OPERATIONAL STATUS OF THE POHANG LIGHT SOURCE

摘要

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 450mA at 2.0GeV was made in April 2001. Scheduled beam time to users in the PLS was 4,224 hours in 2000. The actual beam time available to users was 3,834 hours with a beam availability of 90.9%. The beam availability during operation in the first half of 2001 was improved to 93.6% that was the result of various improvements discussed here. At present, the PLS has 14 beamlines in operation and 9 beamlines under construction. A total of 237 experiments was carried out by 883 users in 2000.
