WebMar 4, 2002 · Pohang Accelerator Laboratory (PAL) is developing an Elliptically Polarized Undulator (EPU) to produce polarized synchrotron radiation at Pohang Light Source (PLS). The EPU6 is an Apple-II type elliptical undulator, which changes the polarization of the field by translating the quadrant arrays. The PLS EPU6 features a period of 6 cm, a … WebJul 21, 2001 · Introduction. During 1998/99 three beamlines of the UE56-PGM type were built at BESSY-II to meet the increased need for synchrotron radiation of tuneable, i.e. linear circular, polarization. Each beamline is located on a dual Sasaki type elliptical polarizing undulators [1], [2] and are based on a plane grating monochromator design which works ... spray bottle makeup factories
