INSTALLATION FOR MEASUREMENTS OF SECONDARY EMISSION YIELD AND ELECTRON CLOUD LIFETIME IN MAGNETIC FIELD

An experimental setup for investigations of electronsurface interaction and electron cloud behaviour is under commissioning at BINP. The proposed method provides direct measurements of secondary emission yield and electron clouds lifetime in the presence of strong magnetic field. In principle, the experiments can be performed at cryogenic temperatures. The experimental data will help to figure out the process of reflection of low energy electrons from a metal surface and can be useful for improvement of computer codes developed for simulation of electron clouds behaviour in a cold beam pipe of particle accelerators. The structure and performance capabilities of the setup are described, first experimental results are presented.
