Soft X-Ray Undulator
Abstract
This is the second annual report for a two-year program to base a soft x-ray undulator at the vacuum ultra-violet (VUV) storage ring at the National Synchrontron Light Source (NSLS). The undulator will be used as a radiation source by multi-institutional research teams to perform the first spin-polarized photoemission experiments in the United States. The undulator source will permit major advances to take place in materials research in the forefront area of novel, ultra-thin magnetic films and surfaces. The two most important achievements are that contracts have been negotiated both for the undulator and vacuum chamber that the undulator encases. Included is a timetable that shows the undulator installation on the NSLS VUV ring as taking place during the scheduled February, 1991 shutdown of the ring. The vacuum chamber is being fabricated by NSLS. Plans are underway at Argonne to design a methodology for testing the undulator performance on the VUV ring. It will conclude monitoring the characteristics of the high-harmonic radiation output, because of its sensitivity to the magnetic design errors. Comparisons will be made to the performance of other insertion devices, with the hope that the data will permit future device design to benefit from past experience.
