Beam lifetime investigations at SRRC

PDF Version Also Available for Download.

Description

The beam lifetime of the 1.3 GeV storage ring TLS (Taiwan Light Source) at SRRC was studied. Contributions of the gas scattering lifetime and Touschek scattering lifetime were measured. Effects of insertion devices, RF energy acceptance, chromaticity setting, transverse emittance coupling strength, bunch length, bunch current, etc. on the beam lifetime were measured. It is observed that this machine is Touschek lifetime dominated provided that the transverse emittance coupling strength is low enough and bunch current is reasonably high. In the multibunch users mode it is required to have a longer lifetime; some possible actions to increase beam lifetime have ... continued below
