Field Measurement System in Vacuum for a Cryogenic Permanent-Magnet Undulator at NSRRC
A recent trend toward building an undulator for a mid-energy storage ring is a small period length and a large magnetic field, which typically requires a vacuum and cryogenic environment.

Summary: | A recent trend toward building an undulator for a mid-energy storage ring is a small period length and a large magnetic field, which typically requires a vacuum and cryogenic environment. To measure the magnetic field of such undulators, we designed and fabricated a Hall-probe measurement system in vacuum. All components of this system are installed in a vacuum chamber and are compatible with a high-vacuum and a low-temperature environment; the deployment of all parts is designed to fit a cryogenic permanent-magnet undulator that is now under construction at the National Synchrotron Radiation Research Center. The details of the design, completed fabrication, and test results are presented in this paper. |
