A beamline has been established at the National Synchrotron Light Source to perform angle‐resolved photoemission experiments on magnetic surfaces with spin sensitivity. The system has two novel features: it uses a miniature electron‐spin polariza

A total of five beam lines are currently being constructed and commissioned at the NSLS. They involve a 2.75° toroidal grating monochromator, a plane grating grazing monochromator, a large aperture modified Wadsworth monochromator, a Seya-Namioka in

The proposed installation of an experimental beam line to exploit the photon flux from the FEL undulator on the Brookhaven VUV ring is described. It is shown that under the normal operating conditions of the VUV ring, the undulator should produce an

The design and operating characteristics of the VUV undulator installed on the NSLS VUV ring are presented. Specifically, the spectral output through three circular on-axis pinholes of different diameters has been measured. Near the minimum magnetic

We describe the infrared beamline which is being constructed at the NSLS. In order to maintain the high brightness at long wavelengths (up to 1 mm) where diffraction becomes a problem, a high aperture extraction port is used. Problems of cooling of t
