synchronously with the passing proton or positron bunch and are subsequently accelerated in the field of the beam.

TL;DR: In this article, the secondary electron emission of surfaces exposed to the impact of energetic electrons contributes significantly to the electron cloud build-up for the prediction of the consequences of this effect, and the results of experiments showing the variation of the electron induced degradation yield with the incident electron dose will be compared to the concomitant reduction of thesecondary electron yield.
