About This Project

The Stanford Linear Accelerator Center (SLAC) needed a calibration shield for a moving Hall Effect Probe as part of their Undulator Project with DESY — the German Synchrotron Facility. Typical Zero Gauss Chambers consist of an open-ended tube, which was unacceptable in SLAC’s Undulator configuration.

The design originated as a single slot Undulator shield and was so successful, that it was graduated to the dual slot system shown above, which enabled full pass-through of the Hall Probe.

The probe needed to pass through the shield lengthwise. By equating the flange width to “end effects” on a cylinder, and with an understanding of the customer’s application, we applied tubulation theory to a slot configuration to reduce fringing and end effects.

Note the Magnetic modeling image – confirmed what extensive testing proved.
