In addition, such low energy electrons can contribute to the heat load of cryogenic systems in particle accelerators. When these particles get trapped in magnetic structures such as quadrupoles, wigglers and undulators, they can further exacerbate such effects. The study aims to better understand the conditions under which such electrons get trapped and for how long. This will be achieved by understanding the dynamics of such particles through perturbation analysis, and numerical tracking using the plasma simulation code Vorpal.

Low energy electrons, often referred to as electron clouds are known to cause detrimental effects on positively charged beams.
