Magnetic measurements of the NSLS (National Synchrotron Light Source) soft x-ray undulator

The Soft X-Ray Undulator Magnet was installed in the X-ray Ring (X1 beam line) at the National Synchrotron Light Source at Brookhaven National Laboratory in June 1988. Prior to its installation extensive magnetic measurements were performed at the NSLS Magnetic Measurements Lab in order to determine the operating values for the end corrector currents, the field quality, and the integrated multipoles associated with the magnet as a function of gap. This report is intended to summarize the results of these measurements. The iron poles are 18mm {times} 32mm {times} 86mm, and the Samarium Cobalt permanent magnet blocks are 22mm {times} 21mm {times} 110mm. In each of the magnet halves there are 76 slots, 70 of which were filled with two magnets per slot, and 6 of which were left empty (3 each on the upstream and downstream ends of the magnet). These slots were left empty in order to approximate an infinitely long magnet in the algorithm for the magnet block sorting. The magnet period is 80mm, and the gap range is 31--100mm, with field values of 3500 and 200 Gauss respectively. For this gap range the undulator parameter K, where K = 0.934 B(Tesla) {lambda}(cm), ranges from 2.6 to 0.15. 14 figs., 5 tabs.
