The FS-US undulator lab provides a variety of magnetic and mechanical measurement tools in an air-conditioned environment. Before installation in the accelerator tunnel each insertion device needs to be carefully characterized and tuned to meet the stringent specifications of accelerator division and experiment. The primary tools are a two granite benches equipped with a Hall-probe and a pick-up coil mounted on a goniometer to spatially resolve local magnetic field distributions, main features are:

Permanent magnet blocks are individually characterized before being sorted and mounted into an insertion device. For this characterization we use:
Other tools available in the lab are:

Other tools for local and integral magnetic measurements are under present development, e.g. a pulsed wire setup or a rotating coil.
