Estimates for secondary electron emission and desorption yields in grazing collisions of gold ions with beam pipes in the BNL Relativistic Heavy Ion Collider: Proposed mitigation

Grazing collisions with the stainless steel beam pipes of gold ions, the so-called “halo scraping,” result in large secondary electron emission and surface molecular desorption yields in the Relativistic Heavy Ion Collider. Here we estimate electron emission yields as function of incidence angle, we...

description Grazing collisions with the stainless steel beam pipes of gold ions, the so-called “halo scraping,” result in large secondary electron emission and surface molecular desorption yields in the Relativistic Heavy Ion Collider. Here we estimate electron emission yields as function of incidence angle, we show that desorption rates will follow a similar angular dependence at small angles, and we propose a simple approach to mitigate these effects.
