Electron induced molecular desorption from electron clouds at the Relativistic Heavy Ion Collider

Abstract

Molecular desorption coefficients from electron bombardment of the warm Relativistic Heavy Ion Collider beam pipe are derived from measurements for both baked and unbaked stainless steel. For this, we analyze electron detector and pressure gauge signals in the presence of an electron cloud. Finally, we present a comparison between the measured and simulated energy spectrum of the cloud electrons.
