The operational status of Pohang Light Source

From the year 2000, the PLS storage ring stores 2.5 GeV high-energy electron beam by raising the energy from the 2.0 GeV injection energy. The stored current is presently 180 mA, which is limited by the available RF energy at 2.5 GeV. In May 2000, we succeeded in storing 300 mA at 2.0 GeV achieving the last design goal of PLS. Further, the new record of the maximum beam current, 450 mA, was made in April 2001. At present, PLS has 13 beamlines in operation, 1 beamline under commissioning and 6 beamlines under construction. Other progresses and issues of the PLS operation will be discussed further.
