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,...
متن کاملOperational Status of the Pohang Light Source*
Since 1995, the Pohang Light Source has been serving as the unique synchrotron radiation facility in Korea. In 2001, beam time scheduled for users was 4,056 hours. The actual beam time supplied to users was 3,806 hours recording a beam availability of 93.8%. Number of beamline experiments was 292, carried out by 1,087 users. On the technical side, the most important issue in PLS operation is th...
متن کاملBeam Lifetime of the Pohang Light Source
Like other third generation light sources, main contributions to the be am lifetime of the Pohang Light Source come from the beam-gas scattering and the Touschek effect. The beam-gas scattering lifetime is measured with extremely low stored current in the long train of bunches. By investigating the vertical gap dependence of the beam-gas scattering lifetime, it i possible to decompose the beam-...
متن کاملOperational Status of the Pohang Light Source
From the year 2000, the PLS storage ring stores 2.5GeV high-energy electron beam by ramping the energy from the 2.0GeV injection energy. The maximum stored current is presently 200mA at 2.5GeV, which is limited by the available RF energy. In May 2000, we succeeded in storing 300mA at 2.0GeV achieving the last design goal of the PLS. Further, the new record of the maximum stored beam current of ...
متن کاملTop-up operation at Pohang Light Source-II.
After three years of upgrading work, PLS-II (S. Shin, Commissioning of the PLS-II, JINST, January 2013) is now successfully operating. The top-up operation of the 3 GeV linear accelerator had to be delayed because of some challenges encountered, and PLS-II was run in decay mode at the beginning in March 2012. The main difficulties encountered in the top-up operation of PLS-II are different leve...
