Abstract Knowledge and control of the closed orbit in particle accelerators are of
fundamental importance for the optimization of machine performance. A survey is given of …

This work examines the effect of thermal and mechanical changes on the stability of the orbit
and size of the electron beam at the Taiwan Light Source (TLS). Most of the causes and …

Temperature variation is a major effect to the electron beam orbit stability. A series of studies
were conducted at the SRRC. A significant improvement was achieved by upgrading the …

This paper presents the air temperature analysis and control improvement for the large-
scale experimental hall, in which twenty-six beamlines currently located, at the Taiwan Light …

At the Taiwan Light Source (TLS), the stability of the electron beam orbit is sensitive to the
utility conditions. The beam position showed strong correlation with the temperature while …

This paper investigates the effect of cooling air flow on the positioning of magnet lattice at
the Synchrotron Radiation Research Center (SRRC). By CFD simulation code, the air flow …

The stability of the electron beam orbit had been observed to be sensitive to the utility
conditions. The stability of air temperature in the storage ring tunnel is one of the most critical …

Abstract Previously, the Taiwan Light Source (TLS) has proven that the temperature stability
of de-ionized cooling water is one of the most critical factors of electron beam stability. A …

Having been running the Taiwan Light Source (TLS) for fourteen years since it's opening in
1993, National Synchrotron Radiation Research Center (NSRRC), Taiwan has been …

Based on the thermal effects on the beam stability formerly studied, a series of measures are
taken to improve the air temperature control for the storage ring tunnel at the Taiwan Light …
