Impact of deconditioning on the secondary electron yield of Cu surfaces in particle accelerators

Physical Review Accelerators and Beams, 2020
Electron cloud is a critical phenomenon in particle accelerators operating with high intensity and positively charged beams, as it is responsible for beam instabilities, vacuum degradation, and heat load on cryogenic sections.

Characteristics of secondary electron emission and multipactor from a nested microtrap structure surface

AIP Advances, 2021
It is known that an appropriate surface structure can suppress the secondary electron emission as a result of the receded multipactor in a spacecraft microwave component. On the other hand, the multiplier effect caused by electron re-entrance in ordinary

Carbon coatings with low secondary electron yield

Vacuum, 2013
Carbon thin films for electron cloud mitigation and anti-multipacting applications have been prepared by dc magnetron sputtering in both neon and argon discharge gases and by plasma enhanced chemical vapour deposition (PECVD) using acetylene. The thin films have been characterized using Secondary Electron Yield (SEY) measurements, Scanning Electron ...

Amorphous carbon coatings for the mitigation of electron cloud in the CERN Super Proton Synchrotron

Physical Review Special Topics. Accelerators and Beams, 2011
Electron cloud buildup is a major limitation for high-energy particle accelerators such as the CERN Super Proton Synchrotron (SPS). Amorphous carbon thin films with low initial secondary electron yield (SEY≅1.0) have been applied as a mitigation material
