Abstract :
HLS (Hefei light source) is a dedicated synchrotron radiation research facility, spectrally strongest in VUV and soft X-ray, designed and constructed in 1980´s, accepted to regular service in 1991. From 1999 to 2004, the National Synchrotron Radiation Laboratory carried out Phase II Project, in which quite a few sub-systems in HLS were upgraded and 8 new beamlines were constructed. After Phase II Project, the operation reliability and performance of HLS is improved considerably, for example, the operation beam current is above 250 mA, beam lifetime is longer than 8 hours, orbit stability met the requirement of users, and fault time of machine operation is much less than before. The capability of HLS to serve synchrotron radiation users is enhanced significantly. The main tasks of machine study in HLS are introduced briefly.
