The Pohang Light Source (PLS) project was initiated in 1988 and its construction was completed in September, 1994 as the 5th facility of 3rd generation synchrotron radiation source in the world. Since the end of 1994, the PLS was operated with 2.0 GeV power till 1999, and upgraded its energy to 2.5 GeV in 2000. The number of users has rapidly been grown for last 15 years and their research outputs also steeply increased in number and significantly promoted in quality. Now the PLS has two main missions: one is to upgrade the current linear accelerator, storage ring and beamlines 'PLS-II' project, which has been started in 2009 and will be completed by the end of this year, and another to construct a X-ray free electron laser facility, "PAL-XFEL". It is sure that the PLS-II and PAL-XFEL become the major workhorses in the 21st century's polymer science and technology via leading and realizing ultra-small science and ultra-fast science. |
