Status of Pohang Light Source

The Pohang Light Source (PLS) is a national users’ facility for basic and applied science research using synchrotron radiation. It consists of a 2-GeV linac as a full-energy injector and a low-emittance, thirdgeneration storage ring. It has been serving users since September of 1995. The beamlines have been increased from two to eight units as the increased number of users. The first undulator, U7 was installed in July 1997. In order to reduce the HOMs from RF cavities, we installed a new precision cooling system for RF cavities. We are also a preparing longitudinal feedback system to reduce the beam instabilities. We will introduce recent activities to improve PLS performances and key statistics in the machine operations.
