Beamline X29: a novel undulator source for X-ray crystallography.
A high-flux insertion device and beamline for macromolecular crystallography has been built at the National Synchrotron Light Source (NSLS) that employs a mini-gap undulator source developed by the NSLS. The mini-gap undulator at beamline X29 is a hybrid-magnet device of period 12.5 mm operating at proven gaps of 3.3-10 mm. The beamline provides hard X-rays for macromolecular crystallography ex...
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...
متن کاملStatus 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 کاملBiological soft X-ray tomography on beamline 2.1 at the Advanced Light Source.
Beamline 2.1 (XM-2) is a transmission soft X-ray microscope in sector 2 of the Advanced Light Source at Lawrence Berkeley National Laboratory. XM-2 was designed, built and is now operated by the National Center for X-ray Tomography as a National Institutes of Health Biomedical Technology Research Resource. XM-2 is equipped with a cryogenic rotation stage to enable tomographic data collection fr...
