Measurement accuracy of ±2mm and repeatability of ±0.15mm
Keyence gap readings track with post temperatures
Cold In-Situ Field Measurement
In-vacuum mapper with Hall probe. The postion accuracy is maintained by laser tracker and piezo controller.
also in consideration
Tracking studies are needed to determine the effect
of dynamic aperture reduction due to these roll-offs.
