Aspects of Accelerator Vacuum Design and Some Applicable Examples to FRIB

Hsiao-Chaun (Dick) Hseuh, FRIB
Thursday, Nov 16, 12:30 PM - Accelerator Physics Seminar
NSCL Lecture Hall 1200

Abstract:  There are many types of particle accelerators with varying degrees of challenges to vacuum system designers. The vacuum technologies used in the research accelerators will be the focus of these talks. Part I (November 16) The fundamental vacuum physics parameters and formulae will be described. The source of gases, thermal outgassing, permeation and beam-induced gas loads will be presented. The types of high vacuum pumps commonly used for accelerators will also be presented. Part II –(future date) The selection of vacuum materials and treatment will be described. The vacuum system design, engineering, implementation and operation will be demonstrated through examples, some applicable to FRIB.
