Title
The Luge, a high-speed, precision magnetic measurement system
Description
Allowable magnetic field errors for Advanced Light Source (ALS) undulators are extremely small and are driven by electron beam and radiation requirements. To measure the magnetic field of an insertion device, the ALS designed and built a high-speed, precision magnetic measurement system. It uses Hall-probe mapping equipment to obtain local and integrated field information. Nicknamed the Luge, it consists of a custom-built stage that translates through the gap of the undulator. The system is capable of taking 2500 measurements during one pass through the insertion device in under one minute. A laser interferometer system gives precise tracking of the probe to an accuracy of ±1 µm.
